Abstract

PURPOSE: To simply obtain a modified asphalt with low temp. sensitivity and high softening temp. suitable for pavement, etc., by homegeneously mixing molten straight asphalt with phosphorus pentaoxide and a linear saturated hydrocarbon.
CONSTITUTION: Straight asphalt is fed, heated and molten in a reaction still equipped with a high-speed agitator for emulsification, and then about 1W3wt% phosphorus pentaoxide and about 5W20wt% 40W180C linear saturated hydrocarbon, each based on the asphalt, are added. The purpose modified asphalt is obtd. by homogeneously mixing the asphalt with the phosphorus pentaoxide and linear saturated hydrocarbon by means of high-speed agitation at about 200°C.
