摘要
通过分析粉煤灰的物理成分、路用性能,指出粉煤灰是一种匀质级配材料,在软基中可以减轻土基压力,提高路堤水稳性能;在路面中使用可以提高面层的刚度、强度和整体稳定性,在公路工程中具有广阔的应用前景。
By analyzing the physical components of fly ash, road performance, and pointed out that fly ash is a homogeneous gradation material. In the soft ground it can reduce the pressure and improve water stability; in the use of the road surface it can be improve the stiffness, strength and overall stability; in highway engineering it has broad prospects for development.
