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.

Polymer modified binder and plant mix modifier for asphalt and process of making

The present invention is directed to a heavy duty pavement structure comprising an open-graded asphalt layer fortified with a non-segregating grout mixture. The heavy duty pavement structure is made through the steps including forming an open-graded asphalt layer and then fortifying the layer with a non-segregating grout mixture that includes a predetermined amount of portland cement, sand and cement binder system.
