STRENGTHENING OF BITUMINOUS PAVEMENTS

RENFORCEMENT DES CHAUSSEES A REVETEMENTS HYDROCARBONES

A PROCEDURE FOR CALCULATING THE THICKNESSES OF STRENGTHENING LAYERS IS TO BE ESTABLISHED BASED ON THE RRC METHODS FOR DIMENSIONING BITUMINOUS PAVEMENTS AND TAKING ACCOUNT OF RESULTS CONCERNING THE MECHANICAL PROPERTIES OF THE MATERIALS AND THEIR SEASONAL VARIATIONS. THE PROCEDURE WILL ALSO BE BASED ON AN EVALUATION OF THE BEARING CAPACITY OF THE EXISTING PAVEMENT, ON CALCULATED STRESSES AND DEFORMATIONS, ON DIMENSIONING CRITERIA AND ON THE RESULTS OF EXPERIMENTAL VERIFICATION (LACROIX DEFLECTOGRAPH MEASUREMENTS AND STRUCTURAL ANALYSIS). A STANDARD STRUCTURES HANDBOOK FOR STRENGTHENED BITUMINOUS ROADS WILL BE ISSUED AS A RESULT OF THIS WORK.
