Q1. A +2 percent grade on an arterial highway intersects with a -1 percent grade at station (5+357.28) at an elevation of 90m. If the design speed of the highway is 100 Km/h, determine the stations and elevations of the BVC and EVC, the elevation of each 30-m station, and the higlh point Q2. Determine the minimum length of a vertical curve if the grades are +4% and-200. Design speed is 120 km/hr. State assumptions used in solving this problem....

Problem 1 (15vpts) A proposed highway has two tangents of bearings N 75° 54' 36" E and N 53° 22' 30" W. The highway design engineer, attempting to obtain the best fit for the simple circular curve to join these tangents, decides that the external ordinate is to be 78.00 ft. The Pl is at station 65+43.21. Determine: (a) The external angle of the curve (A) (b) The radius of the curve (d) The station of the PC (f) The...
