What is the minimum radius of curvature allowable for a roadway with a 100 km/h design speed, assuming that the maximum allowable superele- vation rate is 0.12? Compare this with the minimum curve radius recommended by AASHTO. What is the actual maximum superelevation rate allowable under AASHTO recommended standards for a 100 km/h design speed, if the value of f is the maximum allowed by AASHTO for this speed? Round the answer down to the nearest whole percent.
