Preparing method and application of high-weatherability asphalt cementing material
The invention relates to a preparing method and application of a high-weatherability asphalt pavement cementing material. The preparing method comprises the main steps: processing EPDM waste rubber at a high temperature of 280-350 DEG C by a high temperature cracking device, allowing the EPDM waste rubber to be subjected to shallow cracking into viscous low-viscosity rubber, then adding into heavy-duty asphalt according to a ratio of 30-60%, stirring, and thus obtaining the weatherability modified asphalt cementing material, wherein the durability of an asphalt pavement can be prominently improved. The prepared weather-proof asphalt pavement cementing material has the characteristics of high weatherability, easy construction, environmental protection, safety and the like, has good performance of high temperature and low temperature, and has good economic and environmental benefits.
