Abstract

This paper presents instrumental assessment of the pavement condition of the section (length: 43 km) of “Ekaterinburg-Almaty” highway located in the Kostanay region (northern Kazakhstan). The pavement condition indicators (roughness, rut depth, total length of longitudinal and transverse cracks, areas of asphalt concrete pavement with block cracks, pavement surface modulus) were evaluated using a mobile diagnostic laboratory (Dynatest, Denmark). It has been established that: due to high moisture in the upper part of the subgrade during the spring thawing period, significant accumulation of plastic strains is possible; longitudinal and transverse cracks are the main type of destruction of the asphalt concrete pavement.
