摘要:
The present invention provides a functionally dry warm mix asphalt binder composition modified with lubricating agents or additives that can be mixed with aggregate and compacted at temperatures substantially below asphalt binder compositions that do not contain the disclosed lubricating additives.
摘要:
Disclosed are asphalt binder compositions that include an anti-aging additive. The anti-aging additive improves various rheological properties. Methods of making such asphalt binder compositions and pavements are disclosed.

摘要:
The present invention provides an asphalt paving composition including an essentially water-free, non-foamed warm mix asphalt binder composition modified with lubricating antistrip additives that can be mixed with uncompacted aggregate to provide a warm mix paving composition of the aggregate adequately coated with the essentially water-free, non-foamed binder and lubricating antistrip additive. This warm mix paving composition may be mixed at temperatures of 280° F. or lower and may be compacted at temperatures of 260° F. or lower that are below mixing and compacting temperatures of similar paving compositions that do not contain the disclosed lubricating antistrip additives.
