Summary: | The purpose of the article is to determine the contribution of wear of asphalt concrete pavement to the depths of ruts. The method of experimental research is field and laboratory tests. In the course of field work, the thickness of the asphalt concrete pavement in the core taken from the bottom of the rut, between the rut and side bulging of rut, if any, is measured. When performing laboratory work, the indicators of the physical and mechanical properties of asphalt concrete are determined in samples taken from the coating and in reformed samples. Laboratory data make it possible to judge the compliance of asphalt concrete with the requirements of the standard and evaluate its possible compaction by transport during exploitation. The difference in the thickness of the asphalt concrete in the cores taken from different points of the cross-section of the coating allows us to determine the amount of wear and calculate its share in the depth of the rut. As a result, share of the rut depth caused by the wear of the asphalt concrete pavement and the deformation of the structural layers of the pavement and the soil of subgrade were established. |
