Earthwork Exam 1 –Questions With Well Detailed
Solutions
Station cross section problem Right Ans - ((EA + EA)/2) x (L/27)
Station Right Ans - horizontal distance of 100 ft
Plan view Right Ans - horizontal alignment
Profile view Right Ans - vertical plane cut through the centerline of the
work
Cross section view Right Ans - vertical section at right angles to the
centerline of the work
Stripping Right Ans - removing upper layer of amterial before excavation
In situ Right Ans - natural undisturbed in place soil or rock
Cohesive material Right Ans - soil having strong interparticle attractive
forces
Plasticity Right Ans - capability of being molded
Shrinkage Right Ans - volume reduction usually occurring when soils or
rock are subjected to moisture or mechanical compaction
Swell Right Ans - a volume increase occuring when soils or rocks are
excavated and loosened from the earths crust
Five major types of soil Right Ans - gravel, sand, clay, silt, and organic
matter
liquid limit Right Ans - the water content at which a soil passes from the
plastic to the liquid state. High LL values are soils with high compressibility
optimum water content Right Ans - amount of water required for a given
soil to reach maximum density
