Two types of asphalt plants used in New Jersey are drum mix and batch mix solute minimum lay down temperature for asphalt (bituminous) concrete T F nominal maximum aggregate size T F plants. T F 12. The ab is 125 T F 13. Compaction of hot mix asphalt on a soft yielding subgrad e will not affect density and/or air voids t is not necessary to coordinate the paver speed and truck deliveries uniformly, during paving operations. T F 14. I T F he recommended spreading temperature of bituminous concrete depends on the base temperature and thickness of the mat. 15. T Generally, the minimum rolling time is 4 minutes for thin bituminous concrete mats to 15 minutes for thick mats 2-4\" in depth. T F 16. T F 17. Petroleum solvents should be used to clean tools, paving machine hopper and screeds, rollers and hand tools. T F 18. A nuclear gauge is used to measure asphalt concrete density in place. 19.

Improved subsurface drainage and maintenance is not significant as to TF is 50°F T F asphalt, low temperatures and lack of asphalt in the matrix. pavement longevity temperatures, high asphalt content in the mix, type of aggregate used in the T F T F 22. Pave ment rutting can be related to excessive tire load and repetitions, high mix and improper compaction. rock of the same thickness and asphalt content. repair all deteriorated areas and improve the subdrainage. stick to the roller and blue smoke will emit from the loaded dump truck. 23. River gravel is often used in bituminou s concrete and is just as good as trap 24. The first steps in overlaying a deficient pavement with moderate defects is to T F 25.
