During the rough grading phase of construction, you discovered a 12-inch water pipe crossing the roadway at Station 18+50. The elevation on top of the pipe is 730.92 ft. You have communicated this information to the project engineer who has asked you to calculate and lay out an equal tangent vertical curve so that the top of pavement passes 36 in above the top of the water pipe with the following design elements: Vertical curve beginning at Station 16+50 (Vertical Curve #2) G1 = 8.75% G2 = -1.50%. Calculate the total length (in feet) of the equal tangent %3D %3D vertical curve #2.

You are going to design a circular curve in a rural road segment where the design vehicleis a passenger car of operation speed is 90 km/h. The width of the lanes of the proposedroad is 3.5m. Based on a survey at the proposed site, it has been found that a multi-storiedbuilding is located towards the inside of the curve at 10 m from the centerline of thehighway. Considering perception reaction time as 2.5 s design the horizontal curve (Rdesign,edesign and fdesign) for that road segment. Record the radius and respective safe sight distancein the tabular format while selecting design radius (word table), plot them in Excel graphand find the Rdesignfor the safe sight distance. If there is no superelevation, what would bethe alternative arrangement?
