HMA路用性能影响因素综述

The Factors Review of HMA Pavement Performance

本文通过分析HMA(Hot Mix Asphalt,HMA)路面存在的早期损坏的原因及影响性能的因素,从路面结构设计,材料选择和施工作业控制等方面探讨改善路面使用性能的途径和方法。另外还针对高性能HMA路面的特殊性,总结了保证施工质量和避免引道沉陷跳车等改善路面性能的相应措施。

The early damage causes that the HMA(Hot Mix Asphalt HMA) pavement existed and factors that affected the pavement performance were analyzed in this paper. The ways and means were studied to improve the pavement performance from many aspects such as the pavement structure design, the material selection and the construction job. In addition, the appropriate measures that could guarantee the construction quality and avoid the approach roads subsidence of jumping cars were summed up to improve the road performance for the particularity high performance of HMA pavement.
