PCC Paving Inspection LADOTD Exam Questions and Correct
Answers
Exam
FORMWORK & GRADE CONTROL (1-10)
1. What must a form's base width be equal to?
A) Equal to the pavement thickness
B) 0.8 of its height
C) 1.5 times the pavement thickness
D) 12 inches minimum
Answer: B
Rationale: LADOTD requires form base width to be 0.8 of its height for stability
during concrete placement and consolidation .
2. What is the maximum deviation a form section can have from required
alignment?
A) 1/4 inch
B) 1/8 inch
C) 1/2 inch
D) 3/8 inch
Answer: B
Rationale: Forms must not deviate more than 1/8 inch from required alignment
to ensure proper pavement geometry and joint alignment .
3. What is the tolerance for the top face of a form to deviate from true plane?
A) No more than 1/4 inch in 10 feet
B) No more than 1/8 inch in 10 feet
C) No more than 1/2 inch in 10 feet
D) No more than 3/8 inch in 10 feet
,Answer: B
Rationale: Top face tolerance is 1/8 inch in 10 feet to prevent surface
irregularities and ensure smooth pavement .
4. How much can the upstanding form leg vary from vertical?
A) 1/8 inch
B) 1/4 inch
C) 3/8 inch
D) 1/2 inch
Answer: C
Rationale: LADOTD allows up to 3/8 inch variation in form leg verticality for
proper load transfer .
5. How many pins per section of form are required for asphaltic concrete base?
A) 1 pin per section
B) At least 2 pins per section
C) At least 3 pins per section
D) 4 pins per section
Answer: B
Rationale: Each 10-foot form section on asphaltic concrete base requires at least
2 pins for secure anchoring .
6. How many pins per section of form are required for other bases (soil cement,
etc.)?
A) 1 pin
B) 2 pins
C) 3 pins
D) 4 pins
Answer: C
Rationale: Other base types require 3 pins per 10-foot section due to lower
stability than asphaltic base .
, 7. When must form release agent be applied to forms?
A) After concrete placement
B) Prior to placement of concrete
C) Only on the inside face after placement
D) At the end of each day
Answer: B
Rationale: Release agent is applied before concrete placement to prevent
bonding and facilitate form removal .
8. Where are forms oiled using a form release agent?
A) Only on the top edge
B) Inside face and top only
C) Inside face, top, and outside face
D) Only the bottom edge
Answer: B
Rationale: Release agent is applied to inside face and top—the surfaces
contacting concrete .
9. What is a "hub" in paving operations?
A) The center point of a curve
B) A reference stake from which all measurements are taken
C) The elevation point at the edge of pavement
D) The location of longitudinal joint
Answer: B
Rationale: A hub is a reference stake for establishing line and grade throughout
the paving operation .
10. Flange braces shall extend outward on the base at least how much of the
form height?
