Please refer to attached emails and specifications.
Per specification section 321216 Asphalt Paving, a herbicide is to be applied over the road base before any asphalt
paving is installed to protect against future weeds. Per email correspondence between FCI, Chamberlin Architects and
Roaring Fork Engineering it was confirmed that the application of the herbicide will not be required for this project.

3. Use hot-applied joint sealant to seal cracks and joints more than 1/4 inch wide. Fill flush
with surface of existing pavement and remove excess.
3.5 SURFACE PREPARATION
A. General: Immediately before placing asphalt materials, remove loose and deleterious material
from substrate surfaces. Ensure that prepared subgrade is ready to receive paving.
B. Herbicide Treatment: Apply herbicide according to manufacturer's recommended rates and
written application instructions. Apply to dry, prepared subgrade or surface of compacted-
aggregate base before applying paving materials.
1. Mix herbicide with prime coat if formulated by manufacturer for that purpose.
C. Prime Coat: Apply uniformly over surface of compacted unbound-aggregate base course at a
rate of 0.15 to 0.50 gal./sq. yd. Apply enough material to penetrate and seal but not flood
surface. Allow prime coat to cure.
1. If prime coat is not entirely absorbed within 24 hours after application, spread sand over
surface to blot excess asphalt. Use enough sand to prevent pickup under traffic. Remove
loose sand by sweeping before pavement is placed and after volatiles have evaporated.
2. Protect primed substrate from damage until ready to receive paving.
D. Tack Coat: Apply uniformly to surfaces of existing pavement at a rate of 0.05 to 0.15 gal./sq.
yd.
1. Allow tack coat to cure undisturbed before applying hot-mix asphalt paving.
2. Avoid smearing or staining adjoining surfaces, appurtenances, and surroundings.
Remove spillages and clean affected surfaces.
3.6 PAVING GEOTEXTILE INSTALLATION
A. Apply tack coat uniformly to existing pavement surfaces at a rate of 0.20 to 0.30 gal./sq. yd.
B. Place paving geotextile promptly according to manufacturer's written instructions. Broom or
roll geotextile smooth and free of wrinkles and folds. Overlap longitudinal joints 4 inches and
transverse joints 6 inches.
1. Protect paving geotextile from traffic and other damage and place hot-mix asphalt paving
overlay the same day.
3.7 HOT-MIX ASPHALT PLACING
A. Machine place hot-mix asphalt on prepared surface, spread uniformly, and strike off. Place
asphalt mix by hand to areas inaccessible to equipment in a manner that prevents segregation of
mix. Place each course to required grade, cross section, and thickness when compacted.
1. Place hot-mix asphalt base course in number of lifts and thicknesses indicated.
2. Place hot-mix asphalt surface course in single lift.

Daniel,
Since there isn’t much potential for recurrent vegetation growth here, I agree with the paver that it would be acceptable
to not use the herbicide in this situation.
Thanks,
Sean

Richard,
Project specs call for a herbicide to be applied over road base prior to asphalt paving. We have the costs for that
covered, but in talking with our paver, they don’t think it is needed and not worth the expense Any thoughts on that? It
would be about a $5,000 savings to the County.
