用于应力吸收层的混合料设计与性能试验

Mixture Design and Performance Test for Stress-absorbing Interlayer

在应力吸收层参数对其防反性能分析的基础上,采用AC—10级配设计橡胶沥青应力吸收层,相比单一粒径橡胶沥青应力吸收层,该级配不仅发挥了橡胶沥青黏度高、弹性大的优势,级配的设计更增加了应力吸收层的防水和黏结效果。考虑到STRATA应力吸收层良好的防反效果,同时对其加以设计比较,还就橡胶沥青混合料的黏结性和模量进行了实验研究,提出了适合于应力吸收层的材料和工艺设计。

On the basic of anti-crack performance analysis for stress-absorbing interlayer parameter,AC-10 asphalt rubber mixture was selected as such material.Comparing with sole particle size grade,it not only takes advantage of rubber-asphalt's high viscosity and high elasticity,but also enhances the performance of waterproof and adhesive bonding.This material was compared with STRATA to verify its anti-cracking performance.Finally this paper researched the cohesiveness and modulus of rubber-asphalt mixture,and gave standard and technology for stress-absorbing material design.
