Introduction
This FDOT Asphalt Paving Level 2 Exam guide for the 2026/2027 academic year provides actual exam
questions and verified answers based on current FDOT Standard Specifications, Supplemental
Specifications, and CTQP training materials. It covers advanced concepts in asphalt technology, including
Superpave mix design principles, compaction theory, density requirements, smoothness specifications,
and quality control procedures essential for Level 2 certified technicians responsible for overseeing
asphalt paving operations on Florida highway projects.
Answer Format
All correct specifications interpretations, testing procedures, and quality control decisions must be
presented in bold and green, followed by verified rationales that reference specific FDOT Standard
Specifications sections, FM 5-T series testing methods, AASHTO standards, and CTQP guidelines
governing asphalt paving operations in Florida.
1. According to FDOT Standard Specifications Section 325, what is the minimum required field density
for asphalt pavement expressed as a percentage of the laboratory maximum theoretical density (Gmm)?
A. 90%
B. 92%
C. 93%
, D. 95%
C. 93%
Explanation: FDOT Standard Specifications Section 325.5.2 states that the field density of asphalt
pavement must be at least **93% of the laboratory maximum theoretical density (Gmm)** as determined
by AASHTO T 331 (Vacuum Sealing Method). This ensures adequate compaction to prevent premature
rutting and moisture infiltration [FDOT SS 325.5.2].
2. What is the primary purpose of tack coat in asphalt paving?
A. To provide skid resistance
B. To bond new asphalt lifts to existing surfaces
C. To reduce noise
D. To increase air voids
B. To bond new asphalt lifts to existing surfaces
Explanation: Tack coat is a light application of asphalt emulsion (typically SS-1 or CSS-1) applied to an
existing surface to ensure a strong bond between layers. Without proper bonding, delamination and
slippage can occur under traffic loading. FDOT SS 325.4.3 specifies application rates and coverage
requirements [FDOT SS 325.4.3].
3. Which test method is used by FDOT to determine asphalt content in plant-produced mix?
A. AASHTO T 164 (Solvent Extraction)
B. FDOT FM 5-T 250 (Ignition Oven)
C. AASHTO T 209 (Theoretical Maximum Specific Gravity)
D. AASHTO T 269 (Percent Air Voids)
B. FDOT FM 5-T 250 (Ignition Oven)
,Explanation: FDOT uses the Ignition Oven method (FM 5-T 250) to determine asphalt content in
asphalt mixtures. This method burns off the asphalt binder and measures the mass loss, providing quick
results with minimal hazardous waste compared to solvent extraction [FDOT FM 5-T 250].
4. What is the maximum allowable joint offset for longitudinal joints in FDOT asphalt paving?
A. 1 inch
B. 2 inches
C. 3 inches
D. 6 inches
A. 1 inch
Explanation: FDOT Standard Specifications Section 325.6.3 requires that longitudinal joints be
staggered by no more than **1 inch** between adjacent lifts to prevent weak planes and water infiltration.
Proper joint construction is critical for pavement integrity [FDOT SS 325.6.3].
5. Which Superpave performance grade (PG) binder is most commonly specified for Florida highway
projects?
A. PG 64-22
B. PG 70-22
C. PG 76-22
D. PG 58-28
C. PG 76-22
Explanation: Due to Florida’s high temperatures and heavy traffic, FDOT typically specifies **PG
76-22** binder, which resists rutting at high temperatures (76°C) and remains flexible at low
temperatures (-22°C). This is outlined in FDOT Standard Specifications Section 325.2.2 [FDOT SS
325.2.2].
, 6. What is the minimum temperature at which asphalt mix must be placed according to FDOT
specifications?
A. 225°F
B. 250°F
C. 275°F
D. 300°F
B. 250°F
Explanation: FDOT SS 325.5.1 states that asphalt mix must be placed at a minimum temperature of
**250°F** to ensure proper workability and compaction. Lower temperatures lead to inadequate density
and poor pavement performance [FDOT SS 325.5.1].
7. Which device is used by FDOT to measure ride quality (smoothness) of newly paved asphalt?
A. Nuclear density gauge
B. Profilograph
C. Dynamic cone penetrometer
D. Sand cone apparatus
B. Profilograph
Explanation: FDOT uses a **profilograph** to measure smoothness and calculate the International
Roughness Index (IRI). Acceptable smoothness is required per FDOT SS 325.8 to ensure rideability and
reduce vehicle operating costs [FDOT SS 325.8].
8. What is the primary cause of segregation in asphalt mix during placement?
A. Excessive compaction
