浅谈水泥稳定碎石基层在高速公路中的应用

On the Application of Concrete-bound Base in Expressway

水泥稳定碎石基层,以其水稳性好,早期强度高等优点被应用于高速公路路面基层,起着承重层作用.其质量的保证关键在于材料的质量、配合比的设计,拌和厂的控制,摊铺、碾压及养生过程.

Concrete-bound base has the advantage of good stability and high early strength ;which has been applied in the base of expressway surface, playing the role of load-bearing layer. The key to ensure its quality is the quality of material, the design of mixture ratio, the control of mixing unit, and the process of spreading, rolling and maintaining.
