MODERN TECHNOLOGIES OF UPPER CEMENT-CONCRETE LAYERS RUT REPAIRS ON THE EXAMPLE OF A SECTION OF THE M-4 "DON" AUTOMOBILE ROAD

Abstract

This article is devoted to the condition analysis and modern methods development for restoring cement concrete pavement evenness of the M-4 "Don" highway using example of section «Moscow Ring Road – Kashira» (km 52 - km 71). With mobile road laboratory rut formation dynamics on a cement concrete pavement was assessed. The possible causes of this defect were studied. Based on data obtained, a number of effective and economical methods was proposed for cement concrete pavement restoration. A detailed technology description using modern mechanisms and materials is given. Timely implementation of road repairs to eliminate rutting will extend the service life of cement concrete pavements up to 30 years and reduce the need for more expensive work in case of deep pavement damage. The repair methods considered in the article were recommended by the Avtodor State Corporation for practical application.
