What is the primary purpose of asphalt in construction projects?

The primary purpose of asphalt in construction projects is to provide a durable and weather-resistant surface for roads and pavements. Asphalt is valued for its ability to withstand harsh environmental conditions, such as heavy rain, snow, and varying temperatures, which can erode other materials. Its flexibility allows it to accommodate the natural expansion and contraction that occurs with temperature changes, reducing the likelihood of cracking and degradation over time. This durability is essential for ensuring that roadways can support heavy traffic loads and maintain a safe driving surface, ultimately leading to longer-lasting infrastructure. While other factors, such as aesthetics and cost, play a role in construction, the main function of asphalt is its structural integrity and resilience in roadway applications.
