The contribution of surface macro-texture to effective and efficient drainage is well established. Failure of a pavement to discharge surface water will impact wet skid resistance and road safety. In addition there may be also significant potential for physical damage to the surface due to freeze/thaw and/or hydraulic forces applied to pockets of trapped water. This paper reports the findings of a study which demonstrates the potential of models of surface micro-topography to highlight and delineate areas of water containment. In this study, triangular irregular networks (TIN) were constructed for a range of remotely captured surface textures. They were combined with raster overlays and depth classified in a proprietary spatial information system to highlight potential areas of water lock-in. Critical entrapment depths are specified for the full range and diversity of textures. The TIN data may be used to gauge the potential susceptibility of a pavement to surface breakdown and trigger appropriate remedial measures.
