Title:

Analysis of Effectiveness of Longitudinal Grooving Against Hydroplaning

Abstract:

Longitudinal pavement grooving has been applied in highways to reduce occurrences of hydroplaning at accident prone locations. However, to date there has not been a systematic study of its effectiveness against hydroplaning. This paper presents a numerical model to simulate the hydroplaning phenomenon and conducts a systematic study on the effectiveness of various designs of longitudinal grooving against hydroplaning. First, the important parameters of the numerical simulation model are briefly described. Next, the effects of pavement groove dimensions on hydroplaning potential are analyzed. Groove dimensions are found to have significant effects on the effectiveness of a grooving design against hydroplaning.Finally, the significance of the applications of longitudinal pavement groovings in highways is discussed, giving reference to the current practices in various states.
