CONSTRUCTION METHODS AND EQUIPMENT

METHODES ET MATERIEL D'EXECUTION

THE AIM OF THE RESEARCH IS TO IMPROVE THE QUALITY OF APPLICATION BY DEFINING CRITERIA FOR THE SELECTION AND OPERATION OF CONSTRUCTION MACHINERY. IN 1976, IT IS ENVISAGED TO STUDY: (1) THE RELATIVE IMPORTANCE OF THE DIFFERENT PARAMETERS OF VIBRATING COMPACTORS WITH THE EXPERIMENTAL VIBREX COMPACTOR (SUSPENDED MASS/LOW VIBRATING MASS RATIO, INFLUENCE OF SUSPENSION CHARACTERISTICS), (2) INFLUENCE OF THE LOAD PER WHEEL AND TYRE PRESSURE FOR PNEUMATIC-TYRED ROLLERS, (3) MAIN SPREADING PROBLEMS (THICKNESS AND EVENNESS OF THE LAYER) ACCORDING TO DIFFERENT TYPES OF MACHINES (GRADERS, FINISHERS) AND GUIDING TECHNIQUES.
