Preparation method of sulfur asphalt and mixture
The invention discloses a preparation method of sulfur asphalt and a mixture. The sulfur asphalt is in a water-in-oil type and comprises the following components by weight: 30-97% of matrix asphalt, 0.9-34% of water, 1-6% of emulsifier and 1-30% of sulfur. The preparation method comprises the following steps: the emulsifier is added into the matrix asphalt in a melted state and is uniformly mixed, a certain amount of water is slowly dripped into the matrix asphalt containing the emulsifier and is uniformly mixed, water is dispersed in the asphalt containing the emulsifier in a fine micro-ball state, and then water-in-oil emulsified asphalt is formed; then sulfur is added into the water-in-oil emulsified asphalt and mixed uniformly and has a full reaction with the asphalt to obtain the sulfur emulsified asphalt. The high-temperature stability of the sulfur asphalt is good, the preparation temperature of the sulfur asphalt and the mix temperature of the asphalt mixture are low, the anti-track performance of the mixture is good, volatilization of harmful gas and a thermal aging phenomenon of asphalt are reduced, and the sulfur emulsified asphalt and the preparation method are environment-friendly and save energy.
