Predicting resilient modulus of flexible pavement foundation using extreme gradient boosting based optimised models
Resilient modulus ( $M_R$ ) plays the most critical role in the evaluation and design of flexible pavement foundations. $M_R$ is utilised as the principal parameter for representing stiffness and behaviour of flexible pavement foundation in experimental and semi-empirical approaches. To determine $M_R$ , cyclic triaxial compressive experiments under different confining pressures and deviatoric stresses are needed. However, such experiments are costly and time-consuming. In the present study, an extreme gradient boosting-based ( $XGB$ ) model is presented for predicting the resilient modulus of flexible pavement foundations. The model is optimised using four different optimisation methods (particle swarm optimisation ( $PSO$ ), social spider optimisation ( $SSO$ ), sine cosine algorithm ( $SCA$ ), and multi-verse optimisation ( $MVO$ )) and a database collected from previously published technical literature. The outcomes present that all developed designs have good workability in estimating the $M_R$ of flexible pavement foundation, but the $PSO-XGB$ models have the best prediction accuracy considering both training and testing datasets.
