Abstract
The article presents the results of modeling temperature fields in multi-layer road pavement based on monitoring results on an operating road. The relevance of the work is due to the high influence of temperature on the elastic moduli of asphalt concrete, and, as a consequence, on the results of tests to assess the strength of road pavements performed under different temperature conditions. The research included an analysis of data accumulated over a long period of time from a temperature monitoring station installed during the construction of the highway. A technique is proposed based on solving the problem of thermal conductivity for each cohesive layer of road pavement, taking into account the continuity of temperature and heat flux density when passing through interlayer boundaries, which makes it possible to determine the temperature field in the first layer at an unknown temperature on the surface and clarify the mechanical and thermophysical parameters of the rest layers. An analysis was carried out of the degree of heterogeneity of temperature distribution across layers in different periods of the year, allowing for strength tests. Directions for further research are outlined to update the obtained methods, taking into account the use of modern types of asphalt concrete in road pavement structures.
