Name one factor that affects the quality of asphalt pavement.

The quality of asphalt pavement is significantly influenced by the material temperature during placement. When asphalt is laid down at the correct temperature, it ensures proper compaction and bonding within the layers of the pavement. The ideal temperature range is crucial for the asphalt to be workable; if the mix is too cool, it may not compact adequately, leading to voids and a weaker pavement structure. Conversely, if it is too hot, there is a risk of overheating the asphalt, which can degrade its properties and lead to premature failure.

Maintaining appropriate material temperature during application contributes to enhancing the durability and longevity of the pavement. This is particularly important as the asphalt needs to be in a semi-liquid state to achieve effective compaction and eliminate air pockets. Properly managed temperature also ensures uniformity in the mix, yielding a consistent surface quality.
