The road transportation system in China is very huge, which puts forward higher requirements for highway overhaul. The competition of transportation industry becomes more and more fierce with the development of the times. Driven by economic benefits, the overloading and full load of transportation vehicles are very common, which caused serious damage to roads. In order to improve driving environment and enhance the quality of road construction to ensure the safety of vehicle drivers, the construction quality of pavement base has received more attention, which has new requirements for highway construction technology. In the current situation, graded crushed stones are used as the base or subbase of asphalt or cement concrete pavement. Graded crushed stones can adapt to a variety of climate impacts and be applied to different levels of traffic on a well-drained basis. In the rainy area, the application of graded crushed stones can better serve the highway engineering, and the graded crushed stones base construction technology is more and more widely used.%我国公路运输体系非常庞大,这给公路大修工程提出了更高要求,交通运输业随着时代的发展竞争越来越激烈,由于经济利益的驱使,运输车辆超载、满载情况非常普遍,对交通道路造成了较为严重的破坏,交通路面网裂、裂缝等情况频发.为了能够使行车环境得以改善,道路建设质量提升以保障车辆驾驶员安全,路面基层施工质量受到了更多关注与重视,对于公路施工技术有了新的要求.在当前形势下,级配型集料作为沥青或水泥混凝土路面的基层或底基层,级配型集料在排水良好的基础上,能够适应多种气候影响并应用于不同等级交通道路,在潮湿多雨地区,级配型集料的应用能够更好的服务于公路工程,级配型碎石基层施工技术应用越来越广泛.
