Abstract:
To analyse the application of handy friction tester in the evaluation of pavement skid-resistant performance, this paper firstly studied the components and work theory of this tester. This device can test the friction of field pavement surfaces, then the correlation between this device and the other equipments is established after a large number of experiments. The results indicate that: the astroturf drag and exposed-aggregate cement concrete pavement have a good relationship among British pendulum number, texture depth and handy friction factor, but not with groove; for the different types of surface texture, it has the good correlation among the handy friction factor, profile frictional coefficient and sideway force coefficient; this tester and SCRIM vehicle evaluation of the skid-resistant levels of pavement occurred the approximately evaluation results, this verifies this tester is feasible to attribute the skid-resistant performance of pavement. 7 tabs, 4 figs, 7 refs.
