Using what chart to calculate start and end readings to find how many
gallons were used ---------CORRECT ANSWER-----------------Use distributor
chart to calculate readings
Start reading 11/13 = 1319g
End 18/14 = 1140g
Gallons used = 179g
Using a temperature correction chart to find gallons used at 60F ---------
CORRECT 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
Calculating HMA placement yield for what reasons ---------CORRECT
ANSWER-----------------Structural design thickness
Adjusting cross-slope and grade
Calculate periodically and at the end of the day
HMA placement yield formula ---------CORRECT ANSWER-----------------
Amount used (lbs) / area covered syds = yield
Do ARMI layers get tacked? ---------CORRECT ANSWER-----------------
Doesn't require tack
, Tack must be spread ---------CORRECT ANSWER-----------------Uniformly
Breaking of emulsion is the water evaporating from the asphalt cement
Traffic and Tack ---------CORRECT ANSWER-----------------Keep traffic off
tack, before it breaks and they go over it the tack is gone and no longer
uniform
Give the paver how far when checking the thickness a second time ---------
CORRECT ANSWER-----------------Give paver a minimum of 32 feet before
a second check to adjust
Thickness Probe should be set higher for what and by how much ---------
CORRECT ANSWER-----------------set higher for roll down of 20-25%
Target 1 inch probe set at 1 1/4 inches
Target 2 inches probe 2 1/2 inches
Yield VS Thickness ---------CORRECT ANSWER-----------------Better to
check yield constantly rather than thickness
After you have finished coring the road you should do what to the sample
core ---------CORRECT ANSWER-----------------Remove sample immediately
to create minimal disturbance
Damaged cores ---------CORRECT ANSWER-----------------effect results
