FDOT ASPHALT LATEST
PAVING LEVEL 1
After you have finished coring the road you should do what to the
sample core - ANSWERS-Remove sample immediately to create
minimal disturbance
Damaged cores - ANSWERS-effect results
If the fresh asphalt is still to hot to core you should - ANSWERS-Cool
to be sampled with bags of ice
Application rate for open graded mixed - ANSWERS-OGFC(open
graded friction course FC-5): 0.045 gal/yd^2
Spread rate of tack formula - ANSWERS-Spread rate = gallons used at
60°F / syds covered
The breaking of emulsion is - ANSWERS-The water evaporating from
the asphalt cement
Binders - ANSWERS-Not PG 62-22

PAVING LEVEL 1
Cross slope frequency - ANSWERS-Every 100 feet if in range then
every 200 feet
Degree of accuracy for levels - ANSWERS-0.1 degrees
Tack used at night - ANSWERS-PG 52-28 which is multiplied the
specification rate by 0.6 to get your new target application rate.
Heated between 250 and 300°F
Tack allowed tolerance - ANSWERS-+-0.01 gal/syd
Base, Structural, or dense graded friction - ANSWERS-0.03 minimum
gal/syd on new constructed
0.06 gal/Syd milled surface
0.08 gal/Syd concrete
Open Graded Friction Course - ANSWERS-0.05 gal/Syd newly
constructed
0.07 gal/Syd milled
