FDOT ASPHALT PAVING LEVEL 2 EXAM
COMPLETE QUESTIONS AND DETAILED SOLUTIONS LATEST UPDATE THIS YEAR JUST RELEASED
Question 1: Determining a Target asphalt spread rate for non FC-5
mixes
Answer:
target spread rate = thickness x gmm (from mix design) x 43.3
(round to the nearest whole number)
Question 2: What is the tolerance for the asphalt spread rate
target?
Answer:
+- 5%
Question 3: How do you calculate the tolerance for the asphalt
spread rate target?
Answer:
Ex: Target Spread Rate = 165 lb/syds
Question 4: Formula for determining the asphalt spread rate for an
FC-5 mix?
Answer:
target spread rate = thickness x gsb (from mix design) x 40.5
(round to the nearest whole number)
Question 5: A prime coat being used on lime rock, sand-clay, shell,
and shell stabilized based have an application rate of what?
,Answer:
Limerock: greater than or equal to 0.10 gal/syd
Question 6: You do not test overbuild for density unless it is?
Answer:
Greater than one inch
Question 7: Where do you find approved tack products?
Answer:
On the FDOT Approved products list (APL)
Question 8: During night what is the tack you usually use?
Answer:
PG 52-28 or an approved emulsion
Question 9: What tack an you use during the day?
Answer:
Any kind of tack
Question 10: When determining the specification rate for 52-28 tack
you do what?
Answer:
Multiply the rate by 0.6
Question 11: What is the tack application rate tolerance?
Answer:
, +/- 0.01 gal/syd
Question 12: Step 1 for figuring the tack spread rate
Answer:
Find the length of the tack shot
Station - station = ft
Question 13: Step 2 for figuring the tack spread rate
Answer:
Find the square yards
Question 14: Step 3 for figuring the tack spread rate
Answer:
Use the distributor chart to find the gallons used
start 11/13 - 1319 gal
end 18/14 - 1140 gal
1319 - 1140 = gallons used
Question 15: Step 4 for figuring the tack spread rate
Answer:
Find the correction factor on the temperature sheet corresponding to the
correct liquid to convert the gallons to 60F
EX: 160F correction factor = 0.9756
Question 16: Step 5 for figuring the tack spread rate
Answer:
gallons used at 60F / syds = tack spread rate
