高速公路慢速交通路段沥青混凝土配合比设计

Asphaltum-Concrete Assorted Rate Design for Slow-Speed Traffic Section in Highway

针对慢速车道路段交通荷载的特点,从沥青原材料选择及级配优化设计入手,研究了慢速交通条件下抗车辙沥青混合料的设计方法,并对设计的沥青混合料抗永久变形性能进行分析和评价,提出慢速交通段沥青混合料的设计指标、设计参数。

Aiming at the characteristics of the traffic load on the slow-speed driveway, beginning from choosing asphaltum raw materials and degree-matching optimized design, the research on the design method of anti-track asphaltum mixed materials under the circumstances is made. Analysis and evaluation of the anti-distortion characteristics of the designed asphaltum mixed materials is made too. Design index and parameter of asphaltum mixed materials used in slow-speed traffic section is put forward.
