Top 10 Questions for Paving Inspector Interview

1. What are the different types of paving materials and their properties?

• Asphalt: A mixture of bitumen, mineral aggregates, and sand. It is durable, flexible, and waterproof.
• Concrete: A mixture of cement, water, and gravel. It is strong, durable, and fire-resistant.
• Pavers: Individual units made of concrete, clay, or natural stone. They are durable, versatile, and come in a variety of colors and textures.

2. What are the common defects found in asphalt pavements?

• Cracks: Transverse, longitudinal, or alligator cracks caused by thermal stresses, traffic loads, or poor compaction.
• Rutting: Longitudinal depressions in the pavement surface caused by heavy traffic or poor drainage.
• Potholes: Circular depressions caused by water infiltration and freeze-thaw cycles.

3. How do you determine the thickness of a pavement?

• Non-destructive testing methods: Ground penetrating radar, seismic wave propagation, and falling weight deflectometer.
• Destructive testing methods: Coring and pavement thickness gauge.

4. What are the factors that affect pavement skid resistance?

• Texture: The roughness of the pavement surface.
• Aggregate type: The type and size of the aggregates used in the pavement.
• Traffic volume: The number and weight of vehicles using the pavement.

5. How do you conduct a pavement distress survey?

• Visual inspection: Identifying and classifying pavement distresses.
• Data collection: Recording the location, severity, and extent of distresses.
• Data analysis: Evaluating the data to determine the condition of the pavement and identify areas for repair.

6. What are the different methods of pavement repair?

• Patching: Repairing small areas of damaged pavement.
• Overlays: Applying a new layer of pavement over the existing pavement.
• Reconstruction: Removing and replacing the entire pavement structure.

7. What safety precautions should be taken when inspecting pavements?

• Wear appropriate safety gear (e.g., hard hat, safety glasses, reflective vest).
• Be aware of traffic and use proper flagging procedures.
