黑白复合排水沥青路面技术研究与应用

Technology Research and Application of Black and White Composite Drainage Asphalt Pavement

传统半刚性基层沥青混凝土路面病害严重,车辙、坑槽、拥包、裂缝、唧浆、推移、桥头跳车等困扰着道路工程的高质量发展,并因此造成了道路使用寿命短、后期维护费用高、运营安全性能差等问题。基于此,科研工作者在强基薄面理论指导下,通过优化道路结构组合、改善改性沥青材料、提升施工工艺等方面开展了专项攻关,研发了黑白复合排水沥青路面。论文针对黑白复合排水沥青路面技术,从结构优点、适用性、结构组成,路用性能测试、效益分析等方面进行了详细阐述,为推广长寿命道路结构提供参考。

The traditional semi-rigid base asphalt concrete pavement has serious diseases,rutting,potholes,crowding,cracks,pumping,pushing,bridgehead jumping,etc,plagues the high-quality development of the road,and thus cause the short service life of the road and the high maintenance cost in the later period.Based on this,under the guidance of the theory of strong base and thin surface,scientific researchers have carried out special researches through optimization of road structure combination,improvement of modified asphalt materials,and improvement of construction technology,etc.,and developed black and white composite drainage asphalt for pavement,this article focuses on the black and white conforming drainage asphalt pavement technology in terms of structural advantages,applicability,structure composition,road performance testing,benefit analysis,etc.to provide a reference for the promotion of long-life road structures.
