Description
Technical Field
The invention belongs to the technical field of road building materials, and particularly relates to high-viscosity modified emulsified asphalt and a preparation method thereof.
Background
The emulsified asphalt has wide application in pavement engineering, and particularly in the field of maintenance of asphalt pavements, the emulsified asphalt needs to be modified along with the improvement of the requirement of the pavement engineering on the asphalt performance. The micro-surfacing is used as a pavement maintenance means, can quickly improve the problems of cracks, looseness, rutting, polishing and the like of the pavement, can improve the durability of the pavement, and is widely applied all over the world. The modified emulsified asphalt used as an important cementing material in micro-surfacing has the defects of poor high-temperature performance, insufficient adhesion with aggregate and the like, and further research and study on the modified emulsified asphalt with high viscosity and high softening point are necessary.
The SBR modified emulsified asphalt is used for micro-surfacing and has the problems of insufficient adhesion, poor high-temperature performance, poor track repairing effect and the like; many researchers began to develop research into optimization of the preparation process of SBS modified emulsified asphalt. Currently, the mainstream preparation process of SBS modified emulsified asphalt comprises the following two modes: 1) the conventional method of modifying and emulsifying firstly is suitable for modified asphalt with low SBS mixing amount, but is difficult to meet the maintenance requirement of high-grade pavement; 2) modification and emulsification are carried out simultaneously, and the like thinks that SBS is in a latex form, and the secondary hot mixing method is utilized to prepare SBS modified emulsified asphalt by modifying and emulsifying at the same time, so that the emulsification difficulty of SBS is effectively reduced, the particle size is uniform, the stability is good, and the defects that the solvent selects toluene toxic solvent when preparing SBS latex, thereby limiting the industrial batch production and simultaneously accompanying the defect of low solid content of SBS latex are overcome. In contrast, the related patent CN109721741A makes an improvement by using cyclohexane as a solvent, and can increase the solid content, but because of the production cost, it is not practically popularized and applied; patent CN110804316A discloses a cationic system high solid content SBS modified emulsified asphalt, but its high temperature performance and viscosity still do not meet the requirements of high viscous asphalt. The preparation of the modified emulsified asphalt with high softening point and high viscosity is difficult because the asphalt has high viscosity, high temperature and high requirement on an emulsifier in the emulsifying process.
