Asphalt Drum Mix Plant
What is an Asphalt Drum Mix Plant?
An Asphalt Drum Mix Plant is a continuous-type mixing plant designed for the mass production of hot mix asphalt (HMA) used in road construction and maintenance projects. This plant mixes aggregates, bitumen (asphalt), and filler material in a single, uninterrupted process inside a rotating drum.
Unlike batch mix plants, a drum mix plant ensures highproduction efficiency, low operating cost, and consistent mix quality, making it ideal for large-scale infrastructure projects like highways, expressways, airports, and urban roads.

Top 10 FAQs on Asphalt Drum Mix Plant
- Q: What is the primary function of an Asphalt Drum Mix Plant?
A: To produce hot mix asphalt for road construction by continuously mixing aggregate, filler, and bitumen. - Q: How is a drum mix plant different from a batch mix plant?
A: Drum mix plants operate continuously, while batch mix plants produce in discrete batches, offering more control but at lower speed. - Q: What are the typical capacities available?
A: From 20 TPH (tons per hour) to 150+ TPH depending on model and requirement. - Q: Is it suitable for remote or hilly terrain projects?
A: Yes, mobile units are available that are ideal for remote and temporary road projects. - Q: What kind of fuel does it use?
A: Diesel, Light Diesel Oil (LDO), Furnace Oil (FO), or even natural gas depending on the burner. - Q: Can RAP (Reclaimed Asphalt Pavement) be added?
A: Some advanced models support RAP integration for eco-friendly, cost-efficient paving. - Q: What type of aggregates can be used?
A: Crushed stones, gravel, sand, and mineral fillers are commonly used. - Q: Is pollution control handled in the plant?
A: Yes, most plants include bag filters or wet scrubbers to reduce dust and emissions. - Q: How is temperature controlled?
A: Via thermocouples and digital temperature controllers within the control panel. - Q: Is it operated manually or automatically?
A: Modern plants are fully automated with user-friendly HMI/PLC-based control panels.
Applications of Asphalt Drum Mix Plant

Used in laying heavy-load industrial driveways and service roads. - National Highway Projects (NHAI)
Large-capacity plants are preferred for national infrastructure development.
Working Principle of Asphalt Drum Mix Plant
- Cold Aggregate Feeding – Different sizes of aggregates are proportionately fed through separate feeder bins with variable speed drives.
- Drying & Heating – Aggregates are conveyed to a rotating drum, where they are dried and heated using a multi-fuel burner.
- Mixing with Bitumen & Filler – Hot aggregates mix with bitumen and filler in the drum, creating hot mix asphalt.
- Discharge – The final asphalt mix is discharged into storage silos or loaded directly into tippers/trucks.
- Control System – A centralized control panel ensures automated monitoring of feed rates, temperature, and overall performance.
Optional Features & Customization
- Mobile trailer-mounted unit
- RAP feeding system
- Wet dust scrubber or bag house filter
- SCADA-based remote control system
- Bitumen tank with thermic fluid heater
- Cold & hot mix storage silos
- Fiber and modifier dosing units (for modified asphalt)
