Numerical Study on the Influence of Aggregate Size on Skid Resistance Performance of Porous Pavements

Porous pavements are often used as a means to improve skid resistance during wet weather. During the design and construction phases, porosity is often used as the single parameter representing porous pavement drainage capacity. However, it is insufficient to use this parameter to predict frictional performance on porous pavements because pavement mix with different aggregate sizes and yet having identical porosity values can yield significantly different skid resistance behaviors. This paper presents a numerical framework to analyze the influence of aggregate size on porous pavement skid resistance. It was found that despite having identical porosity, pavement mix with larger aggregates can provide higher permeability value, which consequently reduces the water film thickness on the pavement surface under a given rainfall intensity and relieves the hydrodynamic pressure buildup underneath the tire. Porous pavements constructed with larger-size aggregates for a given porosity are found to exhibit better skid resistance performance.
