Non-stationary temperature regime of the pavements

摘要

The results of the complex (experimental and theoretical) research of the temperature regimeof the flexible pavement and its subgrade in the non-stationary carrying-out in January (the coldest month ofthe year) and August (one of the hottest month of the year) in the climatic conditions of the Northern-EasternKazakhstan. The subgrade is represented by sandy clay. The experimental temperature measurement in the pointsof the pavement have been realized by thermo-electrical indicator of the resistance. The theoretical research ofthe non-stationary regime of the pavement and subgrade has been realized under the program ROTER designedby the author on the basis of the finite element method which takes into consideration phase transfer of thedampness in the subgrade. The comparison of the theoretical and experimental results showed their satisfactorycoincidence.
