THE OCCURRENCE, CAUSES AND PREVENTION OF PERMANENT DEFORMATIONS IN BITUMINOUS ROAD PAVEMENTS
| 项目名称： | THE OCCURRENCE, CAUSES AND PREVENTION OF PERMANENT DEFORMATIONS IN BITUMINOUS ROAD PAVEMENTS |
| 摘要： | THE OBJECT OF THE STUDIES IS TO ESTABLISH PERMANENT DEFORMATIONS ON ROADS, TOGETHER WITH THE MATERIAL PROPERTIES OF VARIOUS LAYERS OF THE ROAD STRUCTURE, AND WORK OUT RECOMMENDATIONS FOR DECREASING THESE DEFORMATIONS. RESISTANCE TO PERMANENT DEFORMATION IS TO BE DEFINED AND WORKED OUT AS A STRENGTH CRITERION. WORK IS BEING COORDINATED WITH RESEARCH CARRIED OUT AT THE UNIVERSITY OF NOTTINGHAM, GREAT BRITAIN, TRRL, THE CENTRE DE RECHERCHES ROUTIERES, BELGIUM, THE ESSO FRANCE RESEARCH CENTRE, THE ROYAL DUTCH SHELL LABORATORY, THE SWISS FEDERAL INSTITUTE OF TECHNOLOGY AND THE UNIVERSITY OF KARLSRUHE. THE PLAN OF WORK IS: SELECTION OF SUITABLE SECTIONS OF ROADS UNDER TRAFFIC HAVING DIFFERENT RUT DEPTHS FOR CORE SAMPLING; MEASUREMENT OF DEFORMATIONS IN THE ROADBASES TO CALCULATE THE LOCATION OF THE GREATEST STRESSES IN MULTILAYERED SYSTEMS BY MEANS OF BISAR; CARRYING OUT OF STATIC AND DYNAMIC TRIAXIAL TESTS AND OF TENSILE COMPRESSION TESTS ON CORE SAMPLES; DEFINING A LINK BETWEEN TRAFFIC LOADING AND PERMANENT DEFORMATIONS ON ROADS. |
