ABSTRACT:
Novel bituminous coating compositions, bituminous paving compositions and asphaltic compositions are provided herein. These compositions have, in common, from about 0.1% to about 8% by weight of a nitrogen-containing, adhesion-improving, anti-stripping agent therein. Such agent is a sewage sludge-derived oil, or a fraction thereof, which comprises a mixture of saturated aliphatic hydrocarbons, monoaromatic hydrocarbons, diaromatic hydrocarbons, polyaromatic hydrocarbons, polar compounds and basic, pyridine-soluble compounds having the following elemental composition: nitrogen, about 3.4% to about 5% by weight; oxygen, about 5.8% to about 6.9% by weight; sulfur, about 0.3% to about 0.8% by weight; hydrogen, about 9.7% to about 10.4% by weight; and carbon, about 76.9% to about 79.8% by weight.
