Asphalt warm mix agent is a chemical additive used to reduce the construction temperature of asphalt mixtures. Its main function is to reduce the temperature requirements during mixing, paving, and compaction processes while maintaining the performance of asphalt, thereby reducing energy consumption and emissions.
1. Main components
Organic additives, such as fatty acid amides, waxes, etc., reduce construction temperature by lowering asphalt viscosity.
Chemical additives, such as surfactants, reduce temperature by altering the interfacial properties between asphalt and aggregates.
Mineral additives, such as zeolite, lower the temperature of the mixture by releasing moisture.
2. Advantages
Environmental Protection: Reduce greenhouse gas and harmful gas emissions.
Energy saving: Reduce the energy consumption required to heat asphalt.
Extended construction season: allowing construction at lower temperatures.
Improving the working environment: reducing the impact of high temperatures on workers.
3. Application
Widely used in road construction, especially in cities and areas with high environmental requirements.
4. Precautions
Dose control: The dosage needs to be adjusted according to specific engineering requirements.
Mixing evenly: Ensure that the additive is thoroughly mixed with the asphalt.
Performance testing: Performance testing is required before construction to ensure compliance with standards.
In summary, asphalt warm mix has achieved the goals of environmental protection, energy conservation, and improving working conditions by reducing construction temperature.
