Description

technical field [0001] The invention relates to the technical field of asphalt, in particular to a high-temperature-resistant and high-viscosity asphalt modified material, modified asphalt and a preparation method. Background technique [0002] Asphalt is a black-brown complex mixture composed of hydrocarbons of different molecular weights and their non-metallic derivatives. It has good adhesion, insulation, heat insulation and moisture-proof, anti-seepage, waterproof, anti-corrosion, anti-rust and other properties. , can be used for road laying, house waterproof layer, cold storage insulation layer, railway anticorrosion, underground pipeline rust prevention, etc. However, the ductility, softening point and viscosity toughness of the commonly used base asphalt are low, which is not conducive to its wide application. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a modified asphalt material for the deficiencies of the prior art, and t...
