ABSTRACT:
An asphalt cement mixture is disclosed. The mixture has improved antistripping properties due to the inclusion therein of a minor amount of an antistripping agent produced by the condensation reaction of an amine, an aldehyde or aldehyde reaction synthon an alkylated phenol. The antistripping agent is preferably present in the asphalt cement in an amount of from about 0.25% to about 1% by weight based on the weight of the asphalt cement. The asphalt cement is combined with an aggregate to form a concrete and paved onto a road surface to provide a paved surface with improved durability.
