ASSESSMENT OF THE ROAD PAVEMENT CONDITION ON THE SECTION OF THE HIGHWAY N-25.

Abstract

Based on the field and laboratory studies carried out on the road section km 176+536, the technical parameters of the existing pavement were determined and its permissible elastic deflection was calculated. Recommendations were developed for the arrangement of reinforcing layers of the existing pavement by partial or complete replacement of the lower asphalt concrete layer.

In case of partial replacement of the existing asphalt concrete, it is recommended to arrange an additional structural base layer with a complex binder. In the case of using crushed existing asphalt concrete (granulate), it is recommended to add C7 or C8 road mixtures mixed in mobile or stationary plants with a complex binder.
