▎ 摘　　要

NOVELTY - Road asphalt comprises petroleum asphalt, compatibilizer, stabilizing agent, antioxidant, flow improver, modified graphene oxide, modified bagasse molecular sieve and styrene butadiene styrene. USE - Used as road asphalt. ADVANTAGE - The road asphalt: has excellent impact effect under the high temperature, high resistant, high stability, more stable structure, excellent high and low temperature resistance performance, is waterproof, ultraviolet, function of flame retardant, and can be normally used for a long time under extreme temperature difference environment. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the road asphalt comprising (i) mixing graphene oxide and modified bagasse molecular sieve, adding 50% compatibilizer, wet grinding, and mixing uniformly, (ii) in a high shear blender, adjusting stirring speed to 4000-6000 revolutions/minutes, heating the petroleum asphalt to 180-220 degrees C, adding remaining amount of 50% compatibilizer, stabilizing agent, antioxidant, flow improvers, and styrene-butadiene-styrene, keeping the temperature and stirring for 15-25 minutes, and (iii) adding the mixture obtained the step (i), continuously stirring for 30-60 minutes to form homogeneous system.
