Skid Resistance Attenuation of Asphalt Pavement Based on Multifactor Accelerated Wear Test

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

The Effect of Asphalt Concrete Micro & Macro Texture on Skid Resistance
Skid resistance and road condition are common indices of road safety; therefore providing adequate skidding resistance will reduce the incidence of road accidents. The surface macrotexture has a large effect on the characteristics of road surface skidding, which is the focus of this research. During the study, the mean texture depth of the road surface was measured, in order to determine the co...

In 1953, drivers in the United States became involved in 31,450 fatal and 1,302,000 non-fatal accidents. Many of these accidents were primarily the fault of the drivers involved, but a great number might have been minimized or prevented by safer highways. Although many factors are involved in the building of safety into highways, one of the more important items is the resistance of pavement sur...
