| Research Abstract |
The purpose of this study is to develop a road sliding friction prediction (μ) model considering influence of vehicles and road salt. Some field experiments have been carried out in order to formulate amount of salt scattered by passage vehicles and amount of salt that adheres to the surface of vehicles, and to investigate the relationship between μ and thickness of ice film on the road. Moreover, validity of the μ model has been verified through a comparison with field experiments. The results indicated that thickness of ice film, amount of salt and skid resistance on the road were satisfactorily calculated by theμ model. Consequently, theμmodel has made it possible to calculate the time variations of the snow/ice condition and skid resistance on a road after a road salt work
