COMPARING THE PREDICTED ELASTIC MODULUS RESULTS OF GRANULAR MATERIAL OF BASE LAYERS OF A FLEXIBLE PAVEMENTSTRUCTURE FROM FWD TESTING WITH SOME OTHER EXPERIMENTS

FWD testing are currentlyused and studied worldwide. This is a non-destructivetesting, used to evaluate the load capacity of a pavement structure. Results obtainedfrom experiments are the elastic modulus of pavement structure layers, estimated based on deflectionsurface under a load caused byfalling heavy object.Domestically,several researchers remain skeptical about the authenticity of the results predictedfrom FWD. This study refersto the process of comparinggranularmodulus of pavement base layersobtainedfrom FWD testing, determined by BTSAR-GAs, with some other experimentsas Seismic Pavement Analyzer (SPA),Dynamic Cone Penetration (DCP),and in Laboratory (LAB).
