Abstract
The article discusses the use of waste metallurgical plant, waste foundry sand (OFS) in comparison with other small aggregates in the composition of asphalt concrete mixture. Due to the constantly growing intensity and loads from the rolling stock, there are high demands on asphalt concrete pavements. Basically, the stability of asphalt to shear deformations depends on the strength characteristics. Thus, the higher the strength of the asphalt concrete when testing samples at high temperature, the higher the shear stability of the road surface. One way to reduce the cost of building a highway, possibly through the use of industrial waste in the structural layers of pavement. The article presents the results of asphalt concrete tests using natural sand, quartz sand and waste foundry sand.
