Field investigation of skid resistance degradation of asphalt pavement during early service

Investigation of Clay Balls in Asphalt Pavement

Clay ball is a pavement surface defect which refers to a clump in which clay or dirt is 8 mixed with hot asphalt mixture. Clay ball is typically caused by a combination of aggregate 9 contamination of clay or soil, high aggregate moisture, and low production temperature at the 10 asphalt plant. It usually appears a few weeks or months after paving under traffic load, after being 11 liquefied an...

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...

Skid Characteristics of Pavement Surfaces in Indiana

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...
