A highway section, +2% , meet -8%at point with 52.0 m( GTs) at speed 120 Km/hr. Determine the elevation of the highest point on the pavement surface within this section.
Suppose a road passes through a reclaimed land and an existing land, what is the main concern regarding the design of pavements?
Wrong answer will be rated negative. The horizontal distance between its PVI and PVC is 150 meter. The elevation of PVI is 450.2 meter. The initial and final grades of the road are -4% and +3% respectively. Chainage of PVC is 1620 m. Based on the given set of information, determine the followings: i. Elevation of PVC. ii. The chainage of PVI. iii. Chainage and elevation of PVT. iv. Chainage and elevation of the lowest point of the sag curve.
