Installing asphalt pavement from the ground up involves several processes. First, the area to be paved needs to be fully cleared and the soil compacted. Next, a specially mixed gravel aggregate base layer is applied, compacted for stability, and graded for drainage. Finally, hot asphalt is specially mixed for the conditions on the site and poured over the base layer.

The classic field demonstration of this dependency was the Zaca–Wigmore experimental road test conducted in California in the 1950s (2). In this field test, construction variables were held constant and asphalt source was intentionally varied.
