摘要

The wear of bituminous pavements having a great expected wear resistance was studied on two places (in central and western Sweden) with different climate and with different aggregate petrography. The pavement types selected were made of different types of mixes with rolled in coated chippings, one dense-graded asphaltic concrete with high coarse aggregate content and one modified type of open-graded asphaltic concrete. Comparative measurements were made of surfacings of conventional dense-graded asphaltic concrete. The wear and the number of vehicles with studded tires were recorded during each winter season. The friction (BFC) was measured during spring, summer and autumn each year. The wear on the road in western Sweden was found to be 1,8 times the wear on the road in central Sweden. The results indicate that an increase in maximum particle size and in the content of coarse aggregates reduce the wear. The friction proved to vary with the season, the highest value appearing in spring and the lowest in summer. Considering the type of surfacing the friction shows an irregular dependence.
