Pavement and Geometric Design Criteria for Minimizing Hydroplaning. A Technical Summary
The authors have covered the empirical indications of hydroplaning as determined from hard data. Precise measurements of surface drainage were examined, and equations relating pavement texture and cross slope and rainfall intensity were developed. Vehicle control as related to variation in cross slope was simulated with the HVOSM simulation model. A determination of the deficiencies in existing surface drainage design methodology for sag vertical curves was conducted, and innovative solutions to these problems are presented. From a detailed study of state rainfall records a method is presented for determining a design rainfall intensity. Field studies of open-graded friction courses included water depths in simulated and natural rainfall, the effects of tire type, tread depth, inflation pressure, vehicle speed and accumulated traffic.
