Description Of Change
Order
Contract Information
Change Order Form Revision 1 /19/2024
Work on 9/9/24 uncovered significant structural issues that
were previously unknown and hidden beneath layers of concrete
and asphalt which require emergency repairs.
Key findings:
• The previous concrete overlay or top layer on the bridge deck
has failed in several areas.
• Severe degradation of reinforcing rebar has been found in
multiple locations —some areas show only discoloration where
rebar has corroded away.
• Steel reinforcement is no longer viable in critical sections,
affecting the structural integrity of the bridge.
• This bridge functions as a single unit, so failure in one part
compromises the entire structure.
• The structure is deteriorating from the outside in, with
exposure to elements causing ongoing damage.
Acting now will stabilize the bridge at its current state by
repairing damaged reinforcement and sealing the bridge
elements.
Estimated costs of the emergency repairs is $184,220 and
$281157495 (15%) in contingency to complete:
1. Repair concrete bridge deck at North sidewalk and South
sidewalk.
2. Install epoxy coating of sidewalks at North and South side of
bridge. $25,000.00 Lump sum. Includes labor, equipment,
sandblasting and epoxy.
3. Provide 1 way traffic control to accommodate the work.
This estimate and includes:
• Contractor labor and equipment
• Materials
• Traffic control
• Testing
• Project extension up to 4 weeks
This estimate reflects a comprehensive view of the current
situation. Once additional layers are removed, we will have a
clearer picture of the full scope therefore this change order will
be executed on a Time and Materials (T&M) basis.

401.01
401.01 These specifications include general requirements that are applicable to all types of hot mix asphalts irrespective of
gradation of aggregate, kind and quantity of asphalt cement, or pavement use. Deviations from these general requirements will be
indicated in the specific requirements for each type.
This work consisfs of one or more courses of asphalt mixture constructed on a prepared foundation per these specifications and
the specific requirements of the type under contract, and in conformity with the lines, grades, thicknesses, and typical cross
sections shown on the plans or established.
401.02 Composition of Mixtures. The asphalt plant mix shall be composed of a mixture of agg�•egate, filler or additives if
required and approved, asphalt cement, and reclaimed matey ial if permitted and used.
Design. The Contractor shall submit the following to the Engineer:
1. A proposed hot mix asphalt mix design prepared per Colorado Procedure 52, including a proposed job -mix gradation for
each mixture required by the Contract, which shall be wholly within the Master Range Table in subsection 703.04 before
the tolerances shown in Section 401 are applied. The weight of lime shall be included in the total weight of the material
passing the 75 µm (No. 200) sieve.
2. The name of the refineryery supplying the asphalt cement and the source of the anti -stripping additive.
3. A sufficient quantity of each aggregate for the Department to perform the tests specified in Section 3.2.1 of CP 52,
The Contractor's proposed job -mix formula for each hot mix asphalt grading will be tested by the Department utilizing
materials actually produced and stockpiled for use on the project.
The job -mix formula for• each mixture shall establish a single percentage of aggregate passing each required sieve size, a
single percentage of asphalt cement to be added to the aggregate, and a single temperature for the mixture at the discharge
point of the plant.
When Laboratory tests indicate that a proposed job -mix formula complies with the specifications as revised for the project, a
Form 43 shall be executed between the Engineer and the Contractor to establish the job -mix formula.
After the Form 43 is executed, and all materials are available on the project, the Contractor shall notify the Engineer a
minimum of one working day in advance of beginning production of the hot mix asphalt. Any changes in the Form 43 will
require the same notification unless otherwise approved by the Engineer.
(b) Nlixtaires Furnished to the Project. After the job -mix formula is established, all mixtures furnished for the project shall
conform thereto within the ranges of tolerances listed in Table 401-1.

The job -mix formula for each mixture shall be in effect unless modified in writing on Form 43.
