1.The field engineer on a highway construction was left alone when the supplier of filling materials ask him on the total volume needed for the road embankment on station 10 + 040 to station 10 + 60. However the chief estimator is out for vacation and the estimate of filling materials is not yet available, therefore the engineer has no other option but compare the volume of the required material. The base width given on the plan is 12m and the height of fill at the left edge of the cross section is 1.5 m, at the centerline the fill is 2 m, and the right edge fill is 5 m. at station 10 + 060, the cross-section has centerline fill of 3 m, at the right edge the fill is 6 m, and the left edge the fill is 2.5 m. Assume even natural ground slope from left edge to the right edge of the cross section. How many trips will be ordered if the capacity of the dump truck is five cubic meters per trip? Side slope is 2:1 2. Compute the value of x from the cross section notes shown if the width of roadway is 9m. with side slope of 1:1. 5.42/40.92 + 4.25/ x/+0.60 3. Compute the side slope of the given cross-section shown 6.67/-1.84 -2.6 4.64/-0.40

Question
Transcribed Image Text:1.The field engineer on a highway construction was left alone when the supplier of filling materials ask him on the total
volume needed for the road embankment on station 10 + 040 to station 10 + 60. However the chief estimator is out for
vacation and the estimate of filling materials is not yet available, therefore the engineer has no other option but compare
the volume of the required material. The base width given on the plan is 12m and the height of fill at the left edge of the
cross section is 1.5 m, at the centerline the fill is 2 m, and the right edge fill is 5 m. at station 10 + 060, the cross-section
has centerline fill of 3 m, at the right edge the fill is 6 m, and the left edge the fill is 2.5 m. Assume even natural ground
slope from left edge to the right edge of the cross section. How many trips will be ordered if the capacity of the dump
truck is five cubic meters per trip? Side slope is 2:1
2. Compute the value of x from the cross section notes shown if the width of roadway is 9m. with side slope of 1:1.
