Beschreibung
Zusammenfassung: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.
