Asphalt Pavement UPDATED ACTUAL Exam Questions and
CORRECT Answers
Hot bins - Bins on an asphalt batch plant used to store dried aggregates prior to proportioning
and mixing with the asphalt cement.
Hot elevator - A bucket elevator used to carry hot, dried aggregate from the dryer to the gradation
unit of an asphalt batch plant.
Hot oil heater - A heater for increasing the temperature of heat transfer oil. The heated transfer
oil maintains the temperature of stored liquid asphalt, or mixed asphalt concrete that has been
placed in storage silos.
Leveling Arms - Two long arms extending forward from each side of the asphalt paver screed
and attached to tow points on the tractor. This mechanical connection enables the screed to float
on the asphalt mix during placement.
Leveling course - A new layer of asphalt mix placed over a distressed roadway or unbound base
to improve its profile prior to resurfacing.
Lift (mat) - A layer of asphalt mix separately placed and compacted.
Lute - A type of rake used to smooth out minor surface irregularities in the hot asphalt mix
behind the paver. It has a straight-edge side and a toothed side.
Nominal maximum aggregate size (NMAS) - One size larger than the first sieve that retains more
than 10% of the aggregate mass.
