Abstract

The invention relates to high-viscosity modified emulsified asphalt. The high-viscosity modified emulsified asphalt is prepared from the following components in parts by weight: 80-85 parts of matrixasphalt, 1-5 parts of modifier, 0.1-0.5 parts of emulsifier, 0.02-0.05 parts of additive, 0.1-0.2 parts of foamer, 0.1-0.2 parts of defoamer, 0.05-0.1 parts of stabilizer, 10-20 parts of gamma-aminopropyltriethoxysilane and 30-50 parts of water. The high-viscosity modified emulsified asphalt has the beneficial effects that by addition of the gamma-aminopropyltriethoxysilane, the coupling action can make close combination of all components in the asphalt, so that the viscosity of the asphalt is improved; in the preparation process, the foamer is firstly added to foam the modified emulsified asphalt, then the internal structure can be honeycomb-type temporarily, the gamma-aminopropyltriethoxysilane conducts coupling in the modified emulsified asphalt, so that the structure is more three-dimensional, the internal connection is more uniform and denser, after the formed structure is treated by the defoamer, the formed connecting structure is extruded, and the structure is denser, so that the viscosity is greatly increased.
