Abstract

 In this study, reliability of the base-course thickness design curves in Japan were examined based on bearing capacity research results of an actual size concrete pavement / base course yard constructed in the Public Works Research Institute and the past researches. As the results, it was found that the degree of reliability of design curve of the crusher-run base and the mechanically stabilized base is 80%, 70% respectively. And it was also found that different design curve of cement-treated base would be required for each base course thickness. In addition, based on these results, the design curve of each base course materials considering reliability was proposed in this study.
