Asphalt and Concrete End of Module
Quiz Questions with Correct Answers
Asphalt Cement - ANSWERSIt is a bituminous material that is produced by distillation of
petroleum crude oil
Gyratory Crushers - ANSWERSa rock crusher in which a steel center cone rotates
eccentrically to crush the material against the outside cylindrical steel wall
Binder - ANSWERSThe asphalt cement material in a paving mix used to bind the
aggregate particles together, to prevent the entrance of moisture, and to act as a
cushioning agent.
Asphaltic Crushers - ANSWERSA composite material that is prepared in a hot-mix plant
and used for construction of highway, parking lot, or airfield pavements capable of
supporting high traffic load volumes and axle loads.
Hot Mix Asphalt - ANSWERSan asphalt paving mix produced in a plant where
aggregates are heated and dried and then combined with hot liquid asphalt cement and
place at high temperature
Leveling arms - ANSWERSTwo 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.
Lute - ANSWERSA 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.
Contraction Joints - ANSWERSJoints for the purpose of regulating cracking from the
unavoidable and unpredictable contraction of concrete.
Flights - ANSWERSMetal plates of various shapes placed longitudinally inside the shell
of a drum dryer or mixture. As the material moves through the drum, the flight first lift
the aggregate and then tumble it through the hot gases.
Friction course - ANSWERSThe top surface layer of an asphalt pavement, usually less
than 1 in. thick, to improve skid resistance and smoothness.
Stone Matrix Asphalt - ANSWERSA rut-resistant mixture that relies on stone-on-stone
contact, coupled with fiber or polymer-modified asphalt cement, to provide high-
strength, load-carrying capability.
