STRENGTHENING OF EXISTING FLEXIBLE PAVEMENTS WITH CONCRETE IN THE CENTRAL REGION OF FRANCE

RENFORCEMENTS EN BETON HYDRAULIQUE DE CHAUSSEES SOUPLES DANS LA REGION CENTRE

This article describes 5 sites where flexible pavements have been strengthened with concrete and reviews their behaviour after 2 to 4 years of traffic. Two pavements (the least and the most heavily trafficked) and the second and fifth built show no deterioration. Gaps observed on the longitudinal joint, especially in two pavements, are due to the exceptional drought of 1976. Indeed, longitudinal cracks 10 to 30 mm wide caused by clay shrinkage and settlement of the slab were observed together with gaps from 10 to 100 mm on A number of flexible pavements in the region. These defects are not attributable to rigid pavement techniques; because repairs are costly, unsightly and difficult, special attention will be paid in the future during geological studies to the localization of zones subject to deformation and to the setting up of preventive measures.
