MIXED STRUCTURES

项目名称：	MIXED STRUCTURES
摘要：	THE FIRST PHASE OF THE STUDY WILL INVESTIGATE THE SPECIFIC ASPECTS OF THIS TYPE OF PAVEMENT (MECHANICAL ASPECT; DETERIORATION; NON DESTRUCTIVE TESTING) AND TO SINGLE OUT SENSITIVE AREAS AND LIMITS OF THIS TYPE OF PAVEMENT. IT IS THEREFORE NECESSARY TO CONTINUE THE INVESTIGATIONS STARTED IN 1978. IN 1979 THE FOLLOWING WORK WILL BE UNDERTAKEN: (1) TO INCREASE THE NUMBER OF MEASUREMENTS OF THE DEFORMATION OF THE CORE SAMPLE TO DEFINE CONDITIONS OF ADHESION AND STRIPPING BETWEEN BITUMINOUS AND CEMENT ROADBASES; (2) TO BETTER DEFINE THE ROLE OF TEMPERATURE IN THE BEHAVIOUR OF BITUMINOUS ROADBASES AND ROADBASES STABILIZED WITH HYDRAULIC BINDERS; (3) TO INSTALL FIXED MEASURING GAUGES FOR INVESTIGATING ANOMALIES IN INTERMEDIARY BITUMINOUS LAYERS, OBSERVED WITH CAVITY MEASUREMENTS; (4) TO EXAMINE OTHER CASES OF SIMILAR TYPICAL DETERIORATION WITH A VIEW TO IDENTIFYING THEM IN NON-DESTRUCTIVE TESTING.
