GRANULAR MATERIAL BASED ON RUBBERLIKE MATERIALS AND METHOD FOR MAKING SAME

摘要

The invention concerns a granular material based on synthetic substances or the like used in a road surfacing composition or the like. The invention is characterised in that each granule (1) of material consists in at least a granule and/or at least a particle of rubber (2, 2') closely bonded with thermal bonding (3) and/or fibre strands (4). The invention also concerns a method for making said granular material, characterised in that it comprises steps which consist in: transforming rubber and heat binding glue into granules, and/or particles and then closely mixing the rubber granules and the heat binding glue, then heating the mixture at a temperature ranging between 80 DEG C and 300 DEG C so that the heat binding glue granules are liquefied and coat the granules and/or particles of rubber, and finally cooling said granules.
