The ground makes a uniform slope of 5.2% from STA 8+890 to STA B. At station 8+890, the center height of the roadway is 4.13m fill. At the other station, the center height is 7.57m cut. If the finished roadway has a uniform grade of -2.6%. The side slope is 1:1. Assume that the center height and the height at the side are equal (isosceles trapezoid). The base of the roadway is 9m wide. a.) What is the stationing at B?
