NOVELTY - Water-soluble graphene modified colorful emulsified asphalt comprises 0.1-1 wt.% water-soluble graphene, 1.5-3 wt.% cationic emulsifier, 60-65 wt.% chromatic asphalt cementing material and deionized water (balance amount). USE - Used as water-soluble graphene modified colorful emulsified asphalt. ADVANTAGE - The asphalt solves polymer as modifying agent has no significant effect on the performance improvement of the emulsified asphalt. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing water-soluble graphene modified colorful emulsified asphalt comprising (i) heating the deionized water to 60-70 degrees C, then adding acidic agent, and adjusting pH value of aqueous solution to 2.5-3, (ii) adding weighed soluble graphene added into the aqueous solution, and then adjusting pH value of aqueous solution using acidic agent to 2.5-3, and (iii) heating chromatic asphalt cementing material to 150-165 degrees C, adding obtained solution and high speed stirring to obtain final product.
