Behavior of Joint Panel of Precast Prestressed Concrete Pavement System with Different Design Details

From the extensive review of literature on existing precast prestressed concrete pavement (PPCP) systems, an innovative PPCP system has been developed. After the analysis and design, the sample system has been built and experimented under service loads and the defects of the system has been noted. Further study has been done to improve the performance of the defects. The appeared cracks around post-tensioning pockets was a crucial problem which needed to be solved in order to satisfy the service life of the system without any doubt. In this paper, different shape and arrangement of the post-tensioning pockets in the joint panel has been designed and analysed in order to find best performance for the system.
