Improved skid resistance on M20

Sections of the M20 in Kent now have improved skid resistance after a system from Klaruw was used on the motorway.

The GrooveTex system improves and restores surface skid resistance by creating micro longitudinal grooves using closely spaced diamond tipped saw blades at a predetermined width and depth. While being based on the well-known diamond grinding principle, Klaruw’s system has been engineered to provide innovations and improvements.

Unlike traditional grinding systems, it adjusts to and follows the profile of the surface. The surface levels after treatment remain the same as the surrounding surface avoiding the need for removal and reinstatement of road markings, road studs or ironwork.

Umesh Parajuli, senior pavement engineer at Balfour Beatty Mott MacDonald, which operates and maintains Area 4, said: “We have chosen the GrooveTex system for trials on the M20 to improve skid resistance and texture depth of the concrete surface through value management. This is a new technique in the UK which has potential for wider use on UK road networks following its successful application in Area 4. It is a good example of an innovative and sustainable process to improve safety of the road network that we can introduce with confidence to provide excellent value for money for our client.”

Martin Leech, managing director of Klaruw, added: “We continue to engineer cost-effective, carbon-reducing retexturing treatments that work in all weathers to restore the skid resistance of existing surfaces and extend asset life.”
