- Remote Locations: In remote areas where access to larger asphalt plants is limited, a mini asphalt plant can be a convenient solution to produce asphalt on-site.
- Quick Repairs: Mini asphalt plants are handy for quick repairs or patchwork on roads, highways, or infrastructure where a small amount of fresh asphalt is needed promptly.
- Cost-Effective Production: If you have a small budget or need to control costs, a mini asphalt plant can be a cost-effective option for producing asphalt in smaller quantities without compromising on quality.
- Testing and Research: Mini asphalt plants are also used for research and testing purposes in laboratories, educational institutions, or for experimenting with different asphalt mixtures.
How Is The Return On Investment In Asphalt Plants?
The return on investment (ROI) in an asphalt plant can vary depending on several factors, including the initial investment cost, production capacity, market demand, operating costs, and efficiency of the plant.
The purchase of asphalt mixing plant actually only accounts for less than 2% of the entire investment. The procurement cost of aggregates and bitumen accounts for more than 75% of the total cost, followed by fuel, which accounts for about 12%.
In other words, a set of asphalt mixing plant can bring unexpected return on investment by reducing the cost of fuel and raw materials while ensuring the output and quality of final asphalt mixture.

- Follow the specific start-up sequence outlined in the plant’s manual, which may include activating the heating system, burner, and conveyor systems.
Material Loading:
- Load the required aggregates into the feeder bins in the correct proportions as per the mix design.
- Ensure that the bitumen tank is filled with the appropriate grade and quantity of bitumen.
Mixing Process:
- Start the mixing process as per the specified parameters. This may involve setting the mixing time, temperature, and drum rotation speed.
- Monitor the mixing process to ensure that the asphalt mixture is blending correctly and uniformly.
Temperature Control:
- Monitor and control the temperature of the aggregates, bitumen, and asphalt mixture throughout the production process.
- Adjust the temperature settings as needed to maintain the desired mix temperature.
Quality Control:
- Regularly sample the asphalt mixture and conduct quality tests to ensure that it meets the specified requirements for temperature, gradation, and asphalt content.
- Make any necessary adjustments to the production process to maintain quality standards.
Storage and Discharge:
- Once the asphalt mixture is ready, transfer it to the storage silo for temporary storage.
- Use the discharge systems to load the asphalt mixture into trucks for transportation to the paving site.
Shutdown Procedure:
- Follow the manufacturer’s guidelines for the proper shutdown of the mini asphalt plant.
- Clean the plant and equipment thoroughly to prevent material buildup and ensure smooth operation during the next use.
Safety Precautions:
- Adhere to all safety guidelines and protocols while operating the mini asphalt plant.
- Ensure that all personnel are trained in safe operating practices and wear appropriate personal protective equipment.
By following these steps and best practices, you can effectively operate a mini asphalt plant to produce high-quality asphalt mixtures for various construction projects. Regular maintenance and adherence to safety procedures are essential to ensure the plant’s optimal performance and longevity.
Hot Asphalt Production Process
The production of asphalt involves a systematic process that combines various raw materials to create a versatile and durable paving material.
Asphalt plants, whether they are mini or standard-sized, typically follow a similar operational framework to produce asphalt. Here’s an overview of how an asphalt plant produces asphalt:
Cold Feed Bins:
The process begins with aggregate materials (such as sand, gravel, and stone) being loaded into separate cold feed bins. Each bin holds a different size or type of aggregate, which is metered out in specific amounts to achieve the desired mix design.
The raw materials used in the production of asphalt typically include:
Aggregates: These are the primary components of asphalt, including crushed stone, gravel, and sand. The type and size of the aggregate used will depend on the desired properties of the final asphalt product.
Asphalt Cement (Bitumen): Also known as tar, bitumen is a sticky, black liquid that is derived from refining petroleum. It serves as the glue that holds the aggregate particles together, providing the asphalt with its strength and durability.
Filler Materials: These are additives that are used to improve the performance of the asphalt. Examples of filler materials include clay, limestone, and silica.
Anchors or Coarse Aggregates: These are larger pieces of aggregate that are used to provide additional strength and stability to the asphalt.
These raw materials are typically heated together in a drum or mixing machine to create the asphalt mixture. The specific proportions of each material used can vary depending on the specific application and desired properties of the asphalt.
Conveyor System:
Aggregates are then conveyed from the cold feed bins to a drum mixer or a drying chamber. Conveyors transport the materials in precise proportions as determined by the asphalt mix recipe.
Drying and Heating:
In the drying chamber, the aggregates are heated and dried using a burner that produces a flame. This process removes moisture from the aggregates and brings them to the appropriate temperature for mixing with asphalt cement (bitumen).
The heating process is carefully monitored to prevent overheating and damage to the aggregate materials.
Mixing with Asphalt Cement:
Hot asphalt cement (bitumen) is stored in insulated tanks and heated to maintain a liquid state. The hot, liquid asphalt cement is then pumped into the mixing chamber where it is blended with the hot, dry aggregates.
The amount of asphalt cement added is carefully measured to ensure the correct proportioning with the aggregates, based on the mix design.
Mixing Process:
The mixing of aggregates and asphalt cement occurs in a mixer or drum, where they are blended together thoroughly to achieve a homogeneous asphalt mixture. The mixing process ensures that each aggregate particle is coated with asphalt cement.
The duration and temperature of the mixing process are crucial parameters that affect the quality of the final asphalt product.
Additional Materials:
In some mix designs, additional materials such as recycled asphalt pavement (RAP), fillers, or additives may be introduced into the mixer to enhance the properties of the asphalt mixture.
Storage of the Finished Asphalt:
Once the mixing process is complete, the finished hot asphalt mixture is discharged from the mixer into a storage silo or directly into trucks. Storage silos keep the asphalt mixture hot until it is ready to be transported to the construction site.
Quality Control:
Throughout the production process, quality control tests are conducted on the asphalt mixture to ensure it meets the specified standards for temperature, consistency, and composition. Adjustments to the process may be made based on test results to maintain quality.
By controlling the proportion of aggregates and asphalt cement, along with the mixing time and temperature, asphalt plants can produce a wide range of asphalt mixtures tailored for various applications, from roads and highways to airport runways and parking lots.
The modern asphalt plant incorporates advanced technology and control systems to streamline the production process and ensure the production of high-quality asphalt.
