公路水稳基层快速修补技术的应用

Application of Rapid Repair Technology for Expressway Cement-stabilized Base

文章进行了不同养生温度、不同养生时间条件下的水稳试件抗压强度试验,得到了不同设计强度下水稳基层养生时间与养生温度的时温曲线,建议根据时温曲线进行工程施工。结果表明:面层紧跟基层施工的养生方式能提供较好的高温养生条件,达到快速修补的目的。

The compression strength of cement-stabilized specimen are tested under the conditions of different curing time and temperature, the curves of curing time and temperature in different design strength of cement-stabilized base are got. It is suggestted that the pavement should be paved according to the curve. The results show that the curing method of surface course construction closely follow base could provide high temperature curing condition and achieve rapid repair purpose.
