FDOT ASPHALT PAVING LEVEL 1 ACTUAL TEST
PAPER QUESTIONS AND ANSWERS SURE A+
✔✔When do you sample tack? - ✔✔During unloading when it reaches 1/3 of the load
✔✔What do you do first before sampling tack or binder? - ✔✔Discard the first gallon to
clear the line
✔✔What is the goal of sampling? - ✔✔To be done so randomly to avoid bias and creat
uniform representative samples
✔✔Lots are what size? - ✔✔2000 or 4000 tn
✔✔FC5 can only use what lot size? - ✔✔2000 tn
✔✔Sample sizes should weigh how much - ✔✔35 lbs
✔✔Sample box sizes should be what dimensions? - ✔✔12"x8"x4"
✔✔How do you sample an asphalt truck? - ✔✔In 3 different areas at least 12" down
✔✔What type of paper do you use for FC5? - ✔✔Silicone coated non stick paper (no
wax)
✔✔Where should the hole be located for temping asphalt trucks? - ✔✔On both sides
6-10" higher than the bottom of the bed in the middle third of the truck
✔✔What is the master range for truck temperatures for both the plant and roadway? -
✔✔+/- 30°
This is also the temp you base rejections off of
, ✔✔What is the criteria for temping asphalt trucks? - ✔✔Any single trucks should be +/-
25°
Average of 5 trucks should be +/-15°
✔✔Gyratory Specimens should be cooled to what temperature? - ✔✔77 +/-9°F
✔✔What is the process for drying cores? - ✔✔In the core dryer. Weighing each time
until the weight lost is less than 0.5 grams
✔✔When cooled the GMM samples should be no bigger than? - ✔✔1/4"
(Stones that are bigger than 1/4" are excluded)
✔✔When the Orbital Shaker time is up and pressure is released for the GMM how long
do the samples sit? - ✔✔10 +/- 1 minute
✔✔When do you fill the flasks for the GMM with water? - ✔✔Before the 9 minute mark
while sitting
✔✔When do you cap the flasks for the GMM samples and weigh them? - ✔✔After 9
minutes has been reached on the timer and not to exceed 11 minutes
✔✔What temperature of water is used throughout the GMM and GMB testing? - ✔✔77
+/- 2°F
✔✔The dry back procedure is used in what circumstance for the GMM - ✔✔For mix
designs to determine the GMM correction factor
✔✔When is the GMM dry back considered dry - ✔✔Weighed every 15 minutes and
when the weight loss is less than 0.5 grams
✔✔Formula for GMM (MSG) - ✔✔Dry Sample ÷ (SSD or Dry weight + Flask & Water -
Flask & Water & Sample)
✔✔Roadway Density Cores Formula - ✔✔(GMB ÷ GMM) × 100
✔✔If reheating the ignition sample is needed it is done at what temp? - ✔✔300°F +/-
9°F
✔✔Determining Mix Design Calibration Factor Formula - ✔✔Known AC - (WL1 + WL2)
÷2
✔✔Determining 8 Sieve Correction Factor - ✔✔P-8[Solvent] - P-8[Ignition]
✔✔Determining 200 Sieve Correction Factor - ✔✔P-200[Solvent] - P-200[Ignition]
