Feb 01, 2011 A common observation frequently mentioned in the literature [1] is that foamed asphalt, when injected onto agitated granular materials, tends to bond the finer aggregate particles to form the asphalt mastic phase, which exists in the form of numerous small droplets in loose foamed asphalt mixes.

Foams with higher expansion ratios and longer half-life have better dispersion through granular materials, resulting in greater strength improvement. High fines contents in the PAP materials negatively affect mix strength by producing a continuous and weak unbonded mineral filler phase.

Granular materials are commonly used as base or sub-base layers in a variety of construction applications, specifically as support for both asphalt and concrete pavement. Using granular materials as a base will provide pavement with added stability, allow for improved drainage, and help protect the surface from the worst effects of frost.
