【 摘 要 】

The compressive strength of cement stabilized gravel is an important parameter of pavement base design and performance evaluation. In this study, the parameter selection of the compressive strength of cement stabilized macadam as the research direction, by collecting both the compressive strength of cement stabilized macadam mixture test data, establishing database of strength, obtain various parameters represent value under different reliability, analysis of specimen forming method, type of aggregate gradation and different influence factors such as the relationship between the compressive strength of the cement stable macadam mixture, using the mathematical regression method, set up under the condition of different curing ages, cement dose the prediction equation of intensity of verified the established logarithm model has higher fitting precision and can provide for pavement structure design and performance forecast value basis.
