摘要
针对山区重载干线公路急坡陡弯路段出现的车辙、坑槽等病害问题,借鉴法国高模量沥青混合料设计思路,采用复配调和硬质沥青,设计了具有良好抗水损害、抗车辙性能的高模量沥青混合料,并在遵义某干线公路改造工程中进行了应用。实体工程应用验证结果表明:基于硬质沥青的高模量沥青混合料具有较好的技术经济性,是提升山区类似重载干线公路沥青路面综合使用性能的有效技术途径。
In order to deal with the diseases on the heavy-loaded pavement of trunk highway in mountainous area, such as ruts and pits, another kind of high modulus asphalt mixture with nice water-resisting and anti-rutting property was designed on the basis of composite modified hard asphalt through learning the design idea of French high modulus asphalt mixture. The design was also used in a trunk highway reforms engineering in Zunyi. The results indicated that high modulus asphalt mixture which is on the basis of hard asphalt has its superiority on technological and economic side, and it is a effective technological way to improve the comprehensive performance of the similar heavy-loaded pavement of trunk highway in mountainous area.
