QUESTIONS AND CORRECT ANSWERS |
GRADED A+ | VERIFIED ANSWERS | JUST
RELEASED
The hole for temping asphalt trucks should be located where ---------
CORRECT ANSWER-----------------Hole located in the middle third of length
of truck; 6-10 inches above the bed
Temping asphalt on the top ---------CORRECT ANSWER-----------------At
engineer's discretion
Asphalt Temperature Master Range ---------CORRECT ANSWER-------------
----+-30; reject loads outside
Temp every load monitored if ---------CORRECT ANSWER-----------------Mix
within master range
Differes for a single load from established temp by +-25°F
Avg of five loads differes by +-15°F
Monitor until within tolerance
Tack Distributor without a calibration chart ---------CORRECT ANSWER-----
------------If they don't have a calibration chart you can not use them to
distribute tack
Application rate of tack for close graded mixes ---------CORRECT
ANSWER-----------------Normal: 0.02-0.08 gal/yd^2
Must apply temperature correction factor
, Calibration chart for distributor of tack ---------CORRECT 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
Measuring tack levels ---------CORRECT 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
Formula for finding the length of a tacked road ---------CORRECT
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
Straightedge and joints ---------CORRECT ANSWER-----------------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 ---------CORRECT
ANSWER-----------------Startinf station
Target yield
Width of road
Random tonnages
