The Use of Cold Recycling Technology to Increase the Resistance of Pavements to Rutting

Abstract

Abstract The purpose of the article is to develop the construction of pavement with increased resistance to rutting, arranged during the repair of existing asphalt concrete pavements by cold recycling. It was established that the location of the ruts on the roadway is due to the distribution of the driveways of wheels of transport along the width of the lanes. Constructions of pavement with unequal strength along the width of the lane are proposed. Such constructions are arranged during the repair of pavement by milling asphalt concrete at the locations of the ruts by their width (90-100) cm and mixing the asphalt granulate with cement using cold recycling technology. The resulting mixture is placed in pits obtained by milling ruts, and compacted. As a result, two parallel strips of new monolithic material are obtained on the surface of the repaired coating within each lane. A new leveling or structural layer of asphalt mix is arranged on the existing coating with repaired ruts. During the exploitation of such pavement, hidden elements are hidden from the driver. Therefore, the nature of the distribution of passages along the width of the carriageway remains the same, but sections of the base located under the places of formation the rut under the new coating are made of durable, slightly deformable material.
