CALCULATION OF THE SURFACE TEMPERATURE OF THE ROADWAY
The purpose of the work was to study the influence of temperature conditions of road operation conditions and thermophysical properties of the soils of the road base on the change in the dimensionless temperature of the roadway surface. The operating conditions of roads in the winter and summer period of the year are considered. Calculated dependencies for determining the dimensionless and dimensional temperature of the road surface are given. A comprehensive qualitative and quantitative analysis of the influence of temperature conditions of road operating conditions and thermophysical properties of road base soils on changes in the dimensionless temperature of the roadway surface is carried out. The main qualitative and quantitative characteristics of the influence of the temperature factor, the coefficient of heat absorption of the soil and the wind speed on the dimensionless temperature of the road surface have been established. In particular, it is shown that the coefficient of thermal assimilation of the soil of the road base has a stronger effect on the temperature of the road surface in winter. At the same time, the dependence of the dimensionless temperature on the heat absorption coefficient decreases over time, both for the summer and winter periods at approximately the same pace. The results of numerical calculations are presented in the form of 2D and 3D graphs, which make it possible to visually assess the influence of the initial climatic and thermophysical parameters on the range of changes in the dimensionless temperature of the roadway surface in the summer and winter periods of the year.
