Large-particle-size permeable asphalt mixture based on horizon function and preparation method of large-particle-size permeable asphalt mixture
The invention relates to the field of building materials, and particularly discloses a large-particle-size permeable asphalt mixture based on a horizon function and a preparation method of the large-particle-size permeable asphalt mixture. The large-particle-size permeable asphalt mixture based on the horizon function comprises the following raw materials in parts by weight: 50-60 parts of petroleum asphalt, 75-80 parts of coarse aggregate, 3-5 parts of mineral powder, 5-7 parts of modified polysiloxane and 1-3 parts of a stabilizer, the stabilizer is prepared by mixing a coupling agent, an initiator and a cross-linking agent, and the mixing mass ratio of the initiator, an activating agent and the coupling agent is 1: (0.5-0.8): (1-1.2); the modified polysiloxane is aryl modified polysiloxane; the preparation method comprises the following steps: heating the petroleum asphalt to 180-190 DEG C, adding the modified polysiloxane, stirring and mixing at a high speed, adding the coarse aggregate, the mineral powder and the stabilizer, and uniformly stirring to obtain the large-particle-size permeable asphalt mixture based on the horizon function. The composition disclosed by the invention can be used for occasions needing water permeability and water resistance, such as road construction, parking lots and squares, and has the advantages of good water permeability and high durability.
