▎ 摘　　要

NOVELTY - Modified asphalt mortar comprises 15-20 wt.% nano melamine oligomer modified emulsified asphalt, 2-8 wt.% cement, 5-25 wt.% phosphogypsum, 20-45 wt.% blast furnace slag, 10-20 wt.% river sand, 1-3 wt.% anhydride, 2-4 wt.% maleic anhydride graft modified polyethylene ether, 0.4-1 wt.% nano diatomite, and water; where nano melamine oligomer modified emulsified asphalt comprises 30-60 wt.% asphalt, 8-15 wt.% melamine oligomer, 0.8-1.4 wt.% nano graphene, 0.3-0.9 wt.% nano diatomite, 0.5-3.5 wt.% emulsifying agent, 0.1-0.3 wt.% stabilizing agent, 0.2-0.4 wt.% W2 stabilizing agent, 0-0.15 wt.% pH auxiliary agent, 0.5-2 wt.% alcohol, 0.2-2 wt.% dispersant, and water. USE - Modified asphalt mortar is used for building cement concrete road surface, water stabilizing base layer road surface and bridge surface. Can also be used as adhesive and waterproof structure. ADVANTAGE - The modified asphalt mortar has less hardening shrinkage, small rigidity, large deformation ability, especially freeway cement concrete bridge surface and water-stable base layer paving structure, it can effectively solve the problem of bridge layer bonding, sealing water and anti-cracking, better for the bridge surface, road surface, ground, anti-corrosion, bonding and so on. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for the preparation method of modified asphalt mortar.
