WEARING COURSES (PAVEMENT DESIGN)

LES COUCHES DE ROULEMENT (DIMENSIONNEMENT)

THE AIM OF THE RESEARCH IS TO OBTAIN BETTER KNOWLEDGE OF THE ROLE AND OPERATION OF WEARING COURSES WITH A VIEW TO CONDUCTING A COHERENT STUDY OF THE DESIGN OF THESE LAYERS. IN 1979, AN ATTEMPT WILL BE MADE: (1) TO CARRY OUT A THEORETICAL STUDY OF PAVEMENT DESIGN BY MEANS OF CALCULATIONS (LCPC); (2) TO MAKE A BIBLIOGRAPHIC SEARCH IN FRANCE AND IN OTHER COUNTRIES (REGIONAL LABORATORY LILLE); (3) TO REVIEW THE NUMBER AND BEHAVIOUR OF WEARING COURSES IN STRENGTHENED AND NEW PAVEMENTS OVER THE WHOLE OF THE COUNTRY (REGIONAL LABORATORIES LILLE, BLOIS, ST BRIEUC, TOULOUSE, LYON); (4) TO MAKE OBSERVATIONS ON EXPERIMENTAL SECTIONS WHERE DIFFERENT TYPES OF SURFACINGS HAVE BEEN LAID (REGIONAL LABORATORIES LILLE, TOULOUSE). EACH STUDY WILL BE LINKED TO OTHER INVESTIGATIONS ALREADY STARTED.
