Abstract:
In order to increase the accuracy of the temperature field computational simulation of asphalt pavement, this paper puts forth a new method named meshless method for computing pavement transient temperature field based on variational principle. The essential boundary conditions are dealt with penalty function method. This method is applied to a practical case, the numerical model is developed for simulating analysis. The results show that the biggest error of meshless method compared to the the measured data is less than 2.6%, and it is less than 3.5% of the finte element method. 1 tab, 2 figs, 13 refs.
