Analysis of Rutting Index for Pavement Maintenance Based on Driving Safety on Surface Gathered Water Consideration
As a common distress in asphalt pavements, rutting is a primary influencing factor in cases of hydroplaning on rainy days. During hydroplaning events, steering stability performance of vehicles is drastically reduced. Based on analysis of the lateral stability and the steering stability of vehicles traveling on the water's surface while hydroplaning, this paper presents a theoretical analysis for rutting length and depth severity classification. Through creation of a vehicle dynamics model and the use of CarSim, the theoretical variations of lateral offset and lateral acceleration under different speeds were simulated. Through this analysis, it was found that when a vehicle's speed exceeds 80 km/h, the lateral offset and lateral acceleration of the vehicle will increase noticeably and will exceed the safety threshold. In addition, for a given rutting scenario, an interaction effect among rutting depth, rutting length, and vehicle speed is also apparent. Ultimately, a vehicle's lateral offset and lateral acceleration under different rutting depths are recommended for use as factors/indicators of rutting length.
