TOTAL DISTANCE = 10,2004. Dev DENSITY > 98.3 lblcf Dey DENSIT max 124.5 lblcf Penso 0 Balance lines l) Swell factor A section of state freeway construction is out for bid that extends from station 148+00 to station 250+00, a distance of 10,200 ft or 1.93 miles. A bidding con- tractor has plotted up the cross sections from the plans and has computed the vol- umes of cut or fill between stations along the alignment. For each station along the alignment, the respective volume of cut or fill between that station and the preceding station is listed below. The bid documents state that if the cut and fill quanities do not balance, the state will provide either a borrow area containing suitable material or, alterna- tively, a waste disposal area to accommodate any excess, both 1500 ft off the alignment at station 250+00. Further, no borrow or waste will be permitted any. where else along the alignment. Soils tests along the alignment indicate that the average dry density of the in situ material in the cuts is 98.3 lb/cf. Furthermore, the technical specifications require that the fills must be compacted to 95% of modified Proctor test maxi- mam density. The modified Proctor test maximum density for the soils in the cut areas has been determined by soil tests to average 124.5 lb/cf. Plot a mass diagram reflecting the above given data on cross-section paper. Use a vertical scale of 1 in. = 250,000 Bcy and a horizontal scale of 1 in. = 500 ft. You must determine the average shrinkage factor from cut to fill to plot the mass diagram. (a) Do the quantities balance? If not, what is the excess excavation in bank cubic yard that must be wasted at station 250+00, or alternatively, what is the re- quired borrow quantity to be obtained at station 250+00 in bank cubic yards? (b) There is one set of hauls that will result in the most economical load-and- haul plan for the data and conditions stated. For each of these hauls, deter- mine the haul quantity in bank cubic yards and the haul distance in feet. (c) Construct a load-and-haul plan similar to that shown in Figure 8-11. For each haul, show the banl number, the quantity in bank cubic yards, and haul distance in feet. Also, show on the diagram the stations were cuts change to fills (and visa versa) and the stations for the balance points. Volume beveen stations Volume between stations Cut Bcy Cut, Boy 2 Station F.
