本文通过对水泥稳定碎石基层病害的分析,提出了添加粉煤灰有效改善水泥稳定碎石基层的裂缝,保证路面的使用性能的论点。水泥稳定碎石基层的裂缝是一种常见病害,也是一种不可完全避免的病害,可以采用在水稳碎石混合料中添加粉煤灰改善,也可以从混合料施工过程中细节的控制、后期的养生控制等方面着手,对已产生的裂缝选择合适的材料进行处理,以避免高速公路路面由于裂缝的产生出现早期的损坏,延长路面的使用寿命,提高社会经济效益。
Based on the analysis of the disease of cement stabilized gravel basement, this paper puts forward the argument that adding fly ash can effectively improve the crack of cement stabilized gravel basement and ensure the serviceability of pavement. Crack of cement stabilized gravel base is a common disease, but also a disease that can not be completely avoided, which can be improved by adding fly ash into water-stabilized gravel mixture, and can also be controlled from the details in the construction process of the mixture, The latter part of the regimen control and other aspects of the crack has been selected to choose the right material for processing to avoid highway cracks due to the emergence of early damage to the road to extend the service life of the surface and improve social and economic benefits.
