STUDY OF THE MODIFICATION IN THE CHARACTERISTICS OF STONE AGGREGATES THROUGH THERMAL ACTION IN DRYERS IN ASPHALT MIXING PLANTS

ESTUDIO DE LA MODIFICACION DE LAS PROPIEDADES DE LOS AGREGADOS PETREOS POR EL EFECTO TERMICO EN LOS SECADORES DE LAS PLANTAS ASFALTICAS

A study is presented of the modifications in the characteristics of aggregates, measured through changes in wear, adhesion and mineralogical composition when they are subjected to the high temperatures of mixing plant dryers. An attempt is also made to develop a simple laboratory method of reproducing these changes with a view to obtaining a better evaluation of the practical behaviour of these materials. The results obtained show that thermal modifications can be of importance or not depending on the type of materials used. (TRRL)
