What might happen if an asphalt mix does not include anti-stripping agents in wet conditions?

When an asphalt mix does not include anti-stripping agents, the bond between the asphalt binder and the aggregate can be negatively affected, particularly in wet conditions. Anti-stripping agents are designed to enhance the adhesion between the asphalt and the aggregates, ensuring that moisture does not penetrate and weaken the bond.

In wet situations, water can infiltrate the interface between the asphalt and the aggregate. If anti-stripping agents are absent, this can lead to stripping, where the asphalt binder pulls away from the aggregate, causing a loss of bond. This results in diminished performance of the pavement, potentially leading to surface distress, reduced durability, and ultimately a shorter lifespan for the road.

Other options do not accurately reflect the impact of omitting anti-stripping agents. For example, the mix will not cure faster without those agents, and the final product will not necessarily have a smoother surface or become more elastic. Instead, without the proper additives, the integrity of the asphalt-aggregate bond is compromised, which is crucial for maintaining the quality and longevity of the pavement.
