Claims25
An asphalt paving composition comprising an asphalt binder and aggregate, wherein the asphalt binder comprises asphalt and a hydrated phosphate modifier.
A modified asphalt binder comprising asphalt and a hydrated phosphate modifier.
A method for reducing the temperature range in which an asphalt paving composition is subjected to a particular compressive force to achieve a particular degree of compaction, the method comprising modifying the asphalt paving composition by adding a hydrated phosphate modifier.
A method for preparing an asphalt paving composition, the method comprising the steps of mixing an asphalt binder, an aggregate, and a hydrated phosphate modifier to produce the asphalt paving composition.
