AGGREGATE TESTS

ESSAIS DE GRANULATS

THE NEW VOLUME OF RECOMMENDATIONS FOR AGGREGATES LISTS THE TESTS TO BE CARRIED OUT TO MEASURE THEIR CHARACTERISTICS. AS REGARDS THE TESTS ON O/D AND D/D AGGREGATES, 10 TEST PROCEDURES OUT OF THE 19 NECESSARY EXIST. THE REMAINING 9 WERE THE OBJECT OF STUDIES, AND IT IS HOPED THAT ALL WILL BE DRAWN UP IN TWO YEARS TIME. IN 1976, THE WORK WILL BE CONCENTRATED ON THE REMAINING 9 TEST PROCEDURES, E.G.: ORGANIC MATTER CONTENT, SOLUBLE SALT CONTENT, IDENTIFICATION, SAMPLING ON THE SITE, COEFFICIENT OF ELONGATION, ANGULARITY, SURFACE CLEANLINESS, WEATHERABILITY, HOMOGENEITY.
