STUDY OF THE COMPACTION OF BITUMINOUS MIXTURES

ETUDE DE LA COMPACTION DES ENROBES BITUMINEUX

A GYRATORY COMPACTION PRESS WAS USED TO INVESTIGATE THE PARAMETERS WHICH INFLUENCE THE VOLUMETRIC DISTRIBUTION OF THE VARIOUS INGREDIENTS OF A BITUMINOUS MIXTURE (BINDER, AGGREGATES, AIR). MOST OF THE SAMPLES PREPARED WERE CRUSHED AT 60 DEG C ACCORDING TO THE MARSHALL PROCEDURE, SO AS TO STUDY THE INFLUENCE OF COMPACTION ON THE MECHANICAL CHARACTERISTICS. THE INFLUENCE OF THE FOLLOWING ASPECTS OF MIX DESIGN WAS SYSTEMATICALLY STUDIED: BITUMEN CONTENT, PROPORTION OF FILLER, SHAPE OF THE GRADING CURVE, SIZE OF CHIPPINGS, ANGULARITY OF SAND, TOGETHER WITH COMPACTION INTENSITY. THE RESULTS SHOWED THAT THE APTITUDE TO COMPACTION OF BITUMINOUS MIXTURES IS A FACTOR WHICH MUST BE TAKEN INTO ACCOUNT IN MIX DESIGN.