Should a change in sources of materials be made, a new job -mix formula shall be established before the new material is
used. This new job -mix formula shall be in effect until modified by the Engineer. Requests made in writing by the
Contractor for changes in the job -mix formula will be considered. The job -mix formula may be changed by the Engineer
if the change will produce a mixture of equal or better quality and will:
1, Permit better utilization of available material, or
2. Result in a saving in cost to the Department through an adjustment in unit price.
Tests for cleanliness, abrasion loss, and percent of fi•actured faces will be made on representative samples of aggregate
taken during production or from the stockpiles.
Hot mix asphalt (HIvIA) will be tested for moisture susceptibility by the Department per Table 401-2. If a sample fails to
meet the criteria shown in Table 401-2, the Contractor shall take corrective action before being permitted to continue
production. If proper corrective action cannot be readily determined, the Engineer will suspend the use of such material
until Laboratory tests indicate that the corrective measures taken by the Contractor will provide material that is in
compliance.
If one or more samples fail to meet the requirements of Table 401-2, material from the area represented by the failing
sample will be evaluated as follows:
If the area represented by the failing sample contains 2;000 tons of the new pavement or less, then the result for the
failing sample shall be considered a lot of one and will be evaluated according to the formulas and procedures in
subsection 105,03,
If the area represented by the failing sample contains more than 2,000 tons of the new pavement, then the material from
the area represented by the failing sample will be sampled and tested according to the following method:
Pavement samples for• possible moisture susceptibility testing will betaken at a minimum frequency of once every 2,000
no throughout the project. The Engineer will observe the sampling, take possession of the samples, and retain these
samples for possible testing. Sample size shall be a minimum of 20 pounds. If a 10,000-ton sample fails, then the four
2,0004on samples from the area represented by that failing 10,000-ton sample will be tested for moisture susceptibility.
The 10,000-ton result and the four 2,000-ton results will be considered a lot of five and will be evaluated according to
the formulas and procedures in subsection 105,03. If less than four retained samples are on hand because the I0,000-ton
sample represents less than 8,000 tons of hot mix asphalt, the price adjustment will be based on the test results from the
retained samples on hand plus the test result from the 10,000-ton sample.
For the above evaluation, the "F" factor used in calculating P factors shall be 2.5. The P value shall be applied to price of
the HMA item. If asphalt cement is not paid for separately, the price reduction shall be multiplied by 0,60. Coffman P
values will not be combined with Pay Factors for other elements determined per Process Control/Owner Acceptance
(PC/OA) specifications.

When hydrated lime is used it shall be added to the aggregate per one of the following methods:
(a) Lime SluriyAdded toAggiegate, The hydrated lime shall be added to the aggregate in the form of a slurry and then
thoroughly mixed in an approved pugmill, The slurry shall contain a minimum of 70 percent water by weight.
(b) Dly Lime Added to Met Aggregate, The dry hydrated lime shall be added to the blended aggregate wetted a minimum of
2 percent above the surface saturated dry condition (SSD) as shown on the Form 43, and then thoroughly mixed in an
approved pugmill. The Engineer will not require the Contractor to increase the moisture above 5 percent total, although
the Contractor may elect to do so if the added water is necessary to meet the minimum Lottman specification (See Table
401-2).
The Contractor may request that the 2 percent above SSD r•equir•ement be waived, provided the t•equirements of CPL 5150
have been met. If the HMA fails to meet the minimum TSR requirements defined in Table 401-2 at any point during
production, the Contractor shall immediately be required to add the minimum amount of moisture as defined above,
The lime -aggregate mixture may be fed directly into the hot plant after mixing or it may be stockpiled for not more than 90
days before introduction into the plant for mixing with the asphalt cement, The hydrated lime may be added to different sized
aggregates and stockpiled, by adding 75 percent of the lime to the aggregate passing the 4,75 mm (No. 4) sieve and 25
percent to the aggregate retained on the 4.75 mm (No, 4) sieve.
