水泥对半刚性基层路用性能的影响研究

Research on the performance of the semi-rigid roadbase

本课题选择到了水泥稳定碎石、石灰粉煤灰稳定碎石和在石灰粉煤灰稳定碎石掺水泥等3种基层类型,从强度、模量、水稳定性、抗冲刷性、抗疲劳特性的角度,综合分析它们的路用性能及力学性,从它们的差异和变化探讨水泥对半刚性基层的影响.

The paper chooses three kinds of semi-rigid roadbase,which are lime-fiyash aggregate and cement aggregate and lime-fiyash aggregate added cement as usral, analyses systematically a series of the performance on their intensity and their stabilization with watering and freezing and the scour of water and fatigue performance etc, and the influence on the semi-rigid roadbase with cement is discussed accroding to the difference and variety among them.
