Novel bituminous coating compositions, bituminous paving compositions, and asphaltic compositions are provided herein. The essential ingredient in such compositions is an effective amount of a nitrogen-containing, anti-stripping agent comprising a sewage sludge-derived oil, or a fraction thereof, of a particularly recited composition. Such nitrogen-containing anti-stripping agent improves the adhesion of asphalt to aggregate in asphalt concrete, so that the compositions have many improved characteristics.
