Abstract EN
In order to explore the construction performance of zeolite asphalt mixture, the microproperties of zeolite and the macroproperties of zeolite asphalt mixture were studied.
The structure composition, surface properties, and pore characteristics of zeolite were analyzed by infrared spectroscopy and pressure pump method.
The structure, composition, and thermal stability of zeolite were analyzed by differential scanning calorimetry and thermogravimetry, the mechanism of moisture absorption and loss of water was explored, and the properties of moisture absorption and loss of water were studied.
The effect of the type and amount of zeolite on the viscosity of asphalt was studied by the viscosity test.
According to the mixing current and the compaction void ratio, the influence of zeolite on the construction performance of zeolite asphalt mixture was studied.
The results show that zeolite contains special zeolite water and the pore content of zeolite is much higher than that of mineral powder.
Zeolite loses water at 90°C∼120°C, which is the necessary condition for zeolite to be used in warm mix asphalt mixture.
The water absorption and loss capacity of zeolite mainly depend on pore volume.
The larger the pore volume is, the stronger the water holding capacity of zeolite is.
Meanwhile, the water holding capacity and loss capacity of zeolite are related to pore size distribution.
According to the viscosity temperature equation, the mixing and compaction temperature of the asphalt mixture are determined.
The mixing and initial pressure temperature of the zeolite asphalt mixture are lower than those of the hot asphalt mixture.
Based on the principle of mixing current equivalence, the mixing temperature of zeolite asphalt mixture can be reduced by 20°C compared with that of hot asphalt mixture.
The better the water loss performance of zeolite is, the easier the mixture is to be compacted.
For the base asphalt mixture, the compaction temperature of the mixture is 120–130°C, and, for the modified asphalt mixture, the compaction temperature is 130–140°C.
