Abstract

The invention relates to the technical field of building materials for road engineering, in particular to a preparation method of an environment-friendly asphalt modifier. The preparation method of the environment-friendly asphalt modifier comprises the steps of filling the asphalt mixture modifier into a hot-melt packaging film and sealing and wrapping. The environment-friendly asphalt modifier prepared by the preparation method eliminates the problems of existing solid asphalt powders such as environmental pollution, influence on construction efficiency and poor environmental adaptability of modified asphalt, and has simple production, low cost, excellent modification effect and strong adaptability , Environmental performance is remarkable.

Description

Technical field [0001] The present invention relates to road construction materials engineering technology, and particularly relates to an environmentally friendly method for preparing asphalt modifier. Background technique [0002] As an important part of the infrastructure of roads, has been attached great importance to the national and local governments, asphalt concrete surface because of its smooth, seamless, driving comfort, less vibration, low noise, wear-resistant, easy to clean, no dust, short construction period , easy maintenance and repair can be recycled, a suitable construction stage, etc., as the main material of the type of road surface layer. [0003] With the rapid development of the transport sector, service level requirements and road pavement adaptive put forward higher requirements. To meet the above requirements, such as SBS, SBR, powder, PE, natural asphalt, asphalt modifier develop rapidly. Natural asphalt, for example, compared to other modifiers SBS and...
