,A) 2%
B) 3%
C) 4%
D) 5%
Answer C: 4%
Rationale: Air voids in a Superpave mix design are typically targeted at 4%.
5. A standard lot is composed of 5 sublots and 4 cores per lot.
A) True
B) False
Answer B: False
Rationale: A standard lot is not composed of 5 sublots and 4 cores per lot.
6. Who cuts the density cores used for verification testing?
A) The Department
B) The Contractor
C) A third-party lab
D) The Engineer
Answer B: The Contractor
Rationale: The contractor cuts the density cores used for verification testing.
7. Which of the following is NOT typically used as an asphalt binder in FDOT mix designs?
A) PG 52-28
B) PG 58-22
C) PG 62-22
D) PG 76-22 (PMA)
Answer C: PG 62-22
Rationale: PG 62-22 is not typically used as an asphalt binder in FDOT mix designs. Common binders include
PG 52-28, PG 58-22, PG 76-22 (PMA), and PG 82-22 (PMA).
8. What is the minimum recommended temperature for compacting asphalt mat in cold weather
(below 50°F)?
,A) 200°F
B) 250°F
C) 280°F
D) 320°F
Answer C: 280°F
Rationale: 280°F is the typical minimum compaction temperature to achieve density before the mix cools
too much.
9. What is the maximum allowable time between truck discharge and initial compaction in hot
weather (above 85°F)?
A) 15 minutes
B) 30 minutes
C) 45 minutes
D) 60 minutes
Answer B: 30 minutes
Rationale: In hot weather (above 85°F), the maximum allowable time between truck discharge and initial
compaction is 30 minutes.
10. For bridge approach slabs, the 15-foot manual straightedge should be set so ____ is on the bridge
deck.
A) 1 inch
B) Exactly 1/2 of the straightedge
C) The entire straightedge
D) None of the above
Answer A: 1 inch
Rationale: For bridge approach slabs, the 15-foot manual straightedge should be set so 1 inch is on the
bridge deck.
11. For the first transverse joint on a project, place the ____ on the new pavement while overlapping
the transverse joint by one inch.
A) 4-foot level
B) 15-foot manual straightedge
C) Rolling straightedge
, D) All the above
j j j
Answer B: 15-foot manual straightedge j j j j
Rationale: The 15-foot manual straightedge is placed on the new pavement while overlapping the transverse
j j j j j j j j j j j j j j
j joint by one inch. j j j
12. When calibrating to check the low side of the rolling straightedge:
j j j j j j j j j j j
A) Place shims under the outer wheels
j j j j j j
B) Place the rolling straightedge on a surface that looks flat
j j j j j j j j j j
C) Place a 3/16 inch shim under each outside wheel; the gauge should read zero on both sides of the gauge
j j j j j j j j j j j j j j j j j j j j
D) Place shims under the center wheel
j j j j j j
Answer C: Place a 3/16 inch shim under each outside wheel; the gauge should read zero on both sides of
j j j j j j j j j j j j j j j j j j j
j the gauge j
Rationale: For low-side calibration, place a 3/16 inch shim under each outside wheel; the gauge should read
j j j j j j j j j j j j j j j j
j zero on both sides. j j j
13. When calibrating to check the high side of the rolling straightedge:
j j j j j j j j j j j
A) Place shims under the outer wheels
j j j j j j
B) Place a 3/16 inch shim under the center wheel; the gauge should read zero on both sides of the gauge

C) Place the rolling straightedge on a surface that looks flat
j j j j j j j j j j
D) Place shims under the outer wheels and center wheel
j j j j j j j j j
Answer B: Place a 3/16 inch shim under the center wheel; the gauge should read zero on both sides of the
j j j j j j j j j j j j j j j j j j j j
