CONTROL OF PAVEMENT CONSTRUCTION BY MEANS OF THE LA CROIX-LPC DEFLECTOGRAPH (IN FRENCH)

THE LA CROIX - PPC DEFLECTOGRAPH IS MAINLY USED FOR STUDYING THE STREGTHENING OF EXISTING PAVEMENTS. THIS ARTICLE RELATES ITS UTILIZATION FOR CONTROLLING THE CONSTRUCTION OF TWO MOTORWAY STRETCHES: A RIGID SECTION AND A FLEXIBLE SECTION WITH GRANULATED SLAG-TREATED LAYERS. IN THE CASE OF THE FLEXIBLE PAVEMENT IT ENABLED A SMALL BADLY DRAINED ZONE TO BE LOCATED AND SUBSEQUENTLY TREATED; IN THE CASE OF THE RIGID PAVEMENT, DIFFICULT WEATHER CONDITIONS (RAIN AND LOW TEMPERATURE IN LATE AUTUMN) INTERFERED WITH THE MEASUREMENTS CARRIED OUT ON PAVEMENT LAYERS; HOWEVER, IT WAS POSSIBLE TO OSBERVE A SYSTEMATIC DEFECT IN COMPACTION IN THE VICINITY OF ENGINEERING STRUCTURES, AND TO FOLLOW THE EVOLUTION IN THE SETTING OF GRANULATED SLAG-TREATED LAYERS. THESE RESULTS SHOW THE POSSIBLE USES OF THE DEFLECTOGRAPH FOR THE SURVEILLANCE AND OVERALL CONTROL OF PAVEMENT CONSTRUCTION, OR CONTROL OF EACH LAYER, ASSUMING THAT THE PAVEMENT COURSES ARE SUFFICIENTLY STABLE. /A/LCPC/RRL/
