ASPHALT EXAMS SET FULL QUESTIONS
AND COMPLETE SOLUTIONS
●● A transverse joint should be compacted in the longitudinal direction
unless the roller cannot compact the joint because site restriction then it
is permissible to be compacted transversely
Answer: False
●● An approximate "rule of thumb" is for every _______ percent
increase in air voids above (6 to 7%) about _______ percent of the
pavement life may be loss
Answer: 1 and 10
●● An end plate (or end gate or edger plate) is attached to the end of the
screed to restrict the outward movement of the mix around the end of the
screed
Answer: True
●● An extremely high paver speed - more than ______, for thick lift,
may cause a lack of responsiveness of the screed
Answer: 83 feet per minute
●● Butt joints are acceptable when traffic will not pass over the joint
prior to the next paving operation
, Answer: True
●● Durang, rolling, rolling wheels, are kept moist with water, and only
enough fuel oil to avoid picking up material
Answer: False
●● Elimination of segregation is the responsibility of
Answer: Those who produce and lay assault mix
State Highway Departments who approve the design of the mix and
inspect the final product
Manufacturers who designed the market machinery for the paving
industry.
●● 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
Answer: 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
