随着高等级公路的大力发展,道路交通量迅速增加,车辆大型化、超载严重等问题随之出现。我国为了缓解在重载交通下的动水压力问题,开始研究使用和推广沥青稳定碎石为代表的柔性基层,文章主要介绍了级配沥青稳定碎石基层的特点、适用范围、工艺原理及施工工艺。 With the vigorous development of high-grade highways, the traffic volume of the roads has rapidly increased, problems such as large-scale vehicles and serious overloading have appeared. In order to alleviate the hydrodynamic pressure under heavy traffic, China began to study the use and promotion of asphalt stabilized gravel as the representative of the flexible grass-roots level. The article mainly introduced the characteristics, applicable scope, process principle and construction of gradation asphalt stabilized macadam base Process.
