BASIC EXAMINATION ABOUT THE DESIGN OF THE HIGH STRENGTH RC PRECAST PAVEMENT SLAB IN AIRPORT

The PC precast slab (PPC) used for airport pavement has a problem in respect of joint system and construction cost. In order to solve these, we has been developed about high strength RC precast slab (HRC) as durable as PPC, and joint system by the cotter joint. By this report, we considered about the design of HRC and the cotter joint used for airport pavement by Westergaard's formula, FEM analysis, and the examination by the specimen. As a result, we obtained the check of appropriation design of slab by allowable stress design of reinforced concrete's theory method and design principle of cotter joint.
