Experimental Prestressed Concrete Overlay for Y-Tunnel Access-Road in the City of Amsterdam

摘要

The paper contains a description of the design and construction of an experimental prestressed cement-concrete test-section which was constructed in 1980 to examine the practibility of the application for highway pavements. The test-section consists of 3 slabs, each with a length of 30 m and 7.50 m wide. In order to avoid the stressing actions within the expansion joints the stressing steel is arranged in the diagonal direction. The length was kept reduced in order to keep the expansion joints as simple as possible. The structural design is based on fatigue theory making use of the Palmgren-Miner rule.
