Which action should be performed on the joint area prior to paving to remove excessively loose material?

• A. Sweep the entire surface for debris
• B. Spray water on the joint area
• C. Clean the joint area
• D. Apply tack to the joint face

Answer: (C)

Removing excessively loose material from the joint area is about prepping the surface so the new pavement can bond properly. Cleaning the joint area does this by physically taking away loose aggregate, dust, and debris with a broom or blower until the surface is clean and dry. Spraying water isn’t ideal because moisture can interfere with subsequent bonding if not completely dried, and applying tack is something you do after cleaning to promote adhesion, not to remove loose material. So cleaning the joint area is the best action to prepare the surface before paving.
