FS Route and Transportation Surveys 3

Question 1

In US route surveying practice, one 'station' along a centerline represents a horizontal distance of:

Accepted Answer

100 feet

Answer

10 feet

Answer

50 feet

Answer

1,000 feet

Question 2

Superelevation runoff in highway design refers to:

Accepted Answer

The length of roadway needed to transition from a normal crown section to a fully superelevated cross-section

Answer

Drainage flow across a superelevated roadway surface

Answer

The maximum rate of superelevation permitted by AASHTO standards

Answer

The difference in elevation between the high and low edges of a superelevated curve

Question 3

A slope stake (catch point) in earthwork field surveying marks:

Accepted Answer

The point where the proposed cut or fill slope intersects the existing natural ground surface

Answer

The highest elevation point within a cut section

Answer

The centerline of the proposed roadway at each station

Answer

The edge of the construction right-of-way boundary

Question 4

In highway construction economics, the 'free haul distance' is defined as:

Accepted Answer

The specified distance within which earthwork can be moved without extra compensation beyond the excavation unit price

Answer

The distance over which material can be moved by gravity without equipment

Answer

The total volume of material that can be moved at no additional cost

Answer

The distance from the borrow pit to the nearest fill section

Question 5

On a mass diagram, an ascending (rising) portion of the curve indicates:

Accepted Answer

Cut sections where excavation is generating a surplus of material

Answer

Fill sections where material is being consumed

Answer

A balance point between cut and fill

Answer

Wasted or waste material that must be removed from the project

Question 6

A spiral (transition) curve is inserted between a tangent and a circular curve in highway design to:

Accepted Answer

Provide a gradual change in curvature and allow smooth superelevation transition

Answer

Connect two tangents that are too close together for a simple circular curve

Answer

Replace the need for superelevation on low-speed roads

Answer

Connect two circular arcs of different radii turning in the same direction

Question 7

In earthwork economics, 'overhaul' is best defined as:

Accepted Answer

The transportation of excavated material beyond the free haul distance, billed per station-yard or ton-mile

Answer

The cost per cubic yard of excavating material beyond the design depth

Answer

The volume of material that must be wasted beyond the project limits

Answer

Material moved from a borrow area located outside the right-of-way
