IMPROVEMENT TO AND DISSEMINATION OF PAVEMENT DESIGN AND MAINTENANCE TECHNIQUES

AMELIORATION ET DIFFUSION DES METHODES ET TECHNIQUES DE DIMENSIONNEMENT ET D'ENTRETIEN DES CHAUSSEES

TO COORDINATE THE DISSEMINATION AND PREPARATION OF TECHNICAL DOCUMENTS: INSTRUCTIONS FOR SECONDARY ROADS AND LIGHTLY-TRAFFICKED ROADS; IN-DEPTH STUDY OF THE MECHANISM OF PAVEMENT FAILURE; USE OF NEW MATERIALS; USE AND INTERPRETATION OF RESULTS OF CIRCULAR TRACK FATIGUE TESTS ON PAVEMENTS IN NANTES. IN 1978, GUIDELINES FOR THE STRENGTHENING OF PAVEMENTS AND FOR ROAD MAINTENANCE WERE DRAFTED IN COLLABORATION WITH THE SETRA. IN 1979, THE MAIN STUDY THEMES WILL BE THE DEVELOPMENT OF NEW MATHEMATICAL MODELS FOR THE MAINTENANCE AND OPERATION OF THE FATIGUE CIRCULAR TRACK AND DEFINITION OF NEW NONDESTRUCTIVE TESTING METHODS.
