The City of Aspen has endorsed this approach and the Preannexation Agreement states: “City also agrees that, because of its rural character and location outside of the City’s street grid system, the Residential Design Standards of Chapter 26.410 of the Aspen Land Use Code, and the requirements for street paving, sidewalks, curbs and gutters, shall not be applied to the Free Market Component, including the Fathering Parcel. Landowner, as part of the land use approval process shall propose and agree to adopt design standards that are appropriate for the Free Market Component. The homeowners’ association for the Free Market Component shall be responsible through covenants running with the land to enforce the adopted design standards.” Despite this, the existing Stage Road needs some substantial improvement in order to carry the additional traffic loads. This section contains the engineering for the improvement of Stage Road, its northerly extension, the construction of Stage Road South, and the pond iomprovements. AirQuality The gravelled surface of Stage Road is presently the ranch’s major contribution to air pollution, although the average particulate size is relatively large. A fully paved road allows particles to be ground much finer by traffic so that although the visibility of pollution may be much less, the health hazrds from PM-10 and even PM-2 particulates is, in fact, much greater. After considerable research, we propose the use of a product called “Road-Oyl” to seal the surface of the subdivision roads. It is based on pine resin and has no known negative environmental effects. This product was originally developed to control dust generation from heavy traffic on unpaved mine roads that had to meet strict environmental standards. Although relatively expensive it offers the ability to preserve the character of gravelled roads and substantially reduce the current air pollution. 20.3Road Engineering WHERE TO USE ROAD OYL Developed to solve dust problems found in the severe conditions on mine haul roads, ROAD OYL®is ideal for all areas where problem dust is an issue. ROAD OYL®has been specifically designed and proven to be a long-term solution for efficient control of road dust as well as for use on mine tailings, stockpiles, and for erosion control. Traffic on a ROAD OYL®surface will compact the road into a smooth dust free pavement-like surface. EASY TO APPLY •For rough roads, grade first •Dilute ROAD OYL®with water •Apply in multiple light passes rather than one heavy pass •Re-apply as needed ENVIRONMENTALLY FRIENDLY Made from all natural products harvested on a sustainable basis, ROAD OYL®is non-hazardous and safe for the environment. ECONOMICAL ROAD OYL®is shipped efficiently as a high concentrate and diluted with water before application. With it's long lasting nature, you spend less time reapplying, saving you both time and money. LONG LASTING The condition of the road, the degree of ROAD OYL®penetration, and the amount of traffic combine to determine the life of a ROAD OYL®application. ROAD OYL® may help stabilize the road in winter by protecting the road from water intrusion. NO SPECIAL EQUIPMENT NEEDED ROAD OYL®can be easily applied using a standard spray truck. An experienced ROAD OYL® Distributor will work with you to insure a success- ful ROAD OYL® dust control program. ROAD OYL®penetrates road aggregate and binds it into a surface proven stronger than asphalt.

How long will it last? It depends on a number of factors such as traffic, track-on, and spillage as well as the condition of the road. Applications are cumulative, so reapplications should become more dilute and less frequent until the maintenance level is reached. 2.Who else is using it? ROAD OYL® has been used all over the world for over 15 years, from the U.S. Military in Turkey and Somalia, landfills in Los Angeles, steel mills in St. Louis, coal mines in Kentucky, Virginia, and West Virginia to gold mines in Indonesia. 3.What dilution ratio should I use? ROAD OYL® can be diluted from 4:1 to 15:1 with water. The lower the dilution the more control you will get with each application and the less often you should have to spray. With track on or spillage, use higher dilutions and spray more often. 4. Is it EPA approved? ROAD OYL® is made from all natural ingredients harvested on a sustainable basis. It has never had a problem being approved for use in any application or as part of an environmental permit issued to an operating entity such as a landfill, steel mill, or mine. 5.Will it harm the water truck? No. When finished spraying, flush the system with water until it runs clear. 6.Will it get on the vehicles? When freshly applied, it might splash on nearby vehicles. 7. How do I clean it up? Fresh splashed product can be flushed off with water. Dried product can be cleaned with hot water and detergent. 8.Will it track? Road Oyl will not track when applied as directed. Excessive application or oversaturation will track when freshly applied. 9. Does it cause rust? No. It is non-corrosive as well as non-hazardous, non-flammable, and non-toxic. 10.Will it harm my roads? No. Unlike salts or other water soluble products, it will actually help stabilize the road rather than draw excessive moisture to the road base that can be harmful. 11. Do I need to grade the roads first? It is not necessary to grade the road. However, we recommend, if the road is rough, grading the road first. 12. How much does it cost? Road Oyl is an economical solution to dust control. Remember, this is a concentrate that is diluted from 4:1 to 15:1 with water before use. Your actual cost will be determined by the dilution ratio and frequency of application.

