Which two equipment types are used for compaction in asphalt paving?

• A. Vibratory Screed on Paver and Rollers
• B. Paver and Hand Tamper
• C. Finisher and Broom
• D. Pavement Breaker and Drill

Answer: (A)

Compaction in asphalt paving relies on smoothing and densifying the mat as it is laid, then finishing the density with rollers. The vibratory screed on the paver provides the initial compaction and level of the asphalt as the mat is laid down, shaping the thickness and helping to consolidate the mix early. After the mat is placed, rollers apply the main compaction to reach the required density and surface smoothness, with different roller types used to achieve the desired finish and density.

That combination—vibratory screed on the paver for the initial compaction and rollers for the final densification—is the standard approach. Tools like a hand tamper, finisher with a broom, or pavement breaker and drill are used for patching, finishing, cleanup, or breaking/removing material, not for compacting the paved surface.
