Twenty-five experiments of one-dimensional shallow thin-surface flow on wide carriageway pavements are investigated, undertaken as part of wider investigations to avoid aquaplaning. Analysis of their predictive equations for surface water depths are assessed, along with informative background papers. Issues regarding rainfall intensity and the macrotexture structure of pavement materials and their interrelationship are considered. Current international best-practice guidance is contrasted and observations for the practising highway engineer are provided, as well as recommendations for future research.
