Problems solved by technology

After the sticky layer modified emulsified asphalt is sprayed, although the emulsion is completely demulsified and the asphalt is completely condensed after several hours, the sticky layer with wheel marks is still taken away by the asphalt construction vehicles during the paving construction process, resulting in sticky layer effect failure

Abstract

The invention relates to a wheel sticking prevention SBS modified emulsified asphalt used for tack coat. The wheel sticking prevention SBS modified emulsified asphalt is prepared from, by weight, 100-120 parts of asphalt, 1-3 parts of furfural extract oil, 3-5 parts of an SBS high-molecular polymer modifier, 0.3-0.5 parts of a quick-cracking and quick-setting emulsifier, 0.1 parts of an emulsified asphalt stabilizer, 2-5 parts of an organosilicone resin interface reinforcing agent and 100 parts of water. The SBS high-molecular polymer modifier, the quick-cracking and quick-setting emulsifier and the organosilicone resin interface reinforcing agent added to the wheel sticking prevention modified emulsified asphalt commonly improve the pavement performance and the construction performance of the modified emulsified asphalt used for tack coat, make the modified emulsified asphalt be suitable for being used in roads, and can prolong the service life of the roads.

Description

technical field [0001] The invention belongs to the field of industrial chemical industry and relates to a non-stick wheel modified emulsified asphalt. technical background [0002] During the pavement construction process, sufficient vibration and rolling is required when completing the pavement of each structural layer from bottom to top. Therefore, the surface of this structure layer has reached a relatively dense and flat state, and the frictional resistance on the joint surface between layers will be much lower than that of the mixture itself, and its strength composition will become dependent on the cohesive force. If there is no more high-quality material for bonding to create an interlayer body equal to or greater than the strength of the mixture, the interlayer joint surface will become a weak link, which is difficult to withstand the damage of excessive shear force in the horizontal direction. Especially in hot summer, the asphalt pavement will slip between layers...
