A method for manufacturing modified asphalt is characterized by adding a dispersion agent such as furfural or vegetable oil to a modifier material and then mixing the modifier material with asphalt. The dispersion agent facilitates dispersion of the modifier through the asphalt to form a homogeneous mixture. A first activator is added to the mixture to produce a devulcanized and stabilized asphalt material having improved rheological, separation and solubility characteristics. A micro activator is also added to the mixture to improve the ductility of the modified asphalt. The modifier material comprises granular crumb rubber or polymer. <IMAGE>
