POLYMER MODIFIED BINDER AND PLANT MIX MODIFIER FOR ASPHALT AND PROCESS OF MAKING

Title:

POLYMER MODIFIED BINDER AND PLANT MIX MODIFIER FOR ASPHALT AND PROCESS OF MAKING

Document Type and Number:

WIPO Patent Application WO/2011/112569

Kind Code:

A3

Abstract:

The invention provides a polymer modified binder using an asphalt plant mix modifier comprising a mixture of thermoplastic polymers, comprising both elastomers and plastomers, blended with oils and dispersed in a powder medium to facilitate flow. The use of polymers in dry form has provides for a means of incorporating additives into asphalt that can be successfully performed within the normal range of temperatures used for the mixing and compaction of hot mix asphalt.
