Q12:- A horizontal circular curve with radius of 265 m and deflection angle = 72 degrees is planned to design it on an undivided four-lane highway section has the design speed = 80 Km/hr and the normal crown slope on tangent -2%. Assume the following design information: Maximum relative gradient = 0.50%, side friction factor =0.12, lane width = 3.75 m, front overhang of vehicle =1.2 m, wheel base =12 m, lateral clearance per vehicle =0.9 m, track width on tangent =2.4 m, the elevation of the centerline is 49 m and the station of PI is 0+723. Calculate the pavement stations and elevations for the centerline and both edges at PC and PT points only?
