砂砾石混合料干密度与碾压遍数的关系研究

Relationship Between Dry Density of Sand and Gravel Mixture and Frequency of Rolling

选择试验场地和碾压机具,在试验场地上进行砂砾石混合料路基干密度与碾压遍数的关系试验,并根据试验数据绘制出在各型压路机作用下混合料干密度与碾压遍数的关系曲线,有助于对砂砾石混合料路基干密度与碾压遍数的关系进行深入的分析研究。

Choosing test field and rolling mechines to test the relationship between the dry den- sity of sand and gravel mixture subgrade and the frequency of rolling, and drawing the relation curve of the mixture＇s dry density and the frequency of rolling in the cases of the mixture bears the effect of various types of road roller are helpful for the in-depth study on the relationship between the dry density of sand and gravel mixture subgrade and the frequency of rolling.
