Embodiment 1
[0060] A kind of asphalt mixture, refer to figure 1 , the preparation method of asphalt mixture is as follows:
[0061] S1. Add 100kg of asphalt into the stirring tank, heat the asphalt to 170°C, add 3kg of ethanol tellurium, 0.3kg of biphenyl ditellurium, keep the temperature at 170°C, rotate at 60r / min, and stir for 5min to form a premix;
[0062] S2. Add 120kg of fine aggregate to the premix, keep the temperature at 170°C, rotate at 45r / min, and stir for 8min to form a rough mixture.
[0063] S3. Add 180kg of coarse aggregate to the rough mixture, keep stirring at a constant temperature of 170°C and a rotating speed of 40r / min for 10 minutes to form an asphalt mixture.
Embodiment 2
[0065] A kind of asphalt mixture, refer to figure 1 , the preparation method of asphalt mixture is as follows:
[0066] S1. Add 100kg of asphalt into the stirring tank, heat the asphalt to 175°C, add 4kg of ethanol tellurium, 0.4kg of biphenyl ditellurium, keep the temperature at 175°C, rotate at 60r / min, and stir for 5min to form a premix;
[0067] S2. Add 130kg of fine aggregate to the premix, keep the temperature at 175°C, rotate at 45r / min, and stir for 8 minutes to form a rough mixture.
[0068] S3. Add 200kg of coarse aggregate to the rough mixture, keep stirring at a constant temperature of 175°C and a rotating speed of 40r / min for 10 minutes to form an asphalt mixture.
Embodiment 3
[0070] A kind of asphalt mixture, refer to figure 1 , the preparation method of asphalt mixture is as follows:
[0071] S1. Add 100kg of asphalt into the stirring tank, heat the asphalt to 180°C, add 5kg of ethanol tellurium, 0.5kg of biphenyl ditellurium, keep the temperature at 180°C, rotate at 60r / min, and stir for 5min to form a premix;

Abstract
The invention relates to the technical field of asphalt materials. Aiming at the problem of easily forming ruts, an asphalt mixture is provided. The technical solution is as follows: the components include the following parts by mass: 100 parts of asphalt; 120-140 parts of fine aggregate; 180‑220 parts of aggregate; 3‑5 ethanoltellurium; 0.3‑0.5 biphenyl ditellurium. Also provided is a method for preparing an asphalt mixture, comprising the following steps: S1. heating the asphalt to 170°C-180°C, adding telluriumethanol and biphenyl ditellurium, and stirring uniformly to form a premix; S2. in the premix Add fine aggregate and stir evenly to form a coarse mixture; S3. Add coarse aggregate to the coarse mixture and stir evenly to form an asphalt mixture. By adding ethanoltellurium and biphenyl ditellurium to the asphalt mixture, and blending ethanol tellurium, biphenyl ditellurium and asphalt in a specific ratio, the anti-rutting performance of the asphalt mixture can be effectively improved, so that when the asphalt mixture is used to pave the road surface, the road surface It is not easy to deform and rut, which effectively improves the service life and stability of the road surface.
Description
technical field [0001] The invention relates to the technical field of asphalt materials, in particular to an asphalt mixture and a preparation method thereof. Background technique [0002] Asphalt mixture is often used to pave the pavement layer of roads, which are municipal structures used to carry vehicles and pedestrians. [0003] Generally, asphalt pavement is a soft material. When the temperature is high in hot summer, the bearing capacity of the pavement will decrease. Deformation forms ruts, destroys the smoothness of the asphalt surface, and damages the road. Therefore, there is still room for improvement. Contents of the invention [0004] Aiming at the deficiencies in the prior art, the first purpose of the present invention is to provide an asphalt mixture which has the advantage of better anti-rutting effect. [0005] To achieve the above object, the present invention provides the following technical solutions: [0006] An asphalt mixture comprising the fol...
