▎ 摘　　要

NOVELTY - A nano modified rare-earth active component-based asphalt pavement maintenance material comprises 10-30 pts. wt. chloroprene acrylic compound latex, 1-3 pts. wt. styrene-butadiene latex, 0.01-0.1 pt. wt. preservative, 1-5 pts. wt. polyvinyl alcohol aqueous solution, 0.5-1.5 pt. wt. defoamer, 0.5-1.5 pt. wt. samarium oxide, 1-1.5 pt. wt. ytterbium oxide, 1-1.5 pt. wt. yttrium oxide, 0.5-1.5 pt. wt. surfactant, 44-54 pts. wt. graphene oxide and 10-30 pts. wt. nano-cerium oxide. USE - Nano modified rare-earth active component-based maintenance material of asphalt pavement in highway and municipal road. ADVANTAGE - The asphalt pavement maintenance material has very high heat insulation effect, and can increase the mechanical abrasion resistance of the asphalt pavement, and prolongs the service life of asphalt pavement. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the asphalt pavement maintenance material.
