| Abstract: | 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 |
