CONTRIBUTION TO THE UPDATING OF THE DIRECTIVES FOR ROADBASES STABILIZED WITH HYDRAULIC BINDERS |
摘要: |
THE DIFFERENT DIRECTIVES FOR THE CONSTRUCTION OF GRAVEL ROADBASES STABILIZED WITH HYDRAULIC BINDERS WERE ESTABLISHED USING DATA (STUDIES, INVESTIGATIONS AND OBSERVATIONS) OF AT LEAST 5 YEARS OF AGE. THE OBJECTIVE OF THE RESEARCH IS TO FIND FRESH DATA NECESSARY TO THE UPDATING OF THESE DIRECTIVES. THE THREE MAIN IMMEDIATE OBJECTIVES ARE: TO DEFINE THE PERFORMANCE LEVELS TO BE ATTAINED FOR EACH CATEGORY OF STABILIZED ROADBASE; TO STANDARDIZE AND OPTIMIZE STANDARDS GOVERNING AGGREGATES; TO DETERMINE THE DISPERSION THRESHOLDS NOT TO EXCEED DURING ROAD CONSTRUCTION. IN 1979 IT IS PLANNED: TO STUDY VARIATIONS IN THE MECHANICAL CHARACTERISTICS OF GRAVEL-CEMENT AS A FUNCTION OF FLUCTUATION IN CEMENT PROPORTIONING, MOISTURE CONTENT AND DENSITY; TO STUDY THE MECHANICAL CHARACTERISTICS OF GRAVEL SLAG WITH A FULL CURVE, WITH VARYING FINES CONTENTS. A SUMMARY WILL BE PREPARED OF OBSERVATIONS ON CONTROLS IN FIXED PLANTS MANUFACTURING GRAVEL AND SAND-SLAG IN THE PARIS REGION. |
