本文介绍了以废橡胶屑与普通路用沥青按适当比例混合后,可得到一种具有高形变、低模量特性的良好混合沥青,用该材料来修筑表处薄层或隔离层,可有效地减少、甚至消除老路面的反射裂缝。并叙述了几种橡胶沥青薄层的施工方法、对材料的要求及路面结构设计思想。对我们利用橡胶屑改善沥青性能和开展有关这方面的研究工作有一定的参考价值。
This article describes the use of asphalt mixed with waste rubber crumbs in an appropriate ratio to obtain a well-mixed bitumen with high strain and low modulus properties that can be used to build a sheet or barrier on the surface of the watch for effective To reduce or even eliminate the reflection of cracks in the old road. And describes several methods of construction of rubber asphalt thin layer, the material requirements and pavement structure design. For our use of rubber crumbs to improve the performance of asphalt and carry out research work in this area have some reference value.
