Evaluation and Maintenance of the Concrete Pavements on the Mediterranean Highway

Paper by GRACIANI from ISCR 6th 1990

The Mediterranean Highway has been in service for more than fifteen years, and we can state that the performance of the concrete paving has been overall excellent whether referring to its surface characteristics or its structural characteristics, except for those areas giving support where damage has taken place. The modifications carried out on the original design during the construction of successive sections of the highway (shortening of the slabs, lateral drainage and strengthening of the eroded parts of the foundation), have been most beneficial. A preventive maintenance strategy has been followed, through checks and systematic operations. Also, large maintenance operations have been carried out (slabs replacement, groutings, etc.) on the forementioned damaged zones.
