摘要
将废橡胶粉加入到基质沥青中,通过物理和化学反应制备出橡胶沥青,其技术性能指标优良。安徽省六武高速公路中面层采用AR-AC20橡胶沥青混合料,并优化了配合比设计,加强了施工质量控制,实践表明,AR-AC20路面表现出良好的路用性能,可为其他类似工程项目提供借鉴。
Asphalt rubber will be produced by adding crumb rubber into the base asphalt particles through physical and chemical processing. The performance indexes of the asphalt have been tested, and the results indicate that asphalt plastic-rubber has good performance. AR-AC20 was adopt- ed in Lu＇an-Wuhan Expressway. AR-AC20 demonstrates good serviceability by optimizing the gradation design of mixture and strengthening the construction control, which would offer useful reference for similar projects.
