摘要
排水沥青路面结构可提高路面安全性、环境友好型等道路新功能,即将成为我国第四代功能性沥青路面发展的重要方向。以宁靖盐高速公路运营13年的罩面工程为依托,结合旧路面残余寿命评估、级配优化与加速加载验证,并在施工工艺优化和环境功能评估等方面进行研究,为旧路面工程中应用排水沥青路面技术提供工程实践支持。
Drainage asphalt pavement structure can improve road safety, environment-friendliness and other new road functions,and it will become the important direction of the fourth generation of functional development of the asphalt pavement highway in China. Based on the overlay project of Ningjingyan highway, which has been in operation for 13 years, and combined with residual life assessment of the old pavement,grading optimization and accelerated verification,the aspects of construction technological optimization and environmental assessment are studied for practical support.
