Which of the following uses for WMA is not an advantage of using WMA over HMA?

WMA (Warm Mix Asphalt) technology offers several advantages over traditional HMA (Hot Mix Asphalt), particularly in improving workability and reducing temperatures during the paving process. One of the noted advantages of WMA is its ability to facilitate paving in cooler weather, which can enhance the flexibility of construction schedules.

While areas that require more hand work might benefit from the properties of WMA, this does not represent a specific advantage of using WMA over HMA. Handwork typically refers to manual placement and finishing tasks that may be necessary in intricate areas or at edges. Both WMA and HMA can be used in these situations; however, the choice of material may not directly impact the ease of handwork.

In contrast, WMA has compelling benefits when it comes to paving in cold weather, longer haul distances (as it can maintain workability and temperature better during transport), and enhanced compaction properties due to its lower initial temperatures. Thus, the use of WMA is particularly valued for improving efficiency and performance in various environmental and logistical contexts.
