For quartzite, tillite, shale and G1 to G4 materials, measure the soluble salts against pH or electrical conductivity. Use the material if the pH is >10 after treatment at the crushing plant, and subsequently remains = 8,0. If the pH is <6,0 treat with lime until the pH = 10,0 before use. For natural gravel and other crushed aggregate, use the

For use in the wearing course layers of roads, tight abrasion resistance restrictions are in place to prevent excessive degradation under traffic load. According to the Spanish standards for road construction ( Ministerial Order PG-3/75, 1976 ), LA coefficients less than 35% are required for crushed aggregate under low traffic conditions and less than 40%

HMA Pavement. HMA pavements are classified as “flexible” pavements because the total pavement structure deflects, or flexes, under loading. A flexible pavement structure is typically composed of several layers of material. Each layer receives the loads from the above layer, spreads them out, then passes on these loads to the next layer below.

The base layer forms the foundation for the road surface. The bottom layer essentially comprises an unbound mixture of coarse and fine crushed stone, as well as crushed sand, to achieve the desired load-bearing capacity and absorb traffic loads so that the underlying subgrade is not deformed.

There are several layers of each material compacted into the overall pavement to ensure the final road surface can handle heavy duty traffic and weathering. The pavement and subgrades are designed to distribute the weight and impact of traffic evenly through the layers, so that not just one layer is taking the punishment of that load.
