Analysis of cement concrete pavement structure using recycled aggregate from construction demolition by Mechanistic - Empirical method

Abstract

This article using software to analyze pavement structure by Mechanistic - empirical method (MEPDG to analyze of cement concrete pavement structure using recycled aggregate from construction waste in Vietnam's climate conditions. In addition, the proposed pavement structure was also analyzed according to TCCS39:2022/TCDBVN to compare the calculation results of the two methods with each other. The cement concrete pavement structure used in this study was referenced from the research results to propose a pavement structure plan using recycled aggregate concrete by Associate Professor, PhD. Nguyen Thanh Sang et al. The analysis results show that the proposed pavement structure satisfies all the calculation criteria of both methods. The MEPDG method also shows that the cement concrete pavement structure using recycled aggregate from construction waste is stable over time, the tested factors have little change over the calculation time of the pavement.
