Study on the Attenuation of Long-Term Skid Resistance of Asphalt Mixtures under Aeolian Sand Conditions.

As shown in Figure 5 , overall, four types of asphalt mixture specimens were produced in the pre-abrasion period: the SMA-graded type of mixture anti-skid performance is better than the AC-graded type of asphalt mixture, under the action of the wind accumulation of sand; with the increase in the number of times of abrasion, the anti-skid performance has shown a decreasing trend, when the density of sand accumulation is smaller, the BPN value decreases significantly.
