Can a 100 t/h asphalt batch plant handle a 30,000 m² city road in Jakarta? I break down tonnage, daily output, site constraints and plant configuration tips to help you decide with confidence.
When customers plan a large city road project in Jakarta, one of the first real questions they ask is simple: “Is a 100 t/h asphalt batch mix plant enough?” I meet many contractors who feel torn between buying a bigger plant for safety and controlling their investment. This article answers that question from real project experience, daily production logic, and practical construction challenges in Jakarta. If you plan a 30,000 m² urban road, this breakdown will help you make a confident and profitable decision.
Before choosing any asphalt mixing plant, I always encourage contractors to translate area into actual asphalt tonnage. This step makes every later decision clearer.
In Jakarta city roads, the common asphalt layer thickness ranges from 5 cm to 10 cm depending on traffic class. For example:
- At 5 cm thickness: 30,000 m² × 0.05 m × 2.35 t/m³ ≈ 3,525 tons of asphalt mixture
- At 8 cm thickness: 30,000 m² × 0.08 m × 2.35 t/m³ ≈ 5,640 tons
Therefore, most urban road projects of this size require about 3,500 to 6,000 tons of asphalt mixture. This realistic number forms the basis of the entire plant selection logic.
After we clarify the total demand, the next natural question is production speed. This is where many customers misunderstand nameplate capacity.
Although the rating shows 100 tons per hour, actual stable output in Jakarta usually reaches 70–90 tons per hour. This difference happens because of:
- High humidity in coastal Jakarta air
- Aggregate moisture after tropical rain
- Traffic delays during material transport
If a plant operates 8 working hours a day:
- Realistic daily output: 560–720 tons
Based on this output, a 30,000 m² city road project usually takes:
- About 6–10 working days for asphalt production
As a result, for normal municipal schedules, a 100 t/h asphalt batch plant can absolutely cover this production requirement.
However, production capacity alone never tells the full story. In Jakarta, real field conditions shape the success of the project.
First, city traffic control limits night paving hours. Second, frequent rainfall shortens effective paving windows. Third, narrow urban streets reduce truck efficiency. Because of these realities, contractors must match plant rhythm with paving rhythm.
A 100 t/h hot mix asphalt plant offers strong advantages here:
- High temperature control stability
- Flexible formula switching for different layers
- Clean and uniform mixture for smoother paving
Therefore, contractors can slow down or speed up production without losing mixture quality. This flexibility matters more than extreme output in dense city projects.
Many project owners worry about choosing “too small” of a plant. However, oversizing brings hidden costs.
For a single 30,000 m² road project:
- A 120–160 t/h plant rarely runs at full load
- Fuel and electricity costs rise significantly - Idle time increases daily operational cost
In contrast, a 100 t/h asphalt batch plant usually works close to its optimal load range. This balance improves fuel efficiency and reduces wear. As a result, contractors gain better profit margins on mid-sized municipal projects.
In short, for this project size, a 100 t/h model often gives the best return on investment.
Capacity is only one part of the story. Real performance depends on technical configuration.
Jakarta’s high rainfall requires strong drying drums. A 100 t/h batch plant with oversized burners and moisture monitoring sensors performs far better than basic designs. This ensures stable output even after heavy rain.
Fuel supply in Indonesia can fluctuate. Multi-fuel burners that can switch between diesel and gas reduce production risk. This feature directly improves project stability.
Modern PLC control allows fast recipe switching. This matters when one project needs base, binder, and surface layers. Accurate weighing reduces material waste and helps contractors control real cost.
Therefore, plant configuration matters as much as rated capacity.
A city road project succeeds only when the plant and site equipment work in harmony.
For a 100 t/h plant in Jakarta:
- One paver typically consumes 200–300 tons per shift
- Two steel rollers and one pneumatic roller complete compaction rhythm
This means one 100 t/h stationary or portable asphalt mixing plant can easily supply one paving team without bottlenecks. At the same time, it avoids excessive truck queuing at the site. This balanced workflow reduces chaos and improves safety.
Even though the 100 t/h plant fits most 30,000 m² city projects, honest planning must consider exceptions.
You may need a larger plant if:
- The schedule requires completion within less than 4–5 paving days - Multiple road sections run simultaneously - Night work windows are very short due to strict city regulations
In these cases, a 120–160 t/h model or dual plant setup makes more sense. Realistic planning always protects profit and reputation.
From my experience, contractors prefer this plant size because it gives a strong balance.
They gain:
- Stable output without oversized investment - Lower fuel and electricity consumption per ton - Easier installation within tight urban or suburban plant yards - Faster permitting because of smaller environmental footprint
These real-world benefits drive long-term satisfaction beyond just technical numbers.
In my daily work, I focus on helping contractors choose equipment that fits actual Indonesian site conditions, not just catalog numbers. I provide practical capacity calculations, layout design support, and local service response. I also help optimize burner systems and dust control solutions for Jakarta’s strict environmental requirements. This approach allows customers to start production faster and operate with confidence.
For most realistic scenarios, the answer is clear. Yes, a well-configured 100 t/h asphalt batch plant can handle a 30,000 m² city road project in Jakarta. It delivers enough output, fits the local working rhythm, and balances investment risk. More importantly, it gives contractors production stability in Jakarta’s complex urban environment.
If you plan a similar project, I can help you calculate the exact production plan and plant configuration. I focus on real performance, real costs, and real site challenges. Once you choose the right plant, your road project becomes faster, smoother, and more profitable. Now is the right time to build smarter and move forward with confidence.
