Abstract
Preparation of an asphalt composition using an asphalt modifier composition comprising at least one member selected from the group consisting of rubber-base modifiers and resin-base modifiers and a phosphorus compound permits the modifier to be satisfactorily dissolved in asphalt. Further, when paving is conducted by using a composition for paving prepared with such the asphalt composition, the adhesion of asphalt to an aggregate is high, and the resultant pavement has markedly improved in rutting resistance and wearing resistance. Therefore, such the pavement has a prolonged service life.
