应用Superpave体积设计法设计冷再生沥青混合料

Designing Cold Recycled Asphalt Mixtures with Superpave Volumetric Design Method

旧沥青路面的再生利用是我国公路建设即将面临的重要课题,其中冷法再生是一种重要方法。本文针对乳化沥青冷再生沥青混合料的设计提出了修正Superpave设计法,经室内试验验证,证明该法取得了较好的效果。

Recycling of asphalt pavements is one of the most urgent task to be solved for highways building in our country.As a result,cold recycling is one of the most important methods.Based on the analysis of cold recycled asphalt mixes with emulsified asphalt,modified superpave method to design this kind of mixtures was proposed in this paper.We have got better results with this method through test for the designed mixture indoor.
