Abstract

FWD testing are currently used and studied worldwide. This is a non-destructive testing, used to evaluate the load capacity of a pavement structure. Results obtained from experiments are the elastic modulus of pavement structure layers, estimated based on deflection surface under a load caused by falling heavy object. Domestically, several researchers remain skeptical about the authenticity of the results predicted from FWD. This study refers to the process of comparing granular modulus of pavement base layers obtained from FWD testing, determined by BISAR-GAs, with some other experiments as Seismic Pavement Analyzer (SPA), Dynamic Cone Penetration (DCP), and in Laboratory (LAB).
