Webnot feasible to improve the horizontal curve radius, Table B-3-5-3b (e max = 0.08 m/m) is used to obtain the superelevation rate for new construction. The superelevation rate for new construction (e design) derived from Table B-3-5-3b (for R = 550 m and V = 110 km/h) is 0.079 m/m. As indicated in Table B-3-3a, f max is 0.10. See Point 2 in ...
