近年来,水泥稳定碎石基层已成为高速公路的主要结构形式,基层作为路面主要承重层,它的质量优劣直接影响到道路建成通车后的路用性能及使用寿命。水稳层大厚度一次性摊铺碾压成形,基层将形成一个整体的板块结构,相对于2次分层摊铺来说,其抗拉伸,抗冲击强度可以显著提高,并可以有效地避免和推迟早期路面的下沉、凹陷、龟裂脱落、坑洞等病害的产生。对于提高公路路面质量,延长公路寿命有重大的意义。
In recent years, the basic layer of cement stabilized macadam has become the main structure of expressway. As the main bearing layer of the pavement, the quality of the cement stabilized macadam directly affects the road performance and service life after the completion of the road. Water Stabilized Large thickness of a one-time pavement roller forming, the grassroots will form a whole plate structure, relative to the two stratified paving, its tensile strength, impact strength can be significantly improved and can be effectively avoided And delaying the early sinking of the pavement, depression, cracked off, potholes and other diseases. For improving the quality of highway pavement, extending the life of the road is of great significance.
