NOVELTY - Bacteriostatic modified asphalt comprises 80-100 pts. wt. pretreated asphalt, 10-20 pts. wt. epoxy resin and 10-15 pts. wt. modified graphene. USE - Used as bacteriostatic modified asphalt. ADVANTAGE - The bacteriostatic modified asphalt: has good bacteriostatic performance, good low-temperature crack resistance and good high-temperature resistance. DETAILED DESCRIPTION - AN INDEPENDENT CLAIM is also included for preparing bacteriostatic modified asphalt comprising (1) mixing asphalt with maleic anhydride, stirring and reacting to obtain pretreated asphalt, (2) mixing pretreated graphene with zinc nitrate hexahydrate, after stirring the reaction, filtering to obtain a filter cake, and mixing the filter cake with 2-methylimidazole in an organic solvent, adding zinc nitrate hexahydrate and modified titanium dioxide, after stirring the reaction to obtain modified graphene blank, mixing the modified graphene blank with the reducing agent solution, stirring and reacting, filtering, and drying to obtain modified graphene, (3) mixing the epoxy resin with the modified graphene, adding pretreated asphalt and after stirring and reaction to obtain bacteriostatic modified asphalt and (4) performing index analysis on the bacteriostatic modified asphalt.
