Learning  Objective: Recognize the  principles  of  earthwork computations. 11-38. Earthwork  computations  are  the calculations  of  earthwork  volumes used to determine which of the following  factors? 1. The  final  grade 2. A balanced cut and fill 3. A plan for the most economical movement of material 4. All of the above 11-39. A cubic yard 3  feet  wide, in feet? 1. 1 2. 2 3. 3 4. 4 11-40. In  planning, is 3 feet long, and what height, which of the follow– ing conditions is NOT a state of condition  considered  when  com– puting  cubic  yards  of  material? 1. In place 2. Wet 3. Loose 4. Compacted 11–41. What term is used to describe a selected  layer  of  well–compacted soil that is placed in compacted lifts on top of the subgrade? 1. Crown 2. Base  course 3. Surface  course 4. Backslope 11–42. What term is used to describe the section of a ditch that extends from the outside of the shoulder to the bottom of the ditch? 1. Foreslope 2. Roadbed 3. Backslope 4. Travelway 11–43. A  cross-sectional  view  of  project prints  displays  the  slope  limits, the slope ratio, and the horizontal  distance  between  the centerline  stakes  and  the  shoulder stakes? 1. True 2. False Learning  Objective: Recognize the  principles  of  construction (grade)  stakes. 11-44. Which  of  the  following  describes grade  work? 1. Making cuts or limit of grade 2. Making cuts or definite  limit alignment fills with any and  alignment fills to a of grade and 3. Aligning  survey  stakes  on a  construction  project 4. Taking  the  ground irregularities  of  a  project and plotting them on a blueprint 11-45. A hub stake with a red or blue top is used for what type of grade work? 1. Finished 2. Rough 3. Profile 4. Alignment 11–46. A guard stake provides which of  the  following  services? 1. Warns  the  oncoming  traffic of  construction  ahead 2. Protects  construction  workers from traffic 3. Warns the operator that a flag is ahead 4. Provides a means of locating a  reference  point 84
