| Abstract: | The back calculation of pavement layer moduli and the method of estimate is researched according to the measured FWD data from the field test of the existing cement concrete pavement road.The practicability of estimate of existing cement concrete pavement based on deflection basin is analyzed.The back calculating ability of common network and noise network is compared through the back calculation of theoretical regress and neural networks method.The key techniques are presented for the back calculation of moduli with artificial neural networks. |
