本案针对六种典型水泥稳定碎石基层材料在饱水和风干的状态下分别进行的压缩试验发现:水泥稳定碎石基层材料在温度骤然下降或回升时,水泥稳定碎石基层材料的温缩系数和温缩应变急剧增大,而水泥稳定碎石基层材料处于风干状态下的不同温度区域在零下十摄氏度到十摄氏度之间,水泥稳定碎石基层材料在三十摄氏度到四十摄氏度之间和零下二十摄氏度到零下十摄氏度之间的饱水状态下,它的温缩系数和温缩应变比一般风干状态下的大。
In this paper, six kinds of typical cement stabilized gravel base material in the state of full water and air respectively, the compression test found: the basic material of cement stabilized gravel in the sudden drop in temperature or rebound, the cement stabilized macadam base material temperature coefficient of contraction And temperature shrinkage strain increased sharply, while the different regions of the cement stabilized macadam base material in the air-dried state ranged from minus 10 degrees Celsius to ten degrees Celsius, the cement stabilized macadam base material was between thirty degrees Celsius to forty degrees Celsius and Under the condition of full water between minus 20 degrees Celsius and minus 10 degrees Celsius, its temperature coefficient of contraction and temperature shrinkage are larger than those under general air-dry condition.
