Research by the Transport Research Laboratory (TRL) shows that the potential life of wearing courses, in terms of skidding resistance, may be as low as one year at high-stress sites. Added expenditure is needed to address this problem, but there is an alternative approach, which this article discusses. A single pass with a Klaruw K190 Anti-Skid Retexturing Machine is claimed to restore the optimal skidding resistance of certain polished aggregates immediately and improve their texture depth. Successive retreatments will achieve similar results, and the integrity of the wearing course should be almost unchanged. This will postpone the eventually required application of new materials. Therefore, skidding resistance can be maintained above investigatory level, to ensure safety, reduce accidents, and optimise the original investment in the wearing course. Even with a polishing interval of only one year, it should be possible to sustain skidding resistance for about five years.
