不同种类再生剂对再生沥青性能的影响

Effect of Different Kinds of Regenerators on the Performance of Recycled Asphalt

沥青路面因为其特有的技术和性能优势,在我国公路路面结构中占据了越来越重要的地位。但是沥青病害现象也越来越明显。若能实现沥青的再生利用具有很好的现实意义。针对国内市场上常用的四种再生剂,文章研究了再生剂的基本成分,性能以及渗透均匀性对混合料路用性能的影响,比较了再生剂的扩散性能,对生产过程使用再生剂具有指导意义。

Asphalt pavement plays an increasingly important role in highway pavement structure in China because of its unique technical and performance advantages. But the phenomenon of asphalt disease is more and more obvious. It is of great practical significance to realize the recycling of asphalt. In this paper, the effects of the basic components, properties and permeability uniformity of the regenerant on the road performance of the mixture were studied. The diffusion performance of the regenerant was compared, and the regeneration agent was instructed in the production process.
