4. A circular curve connects two tangents that intersect at an angle of 48°. The point of intersection of the tangents is located at station (948+67.32). If the design speed of the highway is 60 mi/h, 1) Determine the radius of the curve (use e=0.08); 2) Determine the starting and ending points of the curves; 3) Determine the deflection angles and chord length of whole stations for laying out the curve.
