[Abstract] cement rubble of the grass-roots level as a good semi-rigid material, with the overall strong, high-capacity, stiffness, water stable, and construction technology to facilitate more economic and other characteristics of China's expressways and high - Grade highways are widely used. Semi-rigid surface of the bearing capacity depends on the semi-rigid and semi-rigid at the end of the grass-roots level mixture of strength and thickness. The two semi-rigid structure of the road is the key level, cement stability in the rubble of the road to have a direct impact on the use of performance, cement rubble strength of factors in cement, aggregates (aggregate) level and allocation Construction site conditions, the paper is used orthogonal test on the design of the cement rubble of the mix, and the very poor through the analysis of variance were identified cement content, <0.075 mm powder content,> 4.75 mm coarse aggregate content And the largest particle size, and other f
