Abstract: A pre-processed polymer concentrate in binder comprising a binder and at least one polymer that contains at least 60% conjugated diene where the polymer comprises greater than 26% by weight of the pre-processed polymer concentrate in binder, where the pre-processed polymer concentrate in binder is capable of incorporating quickly into diluent binder under low shear conditions and where the pre-processed polymer concentrate in hinder does not comprise chlorinated polymer.

Abstract: A method for formulating an emulsified polymer modified asphalt, and the emulsion thus created. The method includes mixing at least one polymer and a first binder in a high shear device to produce a polymer-binder composite, where the polymer is at least 70% butadiene; mixing the polymer-binder composite with a second binder to form a polymer modified asphalt; and emulsifying the polymer modified asphalt by combining effective amounts of an emulsifying agent and of water with the polymer modified asphalt. The polymer-binder composite may be produced at lower than room temperature or may include metal fatty acids, such that the resultant polymer-binder composite may be stored and transported at room temperature.

Abstract: A method of making a polymer-binder composite, and the composite thus created. The method employs a high shear device that mixes together polymer with binder, and optionally with additive. The mixing is accomplished in less than one hour, less than 30 minutes or less than 3 minutes, and done at high shear rates. The shear conditions are defined by scalar shear quantity greater than 250, 1,000 or 1,500, resident time of greater than 0.05, 0.10 or 0.20 seconds, and energy utilized per unit mass of greater than 0.05, 0.10 or 0.20 kW/kg. The composite thus produced can be made with a high percentage of polymers. It can be cooled and cut into pellets that are dry and stable at normal temperatures and which can be stored or transported without heating to secondary mixing locations. The composite pellets are quickly soluble in the additional binder.
