▎ 摘 要
NOVELTY - Graphene oxide modified chromatic asphalt cementing material comprises 0.3-5 wt.% graphene oxide and 95-99.7 wt.% colored asphalt cementing material. USE - Used as graphene oxide modified chromatic asphalt cementing material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing graphene oxide modified chromatic asphalt cementing material, comprising (i) taking 0.3-5 wt.% graphene oxide and 95-99.7 wt.% colored asphalt cementing material, (ii) ultrasonically dispersing graphene oxide using N-methylpyrrolidone to obtain graphene oxide dispersion, (iii) heating the colored asphalt cementing material to 160-185 degrees C, adding graphene oxide, and first stirring swelling at 160-185 degrees C for 1 hour, and (iv) second time stirring for 40-60 minutes until the graphene oxide is uniformly dispersed in the colored asphalt binder to obtain final product.
