Application of Emulsified Asphalt in Road Maintenance from quangongzi's blog

This paper describes in detail the application of emulsified asphalt pavement and development, exemplifies the production of the emulsion, the formula of the emulsion, the various spread of the emulsion and the application of the emulsion in the case. Emulsified asphalt, emulsified asphalt is a mixture of two immiscible substances - asphalt and water. The particle size of the emulsion is a relatively important parameter, because the particle size becomes more and more dispersed, the better the viscosity of the emulsion, the better the demulsification rate and the bonding properties. However, this also limits the asphalt content in the emulsion and can affect the curing speed. Under normal circumstances, it is found that VD has the best overall properties when the particle diameter is in the range of 1 to 5 μm. Road Sealing Machine - Road Machinery Equipment Manufacturers - Doan Machinery

The composition and chemical properties of asphalt are complex. With high polarity (polarizing) and higher aromatic asphalt, it is usually easier to emulsify. The use of additives can be used to improve the emulsification effect, in general, high penetration of the asphalt than the low penetration of the asphalt is easy to emulsify. The choice of chemicals in emulsified asphalt depends on the spread of the road. Both the anionic emulsifier and the cationic emulsifier are dependent on the long chain of the hydrocarbons of the salt, which may be the transgenic organisms of the synthetic fatty acids found in the oil A mixture of lignin in fatty acids or wood pulp. General emulsions are controlled by equipment and recipes. The use of a suitable emulsifier, the correct control of the emulsifier effect of the emulsion formula, to produce the need to meet the needs of the emulsion is essential.
