A sample of gravel from a stockpile weighs 15 lb (6.80 kg). After oven drying, the sample weighs 14.2 lb (6.44 kg). Calculate the moisture content of the sample.
A soil weighs 2500 lb/cu yd (1483 kg/m3) loose, 3100 lb/cu yd (1839 kg/m3) in its natural state, and 3650 lb/cu yd (2106 kg/m3) compacted. Find this soil’ s load factor and shrinkage factor.

How many truckloads of trucks hauling an average volume of 6 LCY (4.6 LCM) would be required to haul 1 million CCY (764 600 CCM) of the soil of Problem 7 to a dam site?
A rectangular ditch having a cross-sectional area of 24 sq ft (2.2 m2) is being excavated in clay . The soil’ s angle of repose is 35° and its swell is 30%. Find the height and width of the triangular spoil bank that will result from the trench excavation.
In making a field identification test of a soil, you find that less that 50% by weight of the coarse fraction is less than 1/4 in. (6mm) in size. The fine fraction of the soil exhibits low dry strength and gives a medium speed reaction to the shaking test. How would you classify this soil under the
A 1000-ft (305-m)-long pipeline requires an excavation 4 ft (1.2 m) wide to an aver-age depth of 5 ft (1.5 m). If the soil is dry common earth, what size spoil bank will be created by the excavation?
