PURPOSE: To improve the durability of an asphalt pavement by forming a bituminous additive for a paving body of aliphatic monophosphoric acid ester having a specified range of carbonic number and aliphatic diphosphoric acid ester having a specified range of carbonic number. ;CONSTITUTION: A bituminous additive for a paving body having a drainage or a water permeable function is composed of straight chain or branched chain saturated or unsaturated aliphatic monophosphoric acid ester A having a carbonic number of 16-18 and straight chain or branched chain saturated or unsaturated aliphatic diphosphoric ester B having a carbonic number of 16-18, and A/(A +B)×100(mol%) is made a ratio of composition of 40-95. This additive is made 0.05-5.0weight%, favourably 0.1-3.0weight% of this additive against asphalt used for the paving body having the draining or the water-permeable function and added to heated asphalt. An asphalt paving component is manufactured by kneading the sufficiently mixed asphalt mixture with crushed stones, sand and a filler.;COPYRIGHT: (C)1996,JPO
