高等级沥青路面柔性基层的施工工艺与质量控制

Construction Technology and Quality Control for High-level Asphalt Pavement with Flexible Base

由于交通量的快速增长和轴载的加重,沥青路面普遍出现了抗车辙能力不足和耐久性较差等质量问题。沥青稳定碎石基层具有良好的抵抗反射裂缝和抗车辙能力,可有效解决以上问题。本文结合工程实例,对各种施工机械组合的压实效果进行比较,同时对沥青稳定碎石基层的施工控制进行了分析。

With the increase of traffic volume and axial load, quality problems such as deficiency of rutting resistance, poor durability appear generally on asphalt pavement. Those problems can be solved by choosing asphalt treated base which possesses good resistance ability of reflection crack and rutting. In combination with actual project, the compaction effects with different construction machinery combinations are compared, and construction control for asphalt treated base is analyzed.
