Section 1: Pavement Fundamentals and Condition Assessment
1. What is the primary purpose of pavement preservation treatments?
A. To replace the entire pavement structure
B. To increase pavement thickness substantially
C. To extend pavement service life by slowing deterioration
D. To eliminate the need for drainage systems
Rationale: Pavement preservation treatments protect pavement that
is still structurally serviceable. They slow deterioration, improve
surface characteristics, and delay more expensive rehabilitation or
reconstruction. They do not correct every structural deficiency.
,2. Which pavement distress is characterized by interconnected cracks
forming a pattern resembling chicken wire?
A. Edge cracking
B. Alligator cracking
C. Block cracking
D. Reflective cracking
Rationale: Alligator cracking consists of interconnected cracks forming
small polygons, resembling reptile skin. It commonly indicates fatigue
caused by repeated traffic loading, inadequate structural support, or
weakened pavement layers.
3. Before selecting a pavement treatment, what should a contractor
evaluate first?
A. The color of the existing pavement
B. The number of workers available
C. The brand of sealant being used
D. The pavement's condition, distress type, and structural integrity
Rationale: Treatment selection depends on the type, severity, and
extent of pavement distress. A surface treatment may be suitable for
,oxidation or minor cracking but will not resolve significant structural
failure. Proper evaluation prevents ineffective treatment selection.
4. What is the primary function of a pavement subgrade?
A. To provide the final wearing surface
B. To prevent all surface water from evaporating
C. To support the pavement structure and distribute applied loads
D. To replace the need for a base course
Rationale: The subgrade is the prepared soil foundation beneath the
pavement structure. It supports the base and pavement layers and
helps distribute traffic loads. Weak or unstable subgrade conditions
can contribute to rutting, settlement, and cracking.
5. Which pavement distress is commonly associated with water
entering the pavement structure and weakening support?
A. Surface polishing
B. Potholes
C. Minor oxidation
D. Faded pavement markings
Rationale: Water infiltration can weaken pavement layers and reduce
support. Combined with traffic loading and material deterioration,
, this can cause pieces of asphalt to break away and form potholes.
Drainage correction and removal of failed material may be necessary
before applying a surface treatment.
6. What does pavement oxidation generally cause?
A. Increased flexibility of the asphalt binder
B. Complete restoration of the original pavement structure
C. Hardening and embrittlement of the asphalt binder
D. Elimination of pavement cracking
Rationale: Oxidation occurs as asphalt binder reacts with oxygen and
ages. The binder becomes stiffer and more brittle, increasing
susceptibility to cracking and raveling. Appropriate preservation
treatments may help protect the surface, depending on the
pavement's condition.
7. Which condition most strongly suggests that a pavement requires
structural rehabilitation rather than a simple surface treatment?
A. Slight fading of pavement markings
B. Minor surface oxidation
C. Isolated hairline cracks
D. Extensive deep rutting and widespread fatigue cracking
