What is a critical factor in determining the longevity of highway pavement?

The longevity of highway pavement is heavily influenced by the quality of materials and construction methods used. High-quality materials ensure that the pavement can withstand various stresses, such as traffic loads, weather conditions, and environmental factors. Durable materials, combined with effective construction methods, contribute to a well-compacted and well-engineered pavement structure that can resist cracking, distresses, and degradation over time.

Using proper construction techniques is equally important; they ensure that the materials are applied correctly and that the pavement is laid down in a manner that maximizes performance and lifespan. This includes factors such as proper layering of materials, adequate curing times, and effective drainage management. Together, the right combination of high-quality materials and skilled workmanship leads to a more resilient and long-lasting pavement.

While elements like the number of lanes, proximity to urban areas, and even color may have some influence on maintenance and aesthetics, they do not directly impact the inherent durability of the pavement as much as the choice and handling of materials during construction do.
