Q1). A circular curve is to be set out between two straight lines having intersection angle (1) is 2025', the station of the beginning of curve is (20-00) and the station of intersection point (Pl) is (21+80). Calculate station of PT, long chord, external distance and mid-ordinate. [10M] h Q2). Calculate volume of cut and fill, the elevation of natural ground shown on all nodes and design elevation is equal to 103 m, all dimension and elevations are in meter.
