FDOT ASPHALT PAVING LEVEL 1 CORRECT
QUESTIONS AND ANSWERS SURE A+
✔✔Tack used at night - ✔✔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 - ✔✔+-0.01 gal/syd
✔✔Base, Structural, or dense graded friction - ✔✔0.03 minimum gal/syd on new
constructed
0.06 gal/Syd milled surface
0.08 gal/Syd concrete
✔✔Open Graded Friction Course - ✔✔0.05 gal/Syd newly constructed
0.07 gal/Syd milled
✔✔Perform the straight edge where in the road - ✔✔In the outside wheel path
✔✔Straightedge and joints - ✔✔Use the manual and place 1 inch over the joint and
measure
Allow 3/8 deficiency
✔✔Four things to know to calculate where cores lay - ✔✔Startinf station
Target yield
Width of road
Random tonnages
✔✔Formula to calculate core placement vertically - ✔✔2000 ÷ target yield x 9 ÷ width =
ft per ton of asphalt
then
Random number tonnage x ft per ton = ft away from starting station
, so
starting station + feet = core location vertically
✔✔Core placement horizontally - ✔✔Labeled as offset
Based on width of road
Feet away from edge of pavement
✔✔Can't core a road with a thickness of - ✔✔less than 1 inch
✔✔Can't core areas less than how many feet not on the mainland - ✔✔1000ft
✔✔Nuclear Gauges and PQIs are for - ✔✔Process control not a valid test for densities
for the DOT
✔✔ - ✔✔
✔✔ S to N - ✔✔Downstation
✔✔W to E - ✔✔Downstation
✔✔Stationing - ✔✔Starts at 0+00
✔✔Stationing Measurement - ✔✔1+00 is 100 feet
✔✔Straight Edge is the - ✔✔Measurement of Pavement smoothness with a 15 foot
4.573 m rolling straightedge
✔✔Straight Edge is used to - ✔✔identify problems
✔✔Random sampling - ✔✔Are random numbers generated usually by a VT for cores to
be extracted from the roadway
✔✔How often should you calibrate a Straight edge - ✔✔Calibrate at the start of each
working period
✔✔Using the manual straight edge you find what kind of spot to place the rolling
straightedge? - ✔✔Locate a flat area with the manual straightedge and place the rolling
straightedge next to the manual straightedge and the gauge should read 0
✔✔The 3/16 and the 3/8 shims go under which wheels during calibration - ✔✔The
outside wheels to measure the low and the center to measure the high. Gauge should
read 3/16 on the 3/16 shim and vice versa for the 3/8 shims. Make sure the center
wheel moves up and down freely.
