摘要
随着我国各地区交通基础设施的不断完善,人们的出行习惯发生了很大的改变,越来越多的人选择将高速公路作为出行道路,既能有效节省旅途过程中耗费的时间,又使得出行更加便利安全。现代高速公路基层大多为水泥稳定碎石基层,原材料由水泥、碎石组成,是一种半刚性基层。这种类型的基层具有性能稳定、承载能力强、施工进度快、成本廉价等优点,受到施工部门的青睐,但同样也存在着较为明显的缺陷。由水泥碎石制成的基层很容易在施工过程中或投入使用后出现裂缝,严重影响高速公路成品质量和使用寿命。因此如何做好水泥稳定碎石基层裂缝控制工作是当下高速公路工程施工企业的研究热点。阐述了高速公路水泥稳定碎石基层裂缝产生的原因,并提出一些裂缝控制的有效措施,为相关研究提供参考。
With the continuous improvement of transportation infrastructure in various regions of China,people’s travel habits have changed greatly.More and more people choose expressway as the travel road,which can not only eff ectively save the time spent in the journey,but also make the travel more convenient and safe.The base course of modern expressway is mostly cement stabilized macadam base course.The raw materials are composed of cement and macadam,which is a semi-rigid base course.This type of base has the advantages of stable performance,strong bearing capacity,fast construction progress and low cost.It is favored by the construction department,but it also has obvious defects.The base made of cement crushed stone is easy to crack during construction or after putting into use,which seriously aff ects the quality and service life of fi nished products of expressway.Therefore,how to control the cracks in cement stabilized macadam base is a hot research topic for highway engineering construction enterprises.Based on this,this paper expounds the causes of cracks in cement stabilized macadam base of expressway,and puts forward some eff ective measures for crack control,hoping to give relevant people some reference.
