CE 3113 Spring 2009 Homework 9 Due 8 AM April 6, 2009 1. (15pts) A horizontal curve is to be designed for a two-lane road in mountainous terrain. The following data are known: Intersection angle: 45 degrees, tangent length = 500.00 ft, station of PI: 700+00.00, fs = 0.12, e = 0.08. Determine: (a) Design speed (b) Design elements (c) Station of the PC (d) Station of the PT (e) Deflection angle and chord length to the first 100 ft station 2. (15pts)  A proposed highway has two deflating angle of 45 degree, attempting to obtain the best fit for the simple circular curve to join these tangents, decides that the external ordinate is to be 50.00 ft. The PI is at station 60+00.00. Determine: (a) The central angle of the curve (b) The radius of the curve (c) The length of the tangent of the curve (d) The station of the PC (e) The length of the curve (f) The station of the PT (g) The deflection angle and chord from the PC to the first full station on the curve 3. (15pts) A simple circular curve exists with a degree of curve D =10º and e=0.08
