lIn Norway, most every car is equipped with tires having small steel studs to improve the friction between the tire and road during the winter season. These studded tires have an enormous wearing effect on ordinary asphalt pavement. <\ To improve the abrasion resistance, ~ started to apply high quality concrete instead of asphalt.