In order to ensure the required lime and water quantities are introduced, lime and water feed for lime operation shall have
control systems that change introduction rates in conjunction with changes in plant mix production. The control systems
shall be documented in the Contractor's PC Plan,
When a test for aggregate percent moisture falls below the required minimum, the Contractor will receive a warning. When
two consecutive tests for aggregate percent moisture fall below the required minimum, a follow up test will immediately be
performed. A failure on the follow up test will result in suspension of work, Production will remain suspended until the
source of the problem is identified and corrected, Each time production is suspended, corrective actions shall be proposed in
writing by the Contractor and approved in writing by the Engineer before production may resume,
401.15 Mixing, The dried aggregates and asphalt shall be combined in the mixer in the quantities required to meet the job-
rnix formula.
The materials shall be mixed until the aggregate is completely and uniformly coated, and the asphalt is uniformly distributed
tht•oughout the aggregate.

Hot mix asphalt mixture shall be produced at the lowest temperature within the specified temperature range that produces a
workable mix and provides for uniform coating of aggregates (95 percent minimum per AASHTO T 195), and that allows the
required compaction to be achieved.
Storing or holding of asphalt mixture will be permitted provided the characteristics of the mixture are not altered. If storing or
holding of the mixture causes segregation, excessive heat loss, or adversely affects the quality of the finished product, corrective
action shall be taken. Unsuitable mixture shall be disposed of at the Contractor's expense.
When placing hot asphalt mixture over bridge decks covered by waterproofing membrane, the minimum temperature of the
mixture when tolling operations begin shall be 250'F. The job -mix formula temperature may be increased up to 30 °F to obtain
this temperature.
401.16 Spreading and Finishing. Asphalt pavers shall be used to distribute the mixture to the established grade and required
thickness over the entire width or partial width as practicable.
The longitudinal joint in both a new pavement and an overlay pavement layer shall offset the joint in the layer immediately below
by 6 inches. In every pavement layer, the longitudinal joints shall not be constructed in the wheel paths. The Contractor shall
submit a longitudinal joint and pavement marking plan three days before the Pre -paving Conference, The plan shall show the
location and configuration of the proposed longitudinal joints and pavement markings and shall detail the methods to be used to
field establish a control line. The Contractor shall use a continuous string line to delineate every longitudinal joint during paving
operations. All exposed string line shall be picked up and disposed of at the end of each day's paving. Paving shall not
commence until the plan has been approved in writing by the Engineer. The joints in the top layer of pavement shall be located as
follows unless otherwise approved in writing by the Engineer:
1. For 2-lane roadways, offset 6 to 12 inches from the center of pavement and from the outside edge of travel Lanes.
2. For roadways of more than 2 lanes, offset 6 to 12 inches from lane lines and outside edge of travel lanes.
Longitudinal joints shall not cross the centerline, lane line, or edge line unless approved by the Engineer.
Where paving operations are on the present traveled roadway, the Contractor shall arrange paving operations so there will be no
exposed longitudinal joints between adjacent travel lanes at the end of a days run. With the approval of the Engineer, the
Contractor may leave an exposed longitudinal joint conforming to the following:
1, When the thickness of the pavement course being placed is 1.5 inches or less a vertical exposed longitudinal joint maybe
constructed.
2. When the thickness of the pavement course being placed is greater than 1.5 inches the joint shall be constructed according to
one of the following:
A. The entire joint shall be tapered 3;1 or flatter. A Taper steeper than 3:1 shall be considered vertical.
B. The top portion of the longitudinal joint may be vertical. The vertical portion shall be a maximum of 1.5 vertical inches.
The remainder° of the joint, below the vertical portion, shall be tapered 3;1 or flatter.
On areas where the use of mechanical spreading and finishing equipment is impracticable, the mixture shall be dumped,
spread, raked, sct•eeded, and luted by hand tools to the required compacted thickness and grades.
Production of the mixture shall be maintained so pavers can be used in echelon to place the wearing course in adjacent lanes.
The asphalt mixture shall be transported and placed on the roadway without segregation. All segregated areas behind the '
paver shall be removed immediately upon discovery, The segregated material shall be replaced with specification material
before the initial rolling has taken place. If more than 50 square feet of segregated pavement is ordered removed and replaced
in any continuous 500 linear feet of paver width laydown, operations shall be discontinued until the source of the segregation
has been found and corrected.
