Product Description
Cold-mixed asphalt mixture is a type of asphalt mixture that is formed by mixing aggregates with emulsified asphalt at room temperature and then allowing it to cure for a certain period of time. Compared with traditional hot-mixed asphalt mixtures, cold-mixed asphalt mixtures have the advantages of convenient construction, low energy consumption, and environmental friendliness. They are widely used in road maintenance, reinforcement, and renovation projects.
Product features
- 1. Convenient construction: Cold-mixed asphalt mixture can be applied at room temperature without the need for heating, reducing energy consumption and lowering construction costs. Moreover, during the construction process, there is no smoke or noise, resulting in a smaller impact on the environment.
- 2. Excellent performance: Cold-mixed asphalt mixture has good adhesion, anti-peeling property and durability, effectively preventing water from penetrating and prolonging the lifespan of the road.
- 3. Strong adaptability: Cold-mixed asphalt mixture is suitable for various climate conditions and different grades of roads. Even in harsh environments such as high temperatures, high humidity, and low temperatures, it still maintains excellent performance.
- 4. Ready Lane： Cold-mixed asphalt mixture has a fast construction speed and short curing time. Generally， it can be opened to traffic within 2-4 hours， significantly reducing the road closure time and improving traffic efficiency.
- 5. Environmental protection and energy saving： During the construction process of cold-mixed asphalt mixture， no heating is required， reducing energy consumption and environmental pollution. At the same time， cold-mixed asphalt mixture can be recycled using waste asphalt pavement materials， saving resources and reducing project costs.
Product application scope
The cold-mixed asphalt mixture is mainly applied in the following aspects:
- Road maintenance:such as the repair of potholes, cracks, looseness and other damages, as well as the functional restoration of road surfaces.
- Road reinforcement: such as thin-layer reinforcement, local thickening, etc., to enhance the road's load-bearing capacity and service life.
- Road renovation: such as the construction of special functional road surfaces like road markings, colored road surfaces, and anti-slip road surfaces.
- New road construction: such as the construction of low-speed roads, urban roads, sidewalks, etc.
Construction Process
1. Material Preparation: Select appropriate aggregates and emulsified asphalt, and mix them in accordance with the design requirements.
2. Mixing: Add the aggregates and emulsified asphalt to the mixer in the prescribed proportion and mix them thoroughly.
3. Compaction: Pour the mixed cold-mixed asphalt mixture into the compaction machine and spread it at the specified thickness.
4. Compaction: Use a roller to compact the spread cold-mixed asphalt mixture until it reaches the required density as per the design specifications.
5. Maintenance: After the surface of the compacted cold-mixed asphalt mixture dries, maintenance should be carried out. The general maintenance period is 2 to 4 hours.
6. Opening: After the maintenance period is over, inspections should be conducted to confirm the qualification. Then, the road can be opened for traffic.
Quality Control of Cold-Mixed Asphalt Materials
1. Strictly control the quality of raw materials to ensure that the mineral aggregates and emulsified asphalt meet the design requirements.
2. Follow the design specifications precisely for the mixing ratio to guarantee the stability of the performance of the cold-mixed asphalt materials.
3. Strengthen on-site management to ensure the standard operation of the mixing, spreading, and compaction processes.
4. Conduct tests on the completed cold-mixed asphalt materials, including indicators such as density, thickness, and flatness, to ensure the quality of the project.
Conclusion
Cold-mixed asphalt mixture, as a new type of environmentally friendly and energy-saving road material, has the advantages of convenient construction, strong adaptability, and ready lane. It is increasingly favored by road builders and users. In the future road construction and maintenance, cold-mixed asphalt mixture will play an increasingly important role.