June 2003 20.5Road Engineering Paving without Asphalt or Concrete from Volume 8, Number 11 -- November 1999 This article was originally published in Environmental Building News, the leading newsletter on environmentally responsible design and construction; subscribe and read more! Asphalt and concrete account for the vast majority of paving today. These materials are very different: asphalt is a mix of aggregate and leftover heavy hydrocarbons after more valuable, lighter fractions of crude oil have been extracted; concrete is a hard- ened, rock-like material usually made by mixing Portland cement with sand, coarser aggregate, and water. In the green design community, there is some interest in avoid- ing these conventional pavement products in favor of more natural, less energy-inten- sive materials using locally available aggregates and bio-based binders. ROAD OYL® Resin Pavement™ from Soil Stabilization Products of Merced, California is such an alternative. ROAD OYL, introduced in 1991, is an emulsion formulated from pine rosin and pitch in water. (An emulsion, for those whose high school chemistry is rusty, is a mixture in which globules of one liquid are suspended - but not dissolved - in a second liquid.) The pitch and rosin, which comprise roughly 50% of ROAD OYL by weight, are co- produced with other timber products from southern pine in the southeastern United States. Pine pitch is a black, viscous “tar” derived from the distillation of wood; before the development of coal-tar pitch, pine pitch was used to impregnate building papers and felt, and to saturate hemp fiber for oakum. Pine rosin is the residue from distilla- tion of turpentine oil from raw turpentine. The ROAD OYL liquid is brownish in color with a mild odor. When rubbed between the fingers, it becomes extremely sticky as the water evaporates (and is hard to wash off!). It is shipped as a liquid by the 6,000- gallon (22,700 l) truckload or 55-gallon (210 l) drum. For paving, ROAD OYL is mixed with crushed stone -- usually decomposed granite -- that includes a range of particle sizes, from 1/2” (13 mm) or 3/4” (19 mm) down to fines or filler that pass through a #200 sieve (75 µm). In the company’s recommended 3/4” aggregate mix, one-quarter to one-half of the aggregate should pass through a #8 (2.4 mm) sieve. Ideally, the aggregate should not include organic matter or clay particles, though clayey mixes are sometimes used satisfactorily. The aggregate is typically wetted (2% to 4% water), then the ROAD OYL emulsion is added at 6% to 9% by weight, depending on the application and the aggregate. The aggregate and emulsion mixture is then laid down using fairly conventional paving equipment and practices. In remote areas, such as along park trails, small-scale equipment and hand labor are often used. 20.6 Bar Slash X Ranch LLC - Annexation and Stage Road PUD/Subdivision: Final Submission After compacting or rolling and several days of cure time, Resin Pavement forms a hard, durable surface that contains neither petroleum derivatives nor cement. Un- like asphalt, which hardens by cooling, or concrete, which hardens through a chemi- cal hydration process, Resin Pavement hardens through evaporation of the water carrier. And harden it does. The compressive strength of Resin Pavement typically exceeds that of conventional asphalt by more than threefold. It is also highly water- resistant and can withstand heavy wash and even flooding. In some applications, where greater compressive strength is required or the underlying roadbed is weak, the company’s EMC Squared® soil stabilization product is applied to the soil prior to laying down the Resin Pavement -- soil stabilization products will be addressed in a future article. Because Resin Pavement is not softened by contact with hydrocarbon solvents (as asphalt is), this system is also commonly used around fuel storage facili- ties. The ROAD OYL emulsion darkens the aggregate slightly but maintains the same basic look, which makes this system desirable in natural settings. Note that this is not a porous paving product; with the high content of fines (required for proper hardening), the cured pavement is highly impermeable. Test data provided to EBN by the company showed ROAD OYL to be quite clean compared with asphalt. As part of the U.S. Environmental Protection Agency National Estuary Program, testing was conducted by Analytical Chemical Testing Laboratory of Mobile, Alabama in the Spring of 1999 to verify the suitability of ROAD OYL and EMC Squared for use around sensitive coastal estuaries. Total petroleum hydrocarbon (oil and grease) levels in runoff from newly applied ROAD OYL pavement were measured at 2 parts per million (ppm) immediately after installation. To provide comparison, the laboratory reported on a study of stormwater pollution from new asphalt pavement in which hydrocarbon levels exceeded a company’s NPDES permit limit of 15 mg/l in six out of seven outfalls. This is