Transverse Pavement Grooving against Hydroplaning. I: Simulation Model

Abstract

Hydroplaning on a pavement surface with a film of water occurs when a vehicle reaches a critical speed and results in a loss of contact between its tires and the pavement surface. Pavement groovings, especially transverse pavement groovings, have been used in practice to reduce the occurrences of hydroplaning. This paper presents the development of a three-dimensional finite-volume model to simulate the hydroplaning phenomenon on pavements with and without transverse groovings. The theoretical considerations involved in the flow simulation model are described. The flow simulation makes use of fluid dynamics theories, utilizing the continuity equation, the Navier–Stokes equations, and the standard
