Abstract

The invention relates to the technical field of building materials for road engineering and especially relates to a preparation method for an environment-friendly asphalt modifier. The preparation method for the environment-friendly asphalt modifier comprises the following steps: filling an asphalt modifier into a hot-melt packaging film and then sealing the package. The environment-friendly asphalt modifier prepared according to the preparation method is capable of solving the problems of environmental pollution, influence on construction efficiency and low environmental adaptability of modified asphalt of the present solid asphalt powder. The environment-friendly asphalt modifier is simply manufactured, is low in cost and has excellent modification effect, high adaptability and obvious environmental protection property.

Description

technical field [0001] 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. Background technique [0002] As an important part of infrastructure, highways have been highly valued by the state and local governments. Asphalt concrete has a smooth surface, no joints, comfortable driving, low vibration, low noise, wear resistance, no dust, easy to clean, and short construction period. , easy maintenance, renewable utilization, suitable for phased construction and other advantages, it has become the main material type of road surface in our country. [0003] With the rapid development of the transportation industry, higher requirements are put forward for the service level requirements and road adaptability of the road surface. In order to meet the above requirements, asphalt mixture modifiers such as SBS, SBR, rubber powder, PE, natural asphalt, etc. have been ...
