Effect of Pore Network Characteristics on Pervious Pavement Skid Resistance using XRCT-based Modelling

Abstract

The functional performances of the pervious pavements such as hydraulic and frictional performances are considered as two essential elements influencing the successful application and implementation of pervious pavement in the field starting from design till maintenance. These performance characteristics are greatly influenced by the pore network properties of the pervious pavement structures. In addition to this, the variability in the pore network and skid resistance characteristics of the batch mixed pervious pavements are also not investigated. Therefore, this paper attempts to evaluate the effect of pore network properties on skid resistance of the batch mixed pervious concrete samples using the Digital Image Processing (DIP) algorithms and Fluid-Structure Interaction (FSI) based numerical tools. This is followed by the statistical analysis on the determination of the minimum number of test samples for batch mixed samples. Overall, the present study will help in understanding the variability of pore network and skid resistance characteristics of the pervious concrete mixtures in its design and maintenance stages.
