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...
متن کاملThe 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...
متن کاملLimitations of Using Skid Number in Accident Analysis and Pavement Management
Pavement frictional characteristics are commonly determined by conducting skid tests in accordance with ASTM Standard E274. The results of these tests [skid number (SN)] are used in ranking roads to establish construction priorities and to estimate tirepavement friction in accident analysis. The role of SN in these two applications is addressed. There are serious limitations constraining the us...
متن کاملEvaluation and Validation of a High-speed Multi- Function System for Automated Pavement Condition Survey
Manual surveys still represent the most widely used means for inspecting and evaluating pavements. Manual rating of pavements through windshield surveys to identify the types of surface cracking and other distresses leads to relatively slow evaluation. Furthermore, the survey crew must sometimes physically be in the travel lane to evaluate the pavement, exposing themselves to hazardous conditio...
