U.S. Cold Patch

Enviromental Criteria	U.S. Cold Patch®	Cutback Asphalt
1. Lowest harmful emissions ^{Lowest VOCs No hazardous pollutants No heated asphalt fumes No kerosene or diesel fumes No manufacturing plant emissions}
2. Lowest life-cycle energy inputs ^{No quarrying, transportation, and crushing of rock No refining or heating of virgin asphalt Produced at ambient temperature without combustion}
3. Highest post-consumer recycled content ^{asphalt: 100% recycled aggregate: 100% recycled}
4. 100% recyclable

U.S. Cold Patch® is made from nearly 100% post-consumer recycled materials, without light distillate petroleum solvents, such as kerosene or diesel, which are found in traditional “cutback” asphalt patching products. These solvents contain significant amounts of VOCs (volatile organic compounds), which combine with nitrogen oxides in the presence of sunlight to form ozone. To reduce smog formation, many states and regions now ban the sale and use of cutback asphalt during the ozone season, late spring to early fall.

U.S. Cold Patch® is the only cold asphalt patching product that has been evaluated and certified as environmentally preferable by Scientific Certifications Systems for the Home Depot’s prestigious Eco-Option program.

Environmental Criteria Notes:

1. Lowest harmful emissions

Lowest VOCs: Independent testing (Washington State University, 2006) reported the total organic carbon content of U.S. Cold Patch® to be less than 2 percent that of the most commonly used cutback asphalt. In independent testing (ASTM D244 /D6997) of three leading bagged asphalt products in 2009, only U.S. Cold Patch®’s VOC content was low enough to pass stringent the new air regulation in New Jersey (NJAC 7:27-16.19a(2)), aimed at reducing VOC emissions by banning cutback asphalt. (One regional brand of biodiesel cutback also has low VOCs.)
No hazardous pollutants: Among the hazardous pollutants emitted from cutback asphalt of most concern to the EPA are toluene, ethylbenzene, and xylenes. Independent tests confirms that U.S. Cold Patch® contains none of these pollutants. (One regional brand of biodiesel cutback also does not contain these three pollutants.)
No heated asphalt fumes: No asphalt is heated during the production of U.S. Cold Patch®.
No kerosene or diesel fumes: No light distillate petroleum solvents are used in the manufacture of U.S. Cold Patch®. (One regional brand of biodiesel cutback also does not contain light distillate petroleum solvents.)
No manufacturing plant CO₂ emissions: Cutback asphalt products require heat to dry the aggregate and heat the cutback liquid (asphalt & solvent) prior to mixing. U.S. Cold Patch® is manufactured at ambient temperature.

2. Lowest life-cycle energy inputs

No quarrying, transportation, and crushing of rock: U.S. Cold Patch® is made from recycled asphalt pavement (RAP), not virgin aggregate. RAP is removed from roadways during repaving. Crushing and processing RAP consumes far less energy that quarrying, crushing, and processing new rock.
No refining or heating of virgin asphalt: U.S. Cold Patch® is made without virgin asphalt.
Produced at ambient temperature without combustion: Cutback asphalts require heat to dry the aggregate and heat the cutback liquid prior to mixing. U.S. Cold Patch® is manufactured at ambient temperature.

3. Highest post-consumer recycled content

asphalt: 100% recycled.
aggregate: 100% recycled.

U.S. Cold Patch® is made without virgin asphalt or virgin aggregate. (Two regional cutback brands use RAP in place of virgin aggregate.)

4. 100% recyclable

Road repairs and patches can be recycled as RAP when hot mix asphalt pavements are resurfaced.

Simply THE BEST asphalt patch.
