The authors discuss test results and analyses of tire hydroplaning, skid resistance, and other tire-pavement interactions. They address roadway and vehicle operator controls for mitigating hydroplaning and improving highway safety.

The conclusions are based on analyses of simulation, laboratory, and full-scale tests. Pavement cross slope, texture, rut depth, pavement wear, surface drainage, drainage-path length, precipitation intensity and duration, tire inflation, tread-pattern depth, tire construction, and vehicle traveling speed influence hydroplaning tendencies and vehicle control.

Other factors considered are tire rolling resistance, vehicle fuel consumption, noise, splash and spray, and headlight glare.

These results are applicable to highway pavement design, construction, and rehabilitation; tire construction; and vehicle operation.
