Subgrade resilient modulus is not only the key parameter of pavement structure design
but also the key parameter of mechanical behavior analysis of pavement structure. In order to grasp the prediction of subgrade resilient modulus
the research progress of subgrade resilient modulus
the characteristics and applicability of the prediction model are systematically reviewed. First of all
through statistical analysis
the prediction model of subgrade resilient modulus is mainly divided into constitutive model
empirical formula and unsaturated soil prediction model considering matrix suction. Secondly
the advantages and disadvantages of each prediction model are analyzed. Finally
according to the characteristics of each prediction model
applicability is analyzed in order to provide basic data for the prediction of resilient modulus of different subgrade conditions.