If at any time, the Engineer observes segregated areas of pavement, they will notify the Contractor immediately,
After rolling, segregated areas will be delineated by the Engineer and evaluated as follows:
1. The Engineer will delineate the segregated areas to be evaluated and inform the Conh•actor of the location and extent of these
areas within two calendar days, excluding weekends and holidays, of placement.

401.17
2. In each segregated area or group of areas to be evaluated, the Contractor shall take five 10-inch cores at random
locations designated by the Engineer. Per CP 75, the Contractor shall also take five 10-inch cores at random locations
designated by the Engineer in non -segregated pavement adjacent to the segregated area. These cores shall be within 30
feet of the boundary of the segregated area and in the newly placed pavement. The coring shall be in the presence of the
Engineer and the Engineer will take immediate possession of the cores. The Contractor may take additional cores at the
Contractor's expense.
3. Gradation of the aggregate of the cores will be determined by CDOT per CP 46.
4. The core aggregate gradations from the segregated area will be compared to the core aggregate gradations of the
corresponding non -segregated area.
5. Two key sieves of the core gradations fi•om the segregated area will be compared to the core gradations fi•om the
corresponding non -segregated area to determine the difference. If differences for both key sieves exceed the allowable
difference specified in the table below, the area is segregated.

6. Segregated areas in the top lift shall be removed and replaced, full lane width, at the Contractor's expense. The Engineer
may approve am o equivalent to removal and replacement that results in a non -segregated top lift. Segregated areas, in
lifts below the top lift that are smaller than 50 square feet per 100 linear feet of lane width shall be corrected by the
Contractor at the Contractor's expense in a manner acceptable to the Engineer. Segregated areas larger than 50 square feet
per 1001inear feet of lane width in any lift shall be removed and replaced, full lane width, by the Contractor at the
Contractor's expense.
If the area is determined to be segregated, the coring shall be at the expense of the Contractor. If the area is determined
to be non -segregated, the Engineer will reimburse the Contractor $2,000 for obtaining the10 cores.
The Engineer will perform a systematic segregation check per CP 58 as early in the project as is feasible to determine if
temperature segregation problems exist. Temperahrre segregation will be of concern on the project if, across the width of the
mat, temperatures vary by 25 IF or more. Densities will not need to be taken in the systematic segregation check. The
Engineer will discuss the temperature findings of the systematic segregation check with the Contractor.
The Engineer may evaluate the I-iMA for low density due to temperature segregation whenever industry best practices, as
detaIled on Form 1346, ar•e not being followed or the Engineer suspects temperature segregation is occurring. The Engineer
wHI first meet with the Contractor to discuss the paving practices that are triggering the temperature investigation. Areas
across the mat, excluding the outside 1 foot of both edges of the mat, that are more than 25 °F cooler than other material
across the width may be marked for density testing. Material for temperature comparison will be evaluated in 3-foot intervals
behind the paver across the width of the mat, The material shall be marked and tested per CP 58. If four or more areas
within a lot of 500 tons have densities of less than 93 percent of the material's maximum specific gravity for• SMA mixes or
less than 92 percent of the material's maximum specific gravity for all other HMA mixes, a 5 percent price disincentive will
be applied to the 500-ton lot. The 5004on count begins when the Engineer starts looking foil cold areas, not when the first
cold area is detected. This price disincentive will be in addition to those described in Sections 105 and 106. Only one area
per delivered truck will be counted toward the number of low -density areas. Temperature segregation checks will be
performed only in areas where continuous paving is possible.
401.17 Compaction. The hot mix asphalt shall be compacted by rolling. Both steel wheel and pneumatic tire rollers will be
required. The number, weight, and type of rollers furnished shall be sufficient to obtain the required density while the mixture
is in a workable condition. Compaction shall begin immediately after the mixture is placed and be continuous until the
required density is obtained. When the mixture contains unmodified asphalt cement (PG 58-28 or PG 64-22) or modified (PG
58-34), and the surface temperature falls below 185 °F, further compaction effort shall not be applied unless approved,
provided the Contractor can demonstrate that there is no damage to the finished mat. If the mixture contains modified asphalt
cement (PG 76-28, PG 70-28 or PG 64-28) and the surface temperature falls below 230 °F, further compaction effort shall not
be applied unless approved, provided the Contractor can demonstrate that there is no damage to the finished mat.

