An uneven or abnormal symmetry observed following the stakeout of a horizontal curve is usually an indication of a:

A. spiral curve.

B. curve embankment.

C. surveying error.

D. high design speed.

An offset stake is installed:

A. after the point of intersection.

B. for use as an undisturbed reference to a centerline stake.

C. one station after station 0+00.

D. when the surveyor uses GPS.

What is the distance that an offset stake is set from a centerline stake?

A. 2 feet

B. Half the distance from the beginning of curve to the point of intersection

C. 100 feet

D. The distance varies depending on the site

Offset stakes are installed to reduce the:

A. amount of construction staking necessary to maintain line and grade for the highway centerline.

B. quantity of vertical curves in a highway survey.

C. size of horizontal curves on a rural highway construction.

D. engineer’s design workload.

Vertical curves are used in highway construction to provide a:

A. point of intersection between survey stations.

B. method to go over rivers and streams.

C. gradual change between two adjacent grade lines.

D. fun highway to drive on.

When staking out a vertical curve, the point of intersection is:

A. the instrument setup point.

B. a point unable to be staked, as it is an extension of the legs of the curve tangents that is in the air or under the ground.

C. where the vertical and horizontal curves come together.

D. equally spaced between the beginning of the curve and the end of the curve.

The location of a vertical curve’s high and low points are important for:

A. drainage.

B. friction.

C. curve embankment.

D. station intervals.

The proposed route of a highway is typically chosen based in part on the:

A. result of the preliminary survey.

B. lengths of horizontal curves along the route.

C. last aerial photograph taken before construction begins.

D. height of the summation of vertical curves along the proposed route.

Except for changes in direction, highways are laid out in what station intervals?

A. 25 feet

B. 50 feet

C. 1000 feet

D. 100 feet

Clearing and grubbing are done to:

A. ensure the compensator in the automatic level is not stuck.

B. remove trees and vegetation along the proposed route of a highway or linear construction project.

C. clean the total station prior to staking out the highway centerline.

D. maintain a line of site around horizontal curves for faster drivers.

A marking on a slope stake of 3:1 indicates:

A. a total of 3 station intervals for every 100 linear feet.

B. three horizontal feet for every one foot of vertical change in grade.

C. an extremely steep class 3 slope embankment.

D. a vertical curve location marker.

The indication of a cut on a slope stake means the:

A. grade at the location of the stake needs to be increased in the amount equal to the indicated cut.

B. road must be kept flat in this area.

C. grade at the location of the stake needs to be reduced in the amount equal to the indicated cut.

D. ground is unstable in this area.

Layout for line and grade on highway construction projects is usually obtained:

A. one time.

B. two times.

C. when the contractor submits the pay request.

D. as often as necessary, but typically three or more times.
