EQUIPMENT FOR THE MECHANICAL TREATMENT OF QUARRY MATERIALS FOR THE PRODUCTION OF ROAD CONSTRUCTION AGGREGATES. (1) JUSTIFICATION OF THE DEFINITIONS AND STRICT SPECIFICATIONS DRAWN UP BY THE ADMINISTRATIVE AUTHORITIES

LES EQUIPEMENTS DE TRAITEMENT MECANIQUE DES MATERIAUX EN CARRIERE POUR LA PRODUCTION DES GRANULATS ROUTIERS - 1) JUSTIFICATION DES DEFINITIONS ET SPECIFICATIONS RIGOUREUSES ETABLIES PAR L'ADMINISTRATION

THIS ARTICLE PUTS FORWARD ARGUMENTS IN FAVOUR OF THE STRICT SPECIFICATIONS IMPOSED BY THE ADMINISTRATIVE AUTHORITIES, TAKING INTO ACCOUNT THE FACT THAT LABORATORY TESTS DO NOT SIMULATE SATISFACTORILY THE CONDITIONS OF THE EVOLUTION OF AGGREGATES IN PAVEMENT LAYERS. IT IS HOPED THAT SOON SIMULATION CONDITIONS WILL BE IMPROVED. MENTION IS MADE OF THE 13 T LOAD/AXLE/PAVEMENT DETERIORATION RELATIONS. A STUDY IS PERFORMED OF QUALITY SHAPE, HARDNESS AND CLEANLINESS. WARNING IS GIVEN OF THE SERIOUS RISKS OF NOT FULFILLING THE STRICT SPECIFICATIONS ESTABLISHED.
