Thanks to a specially developed coating made from a thin layer of aggregate, the surface of the CCL series has the same friction properties as conventional paving. The CCL series amply satisfies the criteria for a Skid Resistance Tester (SRT) value of ‘Highly resistant’, as well as complying with the NEN 7909 standard for skid resistance. While the road may appear very smooth during cold weather, it still satisfies this NEN 7909 standard, meaning you can cycle, drive or walk across it without any fear of slipping – as borne out by this independent field test.
