水泥粉煤灰稳定碎石在高速公路基层中的应用研究

Application of fly ash cement stabilized gravel in highway subgrade

针对目前我国广泛采用的水泥稳定类材料与二灰稳定类材料在高速公路基层建设中存在的问题,提出采用水泥粉煤灰稳定碎石修筑路面基层。通过对材料强度的影响因素、力学性能、配合比设计方法等方面的研究,为水泥粉煤灰稳定碎石材料的进一步推广与应用提供了可靠的理论依据。

Concerning with the problems about the application of cement hoggin and two-ash hoggin used as roadbase material indoor,this papper carried out the plan of using cement FA-bound hoggin as roadbase and studied its preparation and properties. The studying,especially about the technical requirement,the method to design the proportion and element affecting material＇s performance,is not perfect and sufficient,which is confining the generalization and application of this material.
