Abstract:

This research examines possible means of maintaining or restoring the skid resistance of Portland Cement Concrete pavements (PCCP) built with polish-susceptible aggregates. Several different methods of skid restoration were examined including shot blasting, transverse grooving and application of a rubberized asphalt chip seal (RACS). Neither of the first two methods appears capable of restoring skid resistance (as measured by ASTM E501) for any significant period although both markedly improve the rate of water removal. The RACS provided a long term improvement in skid resistance but its use should be limited due to concrete durability concerns.
