Question 2 (29 points) You are asked to design a 24 ft wide two-lane rural roadway curvature for speed of 50 MPH. The s going to have a 1,500 feet radius with tangents intersecting at 40 degree angle (internal angle of the curve). The road has normal crown of 2% slope. The roadway is rotated the tide fres Assume the followings 8%, PI Station -65.00, Relative gradient A-1:200, BC Be Any Determine the following (Show your calculations) a) What is the station of B.C (PCY? b) Determine the Tangent run-out and Superelevation runoff length c) Develop a superelevation transition diagram for this roadway if revolved around getside are Label the diagram; B.C, stations, and superelevation. (use 1-50 feet for horizontal scale d) What is the superelevation rate at station 58-987 e) Suppose that you choose to use radius of 1,830 feet instead of the minimum radius, what is the appropriate rate of superelevation? Emax = 8percent
