What is strictly prohibited at the joints; excessive material should be removed.

• A. Longitudinal Joints
• B. Excessive Raking and Broadcasting Material
• C. Automatic Screed Controls
• D. Segregation

Answer: (B)

A clean, well-formed joint relies on controlling material at the edge so the two passes bond and compact smoothly. Raking or broadcasting extra asphalt right at the joint tends to create an uneven thickness, ridges, and potential dragging of material across the joint. This can push material into the joint edge, cause bleeding or a rough surface after compaction, and lead to a weak or segregated joint. Therefore any excess material at the joint should be removed to produce a flush, uniform joint that can be properly compacted and bonded with the adjoining lane. The other concepts—longitudinal joints, automatic screed controls, and segregation—are important in paving too, but they don’t describe the prohibited action at the joint as clearly as removing excess material does.
