IN DEFENCE OF AGGREGATES /IN FRENCH/

THE IMPORTANCE IS EMPHASIZED OF AGGREGATE QUALITY IN ROAD CONSTRUCTION. THE COST OF IMPROVING AGGREGATES WOULD AFFECT ONLY VERY SLIGHTLY THE COST OF THE COMPLETED WORK AND WOULD INCREASE THE DURABILITY OF THE ROAD. THE FOLLOWING IMPROVEMENTS ARE RECOMMENDED: (1) HOMOGENEITY, RATIONALIZATION AND STANDARDIZATION OF AGGREGATE PRODUCTION TOGETHER WITH THOROUGH GRADING, (2) POSSIBILITY OF SELECTING CRUSHED SAND WITH HIGH CONTROLLED FINES CONTENT OR WASHED SAND WITH FILLER ADDED WHEN NECESSARY. (3) CONTROL AND CORRECTION OF MOISTURE CONTENT, ESPECIALLY IN SAND. PRELIMINARY TREATMENT WITH WATER-REPELLANT PRODUCTS AND PROTECTION OF SAND DURING STORAGE WITH PLASTIC FILMS ARE RECOMMENDED, AND (4) SYSTEMATIC SUPPLY OF AGGREGATES, ADEQUATELY LAID OUT STORAGE SPACE, AND EFFICIENT QUALITY CONTROL. /LCPC/RRL/
