What formulas are used when solving for the total cut or fill volumes when given an earthwork
quantity table? - Answer✔Average end area formula L*(A1 +A2)/2
Pyramid formula (when there is a transition from one station to another where it goes from cut
to NO cut, or NO cut to cut etc. ***(ONLY WHEN IT IS SPECIFIED IN THE PROBLEM THAT THE
CROSS SECTIONS ARE TRIANGULAR IN SHAPE!)***
h*(area of base)/3
How to convert ft^3 to yards? - Answer✔1 ft^3 = 27yd
When calculating the volume given excavation depths/undercut depths. What do you need to
do in order to find the total volume? - Answer✔You must find the individual volumes of the
shapes, and then take the sum of those volumes to find the total. The volume is found by
multiplying the area by the depth.
What is a borrow pit? - Answer✔A borrow pit is a term used in construction for a hole, pit or
excavation that has been dug for the purposes of removing gravel, clay and sand used in a
construction project such as when building an overpass or embankment.
What is waste versus borrow in cut/fill calulations? - Answer✔Waste in when you have MORE
cut than fill.
Borrow is when you have LESS cut than fill.

What is the Superpave mix design method: - Answer✔Aggregate selection.
Asphalt binder selection.
Sample preparation (including compaction).
Performance Tests.
Density and voids calculations.
Optimum asphalt binder content selection.
Moisture susceptibility evaluation.
What is Ninitial in Superpavement design? - Answer✔The number of gyrations used as a
measure of mixture compactability during construction. Mixes that compact too quickly (air
voids at Ninitial are too low) may be tender during construction and unstable when subjected
to traffic. Often, this is a good indication of aggregate quality - HMA with excess natural sand
will frequently fail the Ninitial requirement. A mixture designed for greater than or equal to 3
million ESALs with 4 percent air voids at Ndesign should have at least 11 percent air voids at
Ninitial.
What is Nmax in Superpave design? - Answer✔The number of gyrations required to produce a
laboratory density that should never be exceeded in the field. If the air voids at Nmax are too
low, then the field mixture may compact too much under traffic resulting in excessively low air
voids and potential rutting. The air void content at Nmax should never be below 2 percent air
voids
What is the M/M/1 queue? - Answer✔M/M/1 queue represents the queue length in a system
having a single server, where arrivals are determined by a Poisson process and job service times
have an exponential distribution
-Arrivals occur at rate λ according to a Poisson process and move the process from state i to i +
1.
-Service times have an exponential distribution with rate parameter μ in the M/M/1 queue,
where 1/μ is the mean service time.
