How The Base Layer Controls Asphalt Lifespan & Performance

The base layer is the structural foundation of the entire pavement system, and its quality directly determines how long that pavement will last and how well it performs under real-world conditions. It is typically made of crushed stone or aggregate, graded and compacted to create a stable platform. While it is not visible once the project is complete, it supports the entire pavement system and allows the asphalt above it to perform as intended.
