THE MORPHOLOGY OF POLYMER MODIFIED ASPHALT AND

Polymer modified binders are typically used for PFC mixtures. Sometimes the polymer modifier does little to enhance the ductility of the unmodified binder. The best method to understand what causes this lack of ductility improvement is microscopy which allows the polymer’s microscopic two phase system to be viewed in the asphalt binder.
