Abstract:
For the lack of quantitative analysis and reasonable evaluation methods on skid-resistant performance of cement concrete pavement, this paper adopts the finite element method to simulate the frictional contact condition between tire and cement concrete pavement and then analyzes the impact of load, pavement surface structure, tire pressure, speed and other factors on adhesional coefficient between tire and pavement. The results indicate that: the load, groove width and groove space significantly affect adhesional coefficient, but groove depth has hardly effect on adhesional coefficient; the lower the inflation pressure of tire, the greater the adhesional coefficient between tire and pavement is; the faster the speed, the smaller the adhesional coefficient is. At last, the relationship among pavement adhesional coefficient and inflation pressure, load, speed, and surface structure parameters is acquired. 5 tabs, 7 figs, 10 refs.
