The method of assessing the condition of roads

Abstract. To determine the need for repair measures, types of repair measures and their priority on the highway network, it is necessary to assess their current condition. Various studies have proposed enlarged criteria for assessing the condition of the highway, mainly based on longitudinal flatness and the presence of pavement damage: PCI coating condition index, SCI surface condition index, OPCI general index of the condition of urban streets and roads, PSCI surface condition index, etc. In the Russian Federation, the condition of highways is assessed by determining the values of longitudinal evenness, coefficient of adhesion, coating condition and modulus of elasticity. At the same time, determining the modulus of elasticity for highways of regional and local significance within the framework of annual diagnostics in conditions of limited funding is ineffective and impractical. The authors introduced a comprehensive indicator of the level of maintenance, based on the values of the coefficient of adhesion, longitudinal evenness and the condition of the coating. The use of this indicator will improve the efficiency of planning repair activities on the highway network. A method for assessing the condition of highways consisting of two stages is proposed. At the first stage, the level of operational maintenance is determined and local areas with significant deformations and failures are identified. At the second stage, the causes of the development of significant deformations and destructions are determined by conducting geological, hydrometric and geodetic studies. This approach will allow in conditions of limited funding. reduce the cost of annual road diagnostics without reducing its effectiveness.
