Construction of Prestressed Concrete Pavement Slabs in Osaka City

Abstract

This paper describes the prestressed concrete pavement slabs, 60 m and 40 m in length which were constructed in Osaka City in January of 1958. Prestressing steel was laid in both longitudinally and transversely in the 60 m slab, and diagonally with angles of intersection of about 60 deg. in the 40 m slab. The construction and testing of the pavement slabs are described in detail. The results prove the superior behavior of prestressed slabs, especially in their elastic recovery, and indicate that. such construction could be advantageously utilized in future pavement construction when it becomes economically comparable with other forms of construction.
