Description

technical field [0001] The invention belongs to the technical field of asphalt materials, in particular to a modified polyurethane asphalt material. Background technique [0002] Petroleum asphalt has good adhesion, aging resistance and waterproof ability, and has been widely used as road construction, waterproof and sealing materials for a long time. It is one of the most widely used materials in waterproof and anti-seepage projects at home and abroad because of the advantages of easy-to-obtain raw materials and low prices for waterproofing projects; but asphalt, like petroleum, is a complex organic mixture without fixed chemical composition and physical properties. constant, and many oil minerals form a continuous series in transitional form. This brings many difficulties to classification and identification. [0003] Polyurethane asphalt has a wide range of applications, long life, weather resistance, deformation resistance, high tensile strength, high elongation, stron...
