Laying method of the type in which: on the roadbed (1) a binding liquid or pasty layer (2) is laid, substantially made up of binding resin that sticks to the surface of the road carpet and subsequently hardens; on said liquid or pasty layer (2), before the hardening, an aggregate material layer in granules (3) is evenly laid, in such a way that once the hardening of said resin (2) has occurred, said aggregate material in granules (3) is strongly bound to the road carpet; the aggregate material in granules that has not been adequately fixed to the roadbed is removed; where: said aggregate material in granules is artificially produced; its granules are polygon-shaped with sharp corners; the constitutent material is a mixture of forsterite, spinel, magnesium chromate and iron in which the presence of A1203 for a value comprised between 5 % and 15 % preferably about 10/11 % is provided. In this way an optimal coating is obtained. |
