1. Where should the hole be located for temping asphalt trucks? - ANSWER ✔
On both sides
6-10" higher than the bottom of the bed in the middle third of the truck
2. What is the master range for truck temperatures for both the plant and
roadway? - ANSWER ✔ +/- 30°
This is also the temp you base rejections off of
3. What is the criteria for temping asphalt trucks? - ANSWER ✔ Any single
trucks should be +/-25°
Average of 5 trucks should be +/-15°
4. Gyratory Specimens should be cooled to what temperature? - ANSWER ✔
77 +/-9°F
5. What is the process for drying cores? - ANSWER ✔ In the core dryer.
Weighing each time until the weight lost is less than 0.5 grams
6. When cooled the GMM samples should be no bigger than? - ANSWER ✔
1/4"
, (Stones that are bigger than 1/4" are excluded)
7. When the Orbital Shaker time is up and pressure is released for the GMM
how long do the samples sit? - ANSWER ✔ 10 +/- 1 minute
8. When do you fill the flasks for the GMM with water? - ANSWER ✔ Before
the 9 minute mark while sitting
9. When do you cap the flasks for the GMM samples and weigh them? -
ANSWER ✔ After 9 minutes has been reached on the timer and not to
exceed 11 minutes
10.What temperature of water is used throughout the GMM and GMB testing? -
ANSWER ✔ 77 +/- 2°F
11.The dry back procedure is used in what circumstance for the GMM -
ANSWER ✔ For mix designs to determine the GMM correction factor
12.When is the GMM dry back considered dry - ANSWER ✔ Weighed every
15 minutes and when the weight loss is less than 0.5 grams
13.Formula for GMM (MSG) - ANSWER ✔ Dry Sample ÷ (SSD or Dry
weight + Flask & Water - Flask & Water & Sample)
14.Roadway Density Cores Formula - ANSWER ✔ (GMB ÷ GMM) × 100
,15.If reheating the ignition sample is needed it is done at what temp? -
ANSWER ✔ 300°F +/- 9°F
16.Determining Mix Design Calibration Factor Formula - ANSWER ✔ Known
AC - (WL1 + WL2) ÷ 2
17.Determining 8 Sieve Correction Factor - ANSWER ✔ P-8[Solvent] - P-
8[Ignition]
18.Determining 200 Sieve Correction Factor - ANSWER ✔ P-200[Solvent] - P-
200[Ignition]
19.Tack Distributor without a calibration chart - ANSWER ✔ If they don't have
a calibration chart you can not use them to distribute tack
20.Application rate of tack for close graded mixes - ANSWER ✔ Normal: 0.02-
0.08 gal/yd^2
Must apply temperature correction factor
21.Calibration chart for distributor of tack - ANSWER ✔ Must be done by a
reliable and recognized firm
Chart provided to engineer prior to use
Know the temperature of asphalt cement being used for Tack coat
22.Measuring tack levels - ANSWER ✔ Stick the distributor before and after
spraying tack
Use calibration chart for Distributor to determine amount of asphalt in truck
before and after spraying
, 23.Formula for finding the length of a tacked road - ANSWER ✔ Find length of
tacked road
Station - station = station lineal feet
or
feet - feet = lineal feet
Then determine square yards of lineal feet
lineal feet X width / 9 = syds
24.Using what chart to calculate start and end readings to find how many
gallons were used - ANSWER ✔ Use distributor chart to calculate readings
Start reading 11/13 = 1319g
End 18/14 = 1140g
Gallons used = 179g
25.Using a temperature correction chart to find gallons used at 60F - ANSWER
✔ Correct gallons from 160°F to 60°F
Using a temperature correction chart
gallons at 60°F = gallons at 160°F X Correction factor
26.Calculating HMA placement yield for what reasons - ANSWER ✔
Structural design thickness
Adjusting cross-slope and grade
Calculate periodically and at the end of the day
27.HMA placement yield formula - ANSWER ✔ Amount used (lbs) / area
covered syds = yield
