Determination of macrotexture
CHARACTERISTICS
The sand is natural, siliceous. It is clean, the grains are generally isometric and rounded in shape. It is dried, screened and prepared in a modern workshop offering all guarantees of quality and regularity.
The sand is packaged in polyethylene bags each containing 1000. ± 10 g.
Deliveries are made in boxes of 20 bags weighing 20.5 kg, and in pallets of 36 to 45 boxes with a gross mass of 753 to 935 kg, protected by a polyethylene cover (road transport) or reinforced cardboard (sea transport) .
CONTROLS
The particle size composition, determined by sieving, complies with the requirements of standard NF P98-216-1 (§ 6).
Tamis ouverture des mailles (mm) | Passant cumules (%) |
0.16 | ˂4 |
0.315 | ˃98 |
These analyzes are supplemented by controls of the humidity level.
APPLICATION AREAS
This sand is used to carry out the so-called HSv test: “measurement of the true sand depth”, which consists in characterizing the roughness of a road surface. It provides an average thickness of the hollow asperities of the road layer. It varies from 0.3mm for smooth roads to over 2mm for very rough roads.