401.17
Warm Mix Asphalt compaction requirements shall conform to CP 59.
All roller marks shall be removed with the finish rolling. Use of vibratory rollers with the vibrator on will not be permitted during
surface course final rolling and will not be permitted on any rolling on bridge decks covered with waterproofing membrane.
S1VIA shall be compacted to a density of 93 to 97 percent of the daily theoretical maximum specific gravity, determined accor°ding
to CP 51. All other FIMA shall be compacted to a density of 92 to 96 percent of the daily theoretical maximum specific gravity,
determined according to CP 51. If more than one theoretical maximum specific gravity test is taken in a day, the average of the
theoretical maximum specific gravity results will be used to determine the percent compaction. Field density determinations will
be made per CP 44 or 81.
The longitudinal joints shall be compacted to a target density of 92 percent of the theoretical maximum specific gravity. The
tolerance shall be plus or minus 4 percent. The theoretical maximum specific gravity used to determine the joint density will be
the average of the daily theoretical maximum specific gravities for the material that was placed on either side of the joint. Density
(percent relative compaction) will be determined per CP 44.
The Contractor shall obtain one 6-inch diameter core at a random location within each longitudinal joint sampling section for
determination of the joint density. The Contractor shall mark and drill the cores at the location directed by the Engineer and in the
presence of the Engineer. The Engineer will take possession of the cores for testing. The Contractor may take additional cores at
his own expense. Coring locations shall be centered on the visible line where the joint between the two adjacent lifts abuts the
surface. The center of all joint cores shall be within 1 inch of this visible joint line. Core holes shall be repaired by the Contractor
using materials and methods approved by the Engineer. PC and OA joint coring shall be completed within five calendar days of
joint construction.
Longitudinal joint coring applies to all pavement layers. When constructing joints in an echelon paving process, the joints shall be
clearly marked to ensure consistent coring location. In small areas, such as intersections, where the Engineer prescribes paving
and phasing methods, the Engineer may temporarily waive the requirement for joint density testing
Incentive or disincentive payment determined for joint density per subsection 105.05 will apply to the IRVIA on each side of the
joint. If a layer of pavement has joints constructed on both sides, incentive or disincentive payment for each of those joints will
apply to one half of the pavement between the joints.
Along forms, curbs, headers, walls, and all other places not accessible to the rollers, the mixture shall be thoroughly cornpacte&
with mechanical tampers.
Any mixture that becomes loose and broken, mixed with dirt, or is in any way defective, shall be immediately removed and
replaced with fresh hot mixture, and compacted to conform to the surrounding area.
The Contractor shall construct a compaction pavement test section (CTS) for each job mix where 2,000 or more tons are required
for the project. The CTS will be used to evaluate the number of rollers and the most effective combination of rollers and rolling
patterns for achieving the specified densities. Factors to be considered include, but are not limited to, the following:
(1) Number, size, and type of rollers,
(2) Amplitude, frequency, size and speed of vibratory rollers.
(3) Size, speed, and tire pressure of rubber tine rollers.
(4) Temperature of mixture being compacted.
(5) Roller patterns.
The CTS shall be constructed according to the following procedures:
The CTS shall be constructed to provide the nominal layer thickness specified. The first 500 tons of hot mix asphalt on the project
location shall constitute the CTS. The production and placement rates of the CTS shall closely approximate the anticipated
production and placement rates for the remainder of the Contract.
