Abstract

The purpose of this study is to develop the nomographs for conventional flexible pavement (CFP) design based on a mechanistic-empirical approach. An updated resilient modulus (RM) test method proposed by AASHTO in 1992 was utilized to characterize the granular base materials. MICH-PAVE, a finite element (FE) structural analysis program, was employed to establish the algorithms for prediction of structural responses. The algorithms developed were based on a comprehensive FE analysis from MICH-PAVE with 600 different cases. The design AC thickness requirement from this study was compared to the two procedures (AI, AASHTO). It was found that the nomographs developed in this study gave the intermediate results, while the AASHTO procedure yielded the least conservative result. Also, it was reconfirmed that the AI method yields the conservative results for higher levels of ESAL.
