Mechanistic-empirical Design of Perpetual Road Pavement Using Strain-based Design Approach

Present paper deals with the development of a Mechanistic-Empirical model strain-based design perpetual road pavement using Odemark's principle. The bituminous which can withstand minimum traffic 300 msa has been classified as in this paper. considered three-layered system top layer mix followed by unbound granular materials rest on soil subgrade. constituent thickness determined limiting radial tensile strain at bottom against fatigue and vertical compressive subgrade rutting. allowable rutting used present analysis from mechanistic-empirical correlations recommended IRC:37-2018. section transformed into homogeneous method for application Boussinesq's theory. To validate pavement, different interfaces was compared IITPAVE software, shows is safe but marginally fails under fatigue. Moreover, conventional obtained IRC:37-2018 were method, reasonably good convergence. It found that layered seems to be more sensitive than In backdrop, modified values have pavement.
