Modern asphalt paving systems use multiple components that work together to support traffic, manage moisture, and maintain pavement stability. This article explores the structure of an asphalt pavement system, including subgrade preparation, aggregate base, drainage, asphalt layers, material selection, placement, and compaction. It also explains how pavement design can account for traffic loads, environmental conditions, water infiltration, and expected use. Understanding these components provides valuable insight into why proper pavement design and construction practices are important for achieving consistent performance and extending the functional life of asphalt surfaces.
