1. Introduction to Cold Recycled Asphalt Emulsifier
Cold recycled asphalt emulsifier is a surfactant specifically used for the cold recycling of emulsified asphalt, usually cationic slow cracking and slow setting type. It endows emulsified asphalt with excellent mixing workability through a specially designed formula, enabling complete adhesion to milling materials and providing a longer working time (usually less than 6 hours). The emulsified asphalt produced by cold recycled asphalt emulsifier (LT-M2) has a wide range of compatibility of lotion stone, and the mixture prepared by LT-M2 has a long mixing time and a remarkable feature of slow cracking and slow setting. It has good emulsifying performance and the produced emulsified asphalt has good stability.
2. The role of cold recycled asphalt emulsifier
(1) Improving mixing workability: The specially designed formula enables emulsified asphalt to have excellent mixing workability during the cold recycling process, achieving complete adhesion to the milling material and ensuring the uniformity and stability of the mixture.
(2) Extended working time: Emulsifiers can provide a longer working time, usually less than 6 hours, which helps with operations and adjustments during the construction process.
(3) Rapid formation of early strength: After paving, emulsified asphalt is crushed and demulsified to ensure the rapid formation of early strength of the recycled mixture, meeting the requirement of core sampling 3 days after construction.
3. Usage method of cold recycled asphalt emulsifier
Add the pre measured emulsifier to water, stir and heat up to 60-70 ° C, and heat up the asphalt to 120-130 ° C to start emulsified asphalt production.
4. Scope of application of cold recycled asphalt emulsifier
Permeable oil, slurry seal, cold regeneration
5. Main technical indicators of cold recycled asphalt emulsifier
(1) Appearance: Brown liquid
(2) Active ingredient content: 85 ± 2%
(3) PH value: 8.0-10.0
(4) Dosage: 2.5-3.0%
(5) Packaging: 200kg/drum
6. Application scenarios of cold recycled asphalt emulsifier
Cold recycled asphalt emulsifier is mainly used for factory mixed cold recycling and on-site cold recycling of asphalt pavement, suitable for various grades of highways, municipal roads, and airport runways. Its usage is simple, does not require acid adjustment, and is convenient to use.
7. Comparison with other types of asphalt emulsifiers
The main difference between cold recycled asphalt emulsifiers and other types of asphalt emulsifiers is that they are specifically designed for cold recycling and have the characteristics of slow cracking and slow setting, making them suitable for specific construction conditions and requirements. For example, CLS-C0 emulsifier is a cationic slow cracking and slow setting emulsifier, particularly suitable for cold recycling construction, while other types of emulsifiers may not possess these characteristics.
