The main object of this study is to estimate the bearing capacity of subgrade and base course using the FWD (Falling Weight Deflectometer) and HFWD (Handy type of FWD). Investigations were carried out on newly-established road pavement at Kitakyushu city. The study has indicated that it is possible to be evaluated the bearing capacity K30-value by the KKWDvalue, KHFWD-value and Young's modulus E.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
