What can be done to enhance bonding at the joint during paving?

• A. Applying a bonding agent
• B. Increasing asphalt temperature
• C. Using thicker layers of HMA
• D. Switching to a different type of asphalt

Answer: (A)

Applying a bonding agent is essential for enhancing the bond at the joint during paving. A bonding agent serves as a crucial material that improves adhesion between the new layer of Hot Mix Asphalt (HMA) and the existing pavement. This ensures a strong and durable connection, which is vital for the longevity and performance of the paved surface. When the bonding agent is applied correctly, it helps to fill any voids or irregularities at the joint, thus creating a seamless transition between the old and new asphalt. This can prevent issues such as cracking or delamination that might arise from insufficient bonding. While increasing asphalt temperature might help in achieving better workability, it does not specifically enhance the bonding at the joint. Using thicker layers of HMA can provide strength and durability but does not directly address the issue of inter-layer adhesion. Switching to a different type of asphalt may not guarantee improved bonding at the joint, as the bonding agent's role is specifically tailored to promote adhesion in the paving process.
