Problems solved by technology

The strength of pure emulsified asphalt material is low, and the emulsified asphalt surface is sprinkled with gravel with a certain particle size to make it have a certain strength, which is convenient for maintenance workers to walk, but the sprinkled gravel is easy to peel off in the wind, sun and rain, and high-speed The train wind generated when the train passes is easy to blow the loose particles to the line and hit the train, causing safety hazards. At the same time, the pores formed by the gravel are likely to cause aging and brittleness of the cured emulsified asphalt layer
[0008] In view of the above problems, there are no commercially available maintenance materials or the commercially available maintenance materials are prone to aging or cracking due to freezing and cannot meet the requirements of use

Embodiment 1

[0055] Composition and dosage of decolorized asphalt material

[0056]

[0057] Preparation of decolorized bitumen:

[0058] Add palm oil rich in 30% aromatic hydrocarbons into the reactor and heat it to 170°C, then start stirring and slowly and evenly add Cumar12 and Cumar16 high-viscosity resins. During the process of adding high-viscosity resins, keep the heating device of the stirring tank open , maintain this temperature and stir evenly until no particulate matter exists. The state of uniform stirring can be judged by taking a small sample and observing it with the naked eye. After palm oil and high-viscosity resin are stirred evenly, a small amount of second stabilizer KH570 is added to form decolorized asphalt. From the beginning of adding high-viscosity resin to the end of stirring, the whole process should be controlled within 0.7h.

Abstract

The invention relates to an asphalt-based material decolorizing high-viscosity curing emulsion and a preparation method thereof, and the decolorizing and high-viscosity curing emulsion comprises the following components in parts by weight: 40-60 parts of decolorized asphalt, 1-10 parts of a surfactant, 1-10 parts of a first stabilizer, 30-40 parts of water and 1-10 parts of a polymer curing emulsion. The decoloring high-viscosity curing emulsion has the main function of stabilizing a lower rubble layer, the rubble layer is prevented from stripping under the action of long-term natural conditions, the performance and the service life of a whole waterproof layer structure are not affected, and the emulsion has good waterproof performance and can further protect the lower waterproof layer.

Description

technical field [0001] The invention belongs to the technical field of road maintenance and repair, and in particular relates to a decolorized high-viscosity solidified emulsion of asphalt-based materials and a preparation method thereof, and more particularly relates to a decolorized high-viscosity solidified emulsion of asphalt-based materials used for waterproofing of high-speed railway bridge decks and its preparation method. Background technique [0002] With the continuous improvement of railway transportation capacity and train running speed, the reliability and weather resistance of stable long-term use of lines are becoming more and more important. Among the many factors that affect the safety of railway operation, precipitation is one of the important factors that cause the damage of railway bridge structures, and is also one of the important factors that affect the durability, safety and stability of railway lines. Because rainwater or accumulated water enters th...
