Temperature gradient of RCC-AC composite pavements
In this paper, the temperature gradient of a composite pavement structure - asphalt pavement on top of roller compacted portland cement concrete pavement (RCC-AC) is studied based on the thermo-conductivity theory. The temperature yearly variation is approximately expressed with the temperature variation coefficient and the yearly average maximum and minimum temperature of the ground (pavement surface). The temperature daily variation is described with the daily maximum/minimum temperature effect coefficient. Based upon the boundary conditions of the composite pavement structure, the analytical solution of the temperature gradient of the composite pavement is given, and the method of weighted residuals (MWR) on solid mechanics and the principles of heat transfer are used in the study. The effect of both yearly and daily temperature variance on the temperature gradient of composite pavement is investigated. Copyright ASCE 2008.
