Abstract
Improved asphalt pavement mixes containing calcium phosphate and processes for producing the improved pavement mixes are provided. The asphalt pavement compositions comprise aggregate, asphalt binder and calcium phosphate. The improved pavement mixes may be produced by blending calcium phosphate with the aggregate prior to combining the aggregate with the asphalt binder. Alternatively, the calcium phosphate may be mixed with the asphalt binder prior to adding the aggregate to the asphalt binder. The addition of calcium phosphate to the asphalt pavement mixtures can improve the stiffness or the moisture resistance of the asphalt pavement mix.
