The concept of using U-shaped Concrete Panel (USCP) is expected to be a solution in strengthening low bearing capacity subgrade, used as foundation for rural road. The objective of this paper is to present the experimental feasibility in designing and testing of the USCP. The USCP has a shape of a panel with webs coupled at both end. The shape is designed to have optimum flexural strength as well as to overcome heaving of the ground. This USCP also should give an interlocking effect to the soil in contact with the USCP. The design of the shape is determined by the concept of U-shaped drain and shear failure of soil. This USCP further give advantage in providing strength to the low bearing capacity subgrade. Experimental tests included to determine the engineering properties of the USCP are the flexural strength test, dropweight impact test, and dynamic load test. In this study, this USCP is aimed to be able to provide additional strength to the subgrade without disturbing the native soil.References
