粉性土是一种较难压实的土 ,试验证明恰当地使用振动压路机 ,合理地控制含水量可以使其达到规定的压实度。冲击碾对本次试验段粉性土的压实效果不明显。粉性土路基表层铺设低剂量的水泥土补强层可以使土基模量有所提高 ,并使粉性土路基表面的模量及弯沉检测得以实现
Soil is a more difficult to compaction of soil, the test shows that the proper use of vibratory roller, a reasonable control of water content can make it reach the required degree of compaction. Impact crushing on the test section of the compaction effect of soil is not obvious. The laying of low-level cement-soil reinforcing layer on the surface of the powdery soil subgrade can increase the modulus of the soil foundation and make the modulus and deflection detection on the surface of the soil subsided
