Temperature Condition of Asphalt Concrete During Road Usage

The article is devoted to the behavior of asphalt concrete with a change in air temperature. The subject of the study is the temperature regime of asphalt concrete. The aim of this work is to assess the effect of changes in air temperature on the strength characteristics of asphalt concrete and develop proposals to reduce the negative impact on asphalt concrete. This will prevent the occurrence of destructive processes in the pavement coating, supporting the transport and operational performance of roads. And as a result, it will lead to an increase in the service life of roads, which is an urgent task. As a result of the work carried out in laboratory conditions, the dependences of low-temperature voltage are obtained. Based on the calculation, a curve of the annual distribution of the coating temperature is obtained, and the values of extreme temperatures for the city of St. Petersburg are found. Suggestions have been developed to reduce the effect of ambient temperature on the surface of the road surface.
