RECOMMENDATIONS FOR APPOINTMEN OF ASPHALT FOR ROAD SURFACES

Abstract

In Russia, typical designs of road clothes for federal highways are being developed. Typical designs will avoid design errors and ensure their effective operation within the regulatory lifetime. Development of standard designs of road clothes is carried out taking into account well-grounded recommendations on the design characteristics of the clothes of coatings and substrates: the type of material, the thickness of the layer, the number of layers, the combination of materials in the structure. The recommendations for the design of road clothes for federal highways can be extended to any public highway. This article presents the results of the performed analysis of the practice of applying various types of asphalt road surfaces on federal highways of Russia with flexible pavements. The recommendations on the appointment of the type of asphalt road surface have been developed depending on the conditions of operation of the highway for the application of these rules in the design of flexible pavements.
