The project
| Work | Rural, farm-to-market and district roads, 4–6 m wide |
| Mix | One standard asphalt concrete mix for most of the program |
| Daily need | About 250–400 t on paving days |
| Site | One central yard for a year or more |
| Budget | Tight; the agency or contractor wants the lowest cost per ton |
Why a drum mix plant fits
| Need | How the RMX-D60 answers it |
|---|---|
| Low purchase price | No hot elevator, screen, hot bins or pugmill mixer |
| Low running cost | Fewer wear parts; lower installed power (about 105 kW) |
| One standard mix | Continuous production at a steady rate |
| Simple site | Light foundations or trailer-mounted; small footprint |
| Small crew | Simple controls; easy to train |
The trade-off is flexibility: changing recipes is slower, and the mix follows the cold feed closely. That is why stockpile control is part of this solution.
The recommended configuration
| Unit | Specification |
|---|---|
| Plant | RMX-D60, stationary or trailer-mounted |
| Cold feed | Four bins with belt feeders and a weighing belt |
| Drum | Single drum: drying zone, then mixing zone with bitumen and filler addition |
| Dust | Baghouse (recommended near villages) or wet collector |
| Bitumen | One heated tank, about 30 m³ |
| Storage | Finished-mix bin of about 4.5 m³, or a small silo |
| Power | Grid via transformer or a generator sized above 105 kW with margin |
Keeping quality steady
- Separate stockpiles for each aggregate size, on a hard, drained base
- Cover the sand and fines — they hold the most water
- Calibrate the feeders and weighing belt at start-up and regularly after
- Sample every shift for gradation and binder content
- Keep the feed steady — avoid frequent stops and starts
Production planning
| Item | Planning figure |
|---|---|
| Daily output | about 360 t (60 t/h × 8 h × 75%) |
| Road paved per day | about 0.6 km of a 5 m road at 5 cm, or about 1 km at 3 cm |
| Trucks (15–20 t) | 3–5 depending on haul |
| Bitumen per day | about 16–22 t |
Indicative budget
| Item | Indicative figure |
|---|---|
| RMX-D60 plant, FOB China | $75,000 – $110,000 |
| Generator, lab equipment | Quoted per project |
| Freight, duties, installation | Local quotes — see the price guide |
When to choose something else
If the program needs several mixes, or the specification requires batch weighing, look at the RMX-B60 or RMX-M60 batch plants. For help deciding, read when a drum mix plant is enough. Send us your program details.
