Before compacting, how should the newly spread HMA be aligned at the joint?

• A. It should be above the existing pavement level
• B. It should be even with the existing pavement level
• C. It should be below the existing pavement level
• D. It should be randomly arranged

Answer: (B)

When aligning the newly spread Hot Mix Asphalt (HMA) at the joint, it is essential for it to be even with the existing pavement level before compacting. This approach promotes a smooth transition between the new and existing pavement, ensuring proper bonding and reducing the risk of future cracking or damage at the joint.

Achieving an even level is crucial for maintaining the overall integrity of the pavement surface and allows for effective compaction. If the new HMA is too high, it could lead to a ridge that becomes a weak point under traffic loads. Conversely, if it is too low, it might result in voids or inadequate support, potentially leading to deformation or structural failure over time. Random arrangement could compromise these factors significantly, leading to long-term performance issues. Therefore, ensuring that the new asphalt aligns even with the existing pavement is the ideal practice for proper installation and longevity of the paved surface.
