- Abstract
This research lies within the framework of identifying and validating practical and cost-effective solutions that would contribute to reusing millions of tons of granular materials from abrasives spread every year in Québec to ensure transportation safety in winter. The behavior of abrasives shows degradation of their inherent properties, essentially due to a transformation of their grading range that shrinks, resulting mainly from compressive stresses between the passing of traffic and the pavement. Nonetheless, they keep their mechanical properties classifying them in category 1 fines in the NQ 2560-11/2002 standard of the 'Bureau de normalisation du Québec' in 2002. The results of physical characterization tests show a number of re-use possibilities in line with current laws, standards and regulations in Québec. An application in asphalt mixes is successfully tested.
