WebFeb 11, 2024 · Application of Superelevation Bristol Motor Speedway One place you will see steep banking is at automobile racetracks. These tracks do not operate in winter, and so can avoid the problems of banking in winter weather. Drivers are also especially skilled, though crashes are not infrequent. For NASCAR fans, the following table may be of interest. WebPublic Works, Interim Road and Highway Standards, paragraph IX (c) limits the maximum superelevation rate (℮ max) for all roads is 10%. Table 1 shown below will be used to determine the superelevation rates for horizontal curves of a known radius, a known vehicles speed and a maximum superelevation rate of 10%.
