抗裂性水泥稳定碎石基层施工技术研究

Research on Construction Technology of Cement Stabilized Macadam Base with Crack Resistant

随着我国城市地区和高速公路交通量的不断增大,水泥稳定碎石基层由于强度高的特点逐渐成为道路基层材料的主要选择,但水泥稳定基层使用过程中出现的开裂问题一直难以解决。为了研究抗裂性水泥稳定碎石基层施工技术,论文依托项目工程实例,详细介绍了水泥稳定碎石基层的防裂方法和施工关键措施,通过强度试验表明,掺加纤维后道路基层的防裂性能明显提升。

With the increasing traffic volume of urban areas and highways in China,cement stabilized gravel base has gradually become the main choice of road base due to its high strength,but the cracking problem in the use of cement stabilized base has been difficult to solve.In order to study the construction technology of anti-crack cement stabilized macadamia base,this paper introduces the anti-crack method and key construction measures of cement stabilized macadamia base in detail based on the project example.The strength test shows that the anti-crack performance of road base is improved obviously after adding fiber.
