Concrete Pavements Under Container Stackings

Contact pressures produced by container stackings in concrete pavements are very high. Theoretically, slab stresses widely overcome the flexural strength of concrete. However, in real pavements functional conditions are not affected as it is observed. Therefore, what is really happening should be analyzed. A full-scale test was made in summer of 1996 in the Port of Valencia (Mediterranean Coast) in order to measure real pressures, how loading is transferred to the pavement and which are the induced stresses. The test and the theoretycal model used are described. Obtained results are commented and useful conclusions are drawn in order to improve the structural design of concrete pavements in ports.
