CHEMICALLY STABILIZED ASPHALT RUBBER COMPOSITIONS AND A MECHANOCHEMICAL METHOD FOR PREPARING THE SAME

摘要

The invention is a chemically stabilized asphalt rubber composition and a mechanochemical method for preparing the said compositions. The chemically stabilized and modified crumb rubber asphalt composition containing virgin asphalts, crumb rubber and an additive package consisting of a dispersant and antisettling, a cross-linking additive with olefinic double bounds, a flow modifier and in case of necessity one or more other antioxidant, anticorrosion additives, where the composition is made of 55-95 w/w% asphalt, 3-40 w/w% crumb rubber from scrap tyres, and 0,04-5 w/w% multifunctional additive package, which is a mixture of multifunctional Components (0,03-4 w/w%) 'A', (0,01-4 w/w%) 'B', and if necessary Component 'C' (0-2 w/w%) of complementary effects.
