Modified asphalt having good adhesion

Abstract

Abstract PURPOSE:To provide the title asphalt which has good adhesion and is free from flowing, peeling and wearing in the winter, by adding a small quantity of a silande compd. to a modified asphalt. CONSTITUTION:0.1-5pts.wt. silane compd. such as methyltrimethoxysilane is added to 95-99.9pts.wt. modified asphalt obtd. by mixing 1-20pts.wt. thermoplastic resin and/or rubber (e.g. an ethylen/ethyl acrylate copolymer having an ethyl acrylate content of 5-50wt% and a melt index of 0.5-50) with 50- 95pts.wt. asphalt (e.g. paving asphalt obtd. by adding an appropriate quantity of a softener to straight asphalt). The mixing is conducted by heating at 100- 250 deg.C.
