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....
