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.
L'invention concerne un procédé de répandage qui consiste à répandre sur l'assiette de route (1) une couche liquide ou pâteuse de fixation (2) sensiblement constituée de résine de liaison qui adhère à la surface du revêtement puis durcit; à répandre uniformément sur ladite couche liquide ou pâteuse (2), avant le durcissement, une couche de matériau granulé (3), de manière qu'après le durcissement de la résine (2), le matériau granulé (3) adhère fermement à la surface du revêtement; et à enlever le matériau granulé qui ne s'est pas fixé de façon apporpriée à l'assiette de route. Le matériau granulé est produit artificiellement. Les granules du matériau granulé ont une forme de polygone à angles aigus. Le matériau constituant est un mélange de forstérite, de spinelle, de chromate de magnésium, et de fer, avec une présence de A1203 se situant entre 5 % et 15 %, de préférence 10/11 %.
