随着半刚性基层沥青路面的大量使用,路面出现的裂缝、车辙、坑洞等问题也越来越普遍。级配碎石层具有良好的排水性能、隔离反射裂缝的功能,有利于减少路面的病害。结合项目所在地的自然条件,按照专项设计出的骨架密实型级配碎石基层的技术要求,对骨架密实级配碎石配合比设计、施工质量控制及应用前景进行了研究。 With the extensive use of semi-rigid base asphalt pavement, the cracks, ruts, potholes and other problems appearing on the pavement are more and more common. Graded crushed stone layer has good drainage performance, the function of isolated reflective cracks, help to reduce the road disease. Combined with the natural conditions of the project site, according to the special design of the skeleton compact graded crushed stone base technical requirements, the design of the solid aggregate gradation gravel mix, construction quality control and application prospects were studied.
