The strength of asphalt mixtures is mainly manifested in two aspects. The first is the adhesive force of the cementing material formed by asphalt and mineral powder; the other is the internal friction and the locking force among the aggregate particles. The large surface area of the fine mineral powder particles enables the asphalt material to form a film, so that the bonding strength and the temperature stability of the asphalt material are improved; while the locking forces are mainly generated between the coarse aggregate particles. The asphalt concrete mineral aggregate grade timing is selected and considered, so that the mixture can form a compact and stable pavement with proper roughness and durability after a proper amount of asphalt is added. The asphalt concrete is prepared by hot mixing and cold mixing, and the cold mixing method is easy to fly ash when aggregate is heated and dried, so the hot mixing preparation method is mostly adopted at present. Whether the asphalt raw material and the concrete raw material are thoroughly and uniformly stirred during hot mixing directly influences the quality of the asphalt concrete.
At present, the following defects exist in the existing device for preparing the asphalt concrete: 1. the existing device for preparing asphalt concrete can not heat and emulsify asphalt when the asphalt raw material is put into the device, can not thoroughly and uniformly stir the asphalt raw material and the concrete raw material, and influences the grading ratio of the asphalt and the concrete, thereby influencing the viscosity of the formed asphalt concrete; 2. the device of present preparation asphalt concrete can not be to the timely clearance of striking off of stirred tank inner wall, and the easy adhesion of stirring vane is the pitch that solidifies, leads to using for a long time can accumulate very thick pitch layer, influences asphalt concrete's stirring quality, and stirring mixing efficiency is low, influences asphalt concrete's service quality.
