Abstract

The invention provides modified asphalt which comprises, by weight, 91-95 parts of matrix asphalt, 2.5-4.5 parts of SBS asphalt modifiers, 0.1-0.3 part of epoxy resin, 1-2 parts of sulfonated phenolicresin, 0.5-1.2 parts of carrageenan, 0.1-1 part of aluminum-magnesium silicate, 0.2-0.5 part of vulcanizing agents and 0.1-0.5 part of stabilizers WD-5. The modified asphalt is excellent in stabilityand cannot be separated in long-term storage.

Description

technical field [0001] The invention relates to the technical field of asphalt processing, in particular to a modified asphalt. Background technique [0002] Asphalt is a dark brown complex mixture composed of hydrocarbons of different molecular weights and their non-metallic derivatives. It is a kind of high-viscosity organic liquid. It is liquid with a black surface and is soluble in carbon disulfide. Asphalt can be divided into coal tar pitch, petroleum pitch and natural pitch. Among them, coal tar pitch is a by-product of coking, petroleum pitch is the residue after crude oil distillation, and natural pitch is stored underground, and some form ore layers or accumulate on the surface of the earth's crust. Asphalt is mainly used in coatings, plastics, rubber and other industries as well as paving roads. [0003] Generally, in order to enhance the overall performance of asphalt materials, it is necessary to add SBS asphalt modifier to the base asphalt to obtain a modified...
