CONCRETE PAVEMENTS - CEMENT FOR ROAD CONSTRUCTION CONCRETE - COUVROT EXPERIMENTAL ROAD

CHAUSSEES EN BETON - LES CIMENTS POUR BETONS ROUTIERS - CHAUSSEE EXPERIMENTALE DE COUVROT

THE COUVROT EXPERIMENTAL ROAD IS PART OF A SERIES OF IN-SITU AND LABORATORY STUDIES CARRIED OUT TO DEFINE THE LIMIT CHARACTERISTICS OF CEMENT USED IN ROAD CONSTRUCTION BEFORE UPDATING THE REGULATIONS GOVERNING THE SELECTION OF CEMENT FOR CONCRETE ROADS; THIS UPDATING BECAME NECESSARY AFTER THE ESTABLISHMENT OF NEW STANDARDS FOR CEMENT. DETAILS ARE GIVEN OF THE EXPERIMENTAL PROGRAMME, CEMENT SELECTION, AND PAVEMENT CONSTRUCTION. IN-SITU OBSERVATIONS SHOWED THAT AS REGARDS FRESH CONCRETE CHARACTERISTICS (WORKABILITY, ENTRAINED AIR CONTENT) AND HARDENED CONCRETE CHARACTERISTICS (FLEXURAL AND COMPRESSIVE STRENGTH), THE NATURE OF THE CEMENT USED DOES NOT GIVE RISE TO SPECIAL PROBLEMS. THE FOLLOW-UP STUDY OF THE EVOLUTION IN WEAR AND SKIDDING RESISTANCE OVER MEDIUM AND LONG TERM SHOULD BE UNDERTAKEN. THE RESULTS OF ACCELERATED WEAR TESTS SEEM TO INDICATE THAT THE DIFFERENCES IN BEHAVIOUR UNDER TRAFFIC CONDITIONS ARE NOT VERY MARKED. THE EVOLUTION IN SKIDDING RESISTANCE WILL BE MAINLY INFLUENCED BY THE BEHAVIOUR OF THE SURFACE TREATMENT SELECTED. FOR THE COVERING ABSTRACT, SEE IRRD ABSTRACT NO 107035.
