CIVE1206: Roads and Transport Tutorial

Problem 1:

Table 1 given in page 2 shows the calculated cut and fill areas at different stations along a

 proposed route. The distance between the stations is 100 m. The shrinkage factor for the soil

at the site was determined to be 15%. The agreed Free Haul Distance (FHD) is 200m and the

Limit of Profitable Haul (LPH) was determined to be 500 meter. Based on the giveninformation, answer the following questions:

a)  Complete the calculations (gray coloured cells in Table 1 given in page 2) required to

develop the mass-haul diagram.

 b)  Plot the mass-haul diagram.

c)  On the plotted mass-haul diagram, show the free-haul distance between Station 0 and

a point at 750m from Station 0. Also determine the volume of material between the

above two points that can be hauled free of cost.

d)  On the plotted mass-haul diagram, show the profitable haul distance between Station

0 and a point at 750m from Station 0. Also determine the quantity of material that can be profitably hauled between the above two points.

e)  Determine the amount of materials that needs to be wasted and borrowed between

Station 0 and a point at 750m from Station 0.
