ABSTRACT:
An odor-free hot-mix asphalt composition consists essentially of liquid asphalt, or a hot-mix asphalt or a hot mix, cold lay asphalt, or a rubberized hot mix asphalt or a hot mix asphalt with added latex, containing an effective amount of an additive comprising a citrus terpene (4-isopropyl 1-methylcyclohexene) D-limonene mixed with a vegetable oil such as cottonseed oil, soya oil, rapeseed (canola) oil, peanut oil, corn oil, sunflower oil, palm oil, coconut oil, and palm kernel oil. etc. and an effective amount of a silicone oil dispersant. A preferred additive composition consists essentially of 10-15 parts citrus terpene (D-limonene) and 85-90 parts vegetable oil, and an effective amount up to about 2 parts silicone oil, the parts in the composition totaling 100. When 0.5-1.0 parts of this composition are mixed with 99.0-99.5 parts liquid asphalt the resulting liquid asphalt composition is substantially free of characteristic asphalt odors, and other objectionable odors. When 4-8 parts of the mixture are mixed with 99-96 parts of aggregate, the resulting hot-mix asphalt composition is substantially free of characteristic asphalt odor, and other objectionable odors. The exhaust fumes from a hot-mix asphalt plant are also free of characteristic asphalt odor, and other objectionable odors.
