Question 1

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

Accepted Answer

100 feet

Answer

In US practice, one station equals 100 feet, so station 12+45.6 represents a distance of 1,245.6 feet from the origin.

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

Superelevation runoff is the specific length of roadway over which the outside lane is rotated from its normal 2% cross-slope to the full superelevation rate required for the 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 catch point is where the design slope (cut or fill) meets the natural ground, defining the outermost limit of earthwork at each cross-section.

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

Free haul is the contractually specified distance (commonly 500 or 1,000 feet) within which the contractor moves material for the included unit price, with additional payment (overhaul) required beyond that distance.

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

The mass diagram ordinate increases (rises) when moving through cut sections because excavated material is being added to the cumulative mass, and decreases through fill sections as material is consumed.
