| Abstract: | Cement stabilized gravel base has advantages of high strength, low cost and wide material sources, and adapts well to the natural, economic and traffic conditions in Heilongjiang Province. Based on local crude sand gravel in Qiqihar, indoor unconfined compression test, water stability test and frost resistance teat were carried out to analyse strength change laws of cement stabilized sand gravel, and the reasonable proportion for bese course construction was concluded. |
