STUDY OF RESIN MORTARS FOR SURFACE DRESSINGS

ETUDE DE MORTIERS DE RESINE POUR REVETEMENTS SUPERFICIELS ROUTIERS

The author recalls that the increase in traffic led to research into new materials to improve the roughness and increase the lifetime of surface dressings. A first series of tests on pure epoxy polymer resulted in the selection of some resin-hardener systems which better fulfill physico-chemical criteria (viscosity, adhesion and reactivity), mechanical strength and thermal stability between - 10 degrees C and + 50 degrees C. These epoxy polymers are rigid at 20 degrees C (e = approximately 25000 bars). The techniques adopted in the laboratory to control the properties of synthetic mortars is a follows: tensile test at 20 degrees C on a dumb-bell-shaped sample; dynamic crushing test; dry and wet micro deval test. Some additional measurements were conducted: measurement of porosity, scanning electron microscopic study of mortar structure and some tensile tests at - 10 degrees C and + 50 degrees. C. /TRRL/
