A good and qualified condition of road infrastructure is a main issue in economic growth in Indonesia. Therefore, the road quality must be able to serve the traffic increase and the pavement structure must be well-designed. In pavement structure, the pavement structure consists of surface layer, subbase or base layer, and subgrade layer. The testing of structural strength is required in evaluating a subbase or base layer. The LWD testing is a tool used to measure the structural strength of a pavement structure system. LWD testing uses the principle of wave theory by dropping some load from particular height is taken by the geophone sensor. The result of LWD is the deflection which is used for measuring elastic modulus applying Boussinesq equation. This tool was used in the base course layer testing in the campus area of Universitas Muhammadiyah Yogyakarta with 16 testing points. In the same testing point, Dynamic Cone Penetrometer (DCP) was conducted. From this testing, the value of CBR (%) and elastic modulus (MPa) obtained from the value of DCPI. The comparison on LWD and DCP results show the both testing produce the similar elastic modulus in which the results obtained have fairly strong correlation value. Thus, the LWD tool can be used for the inspection of structural in the pavement structure
