“…The multi-variable accelerated abrasion machine (MAAM) [21,22] is shown in Figure 2, developed by the Highway and Airport Pavement Research Center of Chang'an University, was selected to simulate the abrasion process of asphalt pavement. The MAAM drives the tire to reciprocate along two tracks through the circular movement of the crank arm.…”

To describe the skid resistance attenuation of asphalt pavement during its life cycle, this paper selected a multi-variable accelerated abrasion machine to simulate the abrasion process, and British Pendulum Number was selected to evaluate the skid resistance after various abrasive cycles. During the abrasion process, three factors influencing the skid resistance were considered, including aggregate types (diorite, limestone, granite, and basalt), nominal maximum aggregate size (NMAS), and gradations (dense, gap, and open). The results show that with increasing abrasion cycles, the skid resistance of asphalt pavement firstly decreases rapidly in the first abrasion stage (0–8000 cycles), then at a relatively gentle rate in the second abrasion stage (8000–20,000 cycles), and finally at the lowest rate in the third abrasion stage (after 20,000 cycles). The skid-resistance durability and stability of pavement are ranked as basalt > granite > amphibolite > limestone. Moreover, the effect of aggregate parameters on skid resistance is in the order: angularity > PSV > WSV > CSV. The skid resistance and its stability improve as NMAS increases. The pavement skid durability is in the order: SMA > OGFC > AC. In addition, the sizes of 16 mm, 13.2 mm, 9.5 mm, 0.6 mm, 0.3 mm and 0.15 mm are the critical sieve sizes to improve the skid resistance of asphalt pavement.
