TO DRAFT METHODS OF NONDESTRUCTIVE TESTING FOR FLEXIBLE PAVEMENTS USING EXISTING MEASUREMENT SYSTEMS. THE DEVELOPMENT OF THIS METHODOLOGY NECESSITATED A LARGE NUMBER OF MEASUREMENTS ON 25 TEST SECTIONS, ESPECIALLY MEASUREMENTS OF THE DEFORMATION OF CORE SAMPLES. THE SCANNING OF THESE MEASUREMENTS, PART OF WHICH IS STILL TO BE CARRIED OUT, LED TO THE DEVELOPMENT OF THE MAIN PARTS OF THIS METHOD OF ANALYZING THICK BITUMINOUS PAVEMENTS. IN 1979 THE PROGRAMME WILL CONSIST IN MAKING GENERAL USE OF THE TESTS CONDUCTED AND IN DRAFTING NONDESTRUCTIVE TESTING METHODS.
