Asphalt 1 Test Review UPDATED ACTUAL Exam Questions and
CORRECT Answers
For asphalt mixes, it can be expected that approximately ______ to _____ percent of the
theoretical maximum density of the mix will be realized in the mix when it passes out from
under a vibratory paver screed - 70 to 80
If the air voids are above ______ percent for a SM-9.5A, the mix will be permeable to air and
water, and will not have the required durability - 7 to 8
If the mat is being laid down at a facer rate, then it can be rolled, the solution should be to
______ - Slow down the paver
Use larger, wider rollers.
Use more rollers
If traffic will pass over the end of the paving, a butt joint will be permitted, provided proper
compaction is achieved - False
If traffic will pass over the transverse joint, constructive slubbed wage, at least_____feet per inch
of pavement depth, ahead of end of the full debt payment to provide for proper compassion and
protection of the full depth pavement - 3
It typically takes ___t ow lengths (the length between the toe point, and the screed) after a
desired level is input for a screed to arrive at the new level - 5
Cold lane - A previously paved lane
, Hot lane - A lane being currently placed
Joint overlap - The width, that the hot lane overlaps the cold lane
The low-density areas on radiographic image are created by - This area is typically at the outer
edge of the cold lane taper in the joint overlap area
Extra material for compression - The material beyond the anticipated, final mat thickness
Put the typical compaction train in order - Screed.
Breakdown roller
Intermediate roller.
Finish roller.
Traffic
Indentations that remain in the surface of the mix after the rolling has been completed, are called
roller marks - True
Roughness or wash boarding is normally caused by improper operations of____ - A vibratory
roller
Rounded aggregate particles, offer more resistance to manipulation than angular particles do -
False
