AbstractAbout AuthorsReferences
In many, practically significant cases, the thermal factor determines the reliability and safety of the operation of roads in permafrost, especially in a sharply continental climate, when daily changes in air temperature and road surface can reach tens of degrees. To reduce the negative impact of sudden changes in daily temperatures on the load-bearing capacity of roads, you can use structural layers of materials with a high value of thermal massiveness in road clothing. Quantitative regularities of changes in the optimal concentration of heat-intensive filler in the structural layer to achieve the maximum index of thermal massiveness of road surfaces are obtained. 2D and 3D graphs are presented that allow us to estimate the possible range of changes in the optimal concentration of heat-intensive filler in the structural heat-protective layer of the road surface both in a wide and characteristic range of changes in the initial values.