Compaction of the CTS shall commence immediately after the hot mix asphalt has been spread and shall be continuous and
uniform over the entire CTS. For the CTS, compaction shall continue until no discernible increase in density is obtained by
additional compaotive efforts. All compaction shall be completed before the surface temperature of the mixture drops below 185
°F
Approved types of rollers shall be used to achieve the specified density. The Contractor shall determine what methods and
procedures are to be used for the compaction operation. The compaction methods and procedures shall be used uniformly over _
the entire last 200 tons. The Contractor shall record the following information and a copy of this data shall be furnished to the
Engineer.

(1) Type, size, amplitude, frequency, and speed of roller.
(2) Tire pressure for rubber tire rollers, and whether the pass for vibratory rollers is vibratory or static.
(3) Surface temperature of mixture behind the laydown machine and subsequent temperatures and densities after each roller
pass.
(4) Sequence and distance from laydown machine for each roller, and number of passes of each roller to obtain specified
density.
Two sets of random cotes shall be taken within the last 200 tons of the CTS. Each set shall consist of seven random
cores. The Engineer will determine the coring locations using a stratified random sampling process. The locations of
these cores will be such that one set can serve as a duplicate of the other. One set of these cores shall be immediately
submitted to the Engineer. This set will be used for determining acceptance of the CTS and determining density
correction factors for nuclear density equipment. Densities of the random samples will be determined by cores according
to CP 44. Density correction factors for nuclear density equipment will be determined according to CP 81. Coring shall
be performed under CDOT observation. Coring will not be measured and paid for separately but shall be included in the
work. For SMA, a CTS is not used. The Contractor shall follow the requirements for the demonstration control strip per
the Revision of Section 403, Stone Matrix Asphalt Pavement,
The CTS meets requirements if the Quality Level of the random samples is greater than or equal to 75. The Quality
Level will be determined according to CP 71. Once constructed and accepted, the CTS shall remain in place and become
part of the hot mix asphalt on the project.
When the Quality level is less than 75 the Contractor shall construct an additional test section, utilizing different rollers,
or roller positions, or roller patterns as required. A written proposal detailing the changes in methods and procedures that
will be used to obtain density is to be submitted to the Engineer for review before constructing the additional test section.
If the Quality Level of a CTS is less than 75 and greater than orqual to 44, the Engineer may accept the material at a
reduced price per Section 105.
If the Quality Level of a CTS is less than 44, the Engineer may:
(1) Require complete removal and replacement with specification material at the Contractor's expense.
(2) Where the fmished product is found to be capable of performing the intended purpose and the value of the finished
product is not affected, as determined by the Engineer, permit the Contractorto leave the material in place with a pay
factor, but not more than 75 percent of the bid price.
Each CTS shall be 500 tons. If in -place densities of the CTS, as determined by nuclear density equipment before determining
density of the cores, meet the CTS density requirements, the Contractor may begin production paving and continue to place
hot mix asphalt pavement under the following conditions:
(1) The period during which the Contractor continues to pave without test results from cores shall not exceed one workday.
(2) Construction proceeds at the Contractor's risk. If correlation with the cores reveals that the densities do not meet the
CTS requirements, the hot mix asphalt pavement placed subsequently will be subject to price reduction or removal and
replacement.
After production paving work has begun, a new Roller Pattern shall be demonstrated when a change in the compaction
process is implemented.
All additional costs associated with construction of the CTS shall be at the Contractor's expense. The hot mix asphalt placed
in the CTS will be paid for per subsection 401.22, at the contract price for the hot mix asphalt.
401.18 Joints. Placing of the hot mix asphalt shall be continuous, and rollers shall not pass over the unprotected end of a
freshly laid mixture. Transverse joints shall be formed by cutting back on the previous run to expose the full depth of the
course. A coat of asphalt cement shall be applied to contact surfaces of all joints just before additional mixture is placed
against the previously compacted material, Location and configuration of longitudinal joints shall be per subsection 401,16.
401.19 Pavement Samples. The Engineer may take samples of the compacted pavement at random locations on the project
for testing. Where samples have been taken, new material shall be placed and compacted by the Contractor to conform with
the surrounding area.
401.20 Surface Smoothness. The roadway surface smoothness shall be tested per subsection 105.07.
