This invention discloses a heavy-duty durable airport pavement RPC and its preparation method, comprising the following components in parts by weight: 15-30 parts silica fume, 20-50 parts mineral powder, 0-25 parts fly ash, 0-25 parts microspheres, 8-15 parts graphene, 1.5-8 parts composite microsurfactant, 8-25 parts aerosol powder, and 10-15 parts retarding high-efficiency water-reducing agent. The composite microsurfactant includes 1-3 parts sodium glutamate and 0.5-5 parts sodium carboxymethyl cellulose. The heavy-duty durable airport pavement RPC provided by this invention, with solid waste materials as the main body, combined with composite microsurfactants and retarding high-efficiency water-reducing agents, can significantly improve the flexural strength and freeze-thaw resistance of airport pavement concrete when used in concrete, improve the performance of airport pavement concrete, ensure the service life of airport pavement, reduce the amount of maintenance work, and lower construction and maintenance costs.
