| Abstract: | Semi-rigid basic material has become the main form of basic level structure for highways, but the decrepitude of the freeze strength has been the important factor influencing the road quality. As to Heilongjiang region, it selects the suitable cement content for decreasing strength decrepitude on road base in the applicative period through the test of cement stabilized sand-gravel material. By means of various low temperature test methods, it can raise the quality that the road is used and prolongs life-span of road service. |
