<p>The invention concerns a reinforcing fibre material for bituminous aggregates for road surfacing produced from glass filaments, advantageously consisting of bits of glass fibres or clipped fibres, with a mean diameter more than five micrometers and a length more than six millimetres. The method comprises a selection step, optionally a step which consists in mixing the selected fibres, and a grinding step which consists in cutting up the mixed fibres into filaments with length not less than six millimetres. Advantageously, the fibre material is in the form of flakes.</p> |
