Solid waste rubber powder modified emulsified asphalt for permeable pavement as well as preparation method and application of solid waste rubber powder modified emulsified asphalt

The invention relates to the technical field of modified asphalt, and particularly discloses solid waste rubber powder modified emulsified asphalt for a permeable pavement as well as a preparation method and application of the solid waste rubber powder modified emulsified asphalt. A preparation method of solid waste rubber powder modified emulsified asphalt for a permeable pavement comprises the following steps: S1, taking 70 # matrix asphalt, SBS modified asphalt, solid waste rubber powder, an interface agent, an HVA modifier, N-phenylmaleimide, isostearyl isostearate, lignocellulose, mica powder, nano-zinc oxide and glass fibers in parts by weight for later use; s2, mixing and heating the weighed 70 # matrix asphalt and SBS modified asphalt, then adding part of the raw materials, and stirring for 15-20 minutes to obtain a mixture; s3, putting the mixture into a shearing machine, adding the rest raw materials, shearing, and homogenizing in a drying oven. The solid waste rubber powder modified emulsified asph