not surprising, since the typical oil and grease content in asphalt drops from several hundred thousand ppm (greater than 20%) when new to about 30,000 ppm (3%) after aging for a period of years, according to Analytical Test- ing Laboratory. Resin Pavement samples (as opposed to runoff) were also tested for 63 volatile or- ganics (VOCs), 16 polynuclear aromatic hydrocarbons (PAHs), and 9 metals. None of these regulated substances were found (i.e., the levels of all were below the detec- tion limits of the measurement apparatus). Newly applied asphalt, on the other hand, frequently contains measurable levels of many regulated VOCs and PAHs, according to the laboratory. EBN mixed up a small sample batch of ROAD OYL Resin Pavement using crushed brick and sand. We found the batch easy to mix and work with; it had a mild, nonde- script smell. The three resultant samples were a deep brick color. Two samples had inadequate fines and did not hold together well, while added sand in the third resulted in a very strong block. This supports the manufacturer’s recommendation to produce and test sample batches to achieve the right mix. 20.7Road Engineering Gary Ruyle, ASLA of the Schmidt Design Group in San Diego is very enthusiastic about Resin Pavement after using it on two projects. “It’s great,” he told EBN. They used Resin Pavement most recently for a 1.5-mile (2.4 km) long and 6-foot (1.8 m) wide Silver Strand: Nature’s Bridge Trail in Coronado, California -- along a spit of land that separates San Diego Bay from the ocean. Ruyle wanted a natural-looking surface that would be ADA- (Americans with Disabilities Act-) accessible. Learning from an earlier project using Resin Pavement, he designed this trail wide enough to bring in larger equipment needed to firmly compact the surface, and he specified steel edging that allowed compacting with a roller right up to the trail edges. “We got really good compaction at the edges -- I recommend that,” he said. John Aranson, who manages trails for Marin County, California (north of San Fran- cisco) has used ROAD OYL on four or five projects. “I am very very pleased with the product,” he told EBN. On one of these projects -- a section of horse trail built six or seven years ago through a wet area -- he reported that it has held up extremely well. “It still looks as if I put it down last year,” he said. The environmental features were what first attracted him to ROAD OYL. “I didn’t want to put down something that would be harmful to the environment.” He said that the biggest obstacle to him is the acces- sibility of his projects for the paving equipment needed for proper installation. There is also some resistance from paving companies that worry about the ROAD OYL binding up their equipment -- it should be washed off before drying. Achieving success with Resin Pavement isn’t automatic. At the new Adam Joseph Lewis Center for Environmental Studies at Oberlin College, designed by William Mc- Donough + Partners, the Resin Pavement system did not achieve full strength. Ac- cording to Martin Troutman of the landscape architecture firm Andropogon Associates, who did the landscape design, the problem was apparently an inadequate fraction of fines in the aggregate mix. Mel Lee of Soil Stabilization Products said that “this is a case where the contractor has attempted to ignore project construction specifica- tions.” At the Glen Canyon National Recreation Area, Resin Pavement was used four years ago to build a trail that is totally submerged by flooding several months out of the year. This year the trail had to be replaced, according to Roads and Trails Foreman Pete Howard. They are trying out two different materials. Information about the project that Soil Stabilization Products has published notes that the aggregate mix included 60% native red clayey sand. Commenting on this failure, Mel Lee noted that “the impor- tance of aggregate selection and its fundamental role in the durability of a pavement just can’t be emphasized enough.” As for cost, Soil Stabilization Products Company president Bob Randolph told EBN that the installed cost of Resin Pavement is “normally somewhat more than hot-mix asphalt pavement and less than concrete pavement.” Gary Ruyle concurs that the pavement wasn’t inexpensive on the Nature’s Bridge Trail. “It certainly cost as much 20.8 Bar Slash X Ranch LLC - Annexation and Stage Road PUD/Subdivision: Final Submission as asphalt,” he said, “but if you did a life-cycle cost [analysis] on it, you’d probably be happy.” 20.9Road Engineering MATERIAL SAFETY DATA SHEET Manufacturer PROCESS CHEMICALS, LLC ARR-MAZ PRODUCTS, LP Division 621 Snively Avenue Winter Haven, Fl 33880 Emergency Phone Number 863-293-7884 PRODUCT INFORMATION Trade Name: Road Oyl Chemical Family:Mixture HMIS RATING:Health Hazard 1 Slight Flammability Hazard 0 Minimal Reactivity Hazard 0 Minimal DOT Shipping Classification This product is not regulated when shipped domestically by land.
