The standard gradation of asphalt concrete for skid-resistant pavement is presented, the skid-resistance and stripping phenomena of open-graded asphalt concrete is discussed, and the properties of gap-graded dense asphaltic concrete is reviewed. The results of tests on open-graded asphalt concrete and of a survey of stripping in pavement structure due to permeated water are tabulated. The results are also presented of comparisons of abrasion resistance between continuous and gap grading. The abrasion loss on an experimental pavement during winter is illustrated graphically. In Japan, open graded dense asphaltic concrete is used in general areas, while gap graded dense asphaltic concrete which has high filler/asphalt ratio is used in snowy areas. Gap grading is recommended for the mixture, thus ensuring durability, abrasion resistance, and comparatively high skid resistance.
