The report firstly examines the different types of degradations of concrete pavements distinguishing those which are specific to jointed plain concrete pavements and those which relate to continuously reinforced concrete pavements. For each type of degradation, status indicator, status assessment, causes and remedial measures are presented. The report then describes the maintenance techniques providing precise indications on the products to use and the repair method. Three appendices complete the report: a survey on concrete pavements and the maintenance methods used world-wide; a case study of full-depth replacement of concrete panels with rapid strength concrete in California; a case study of rehabilitation of continuously reinforced concrete with high early strength concrete in South Africa.
