摘要
针对水泥混凝土路面与路基土永久变形之间的相互关系,从降低路面病害角度出发,分析水泥混凝土路面对路基性能的要求。并通过室内动三轴试验对水泥路面路基永久变形的形成机理和影响因素进行分析,基于NCHRP-37A模型,建立了相应的预估方法,以确定粉质粘土路基永久变形量。
In connection with the relationship between cement concrete pavement and permanent deformation of subgrade soil, the requirement of cement concrete pavement against subgrade performance is analyzed from the view of reducing pavement diseases. Moreover, through indoor dynamic triaxial test, the mechanism forming and the factors influencing permanent deformation of such subgrade are analyzed; and based on NCHRP-37A model, the relevant method for prediction is established to subgrade. confirm the permanent deformation of silty clay
