Warm Mix Asphalt (WMA) Water Injection System

A compact, plug-in module that injects precisely metered water into hot bitumen to create controlled foaming—enabling asphalt production at 20–40°C lower temperatures. Plant owners typically see up to 20% fuel savings, faster compaction, cooler worksites, and annual carbon reductions of ~1,500–2,000 tCO₂ per unit.

Key Benefits

• Cut Fuel Use (~20%): Lower burner demand without sacrificing mix quality.

• Cooler, Safer Operations: Reduced heat exposure for crews and surrounding communities.

• Same or Better Performance: Maintains workability, density, and rutting/fatigue resistance.

• Rapid Payback: Savings on fuel and maintenance often offset the investment quickly.

• ESG-Aligned: Tangible CO₂ reductions that support sustainability goals.

How It Works

The system injects micro-quantities of water into the bitumen line to create a fine foam. This increases binder workability at lower temperatures while maintaining the perfect mix quality as HMA.

Features

• Closed-Loop Control: PLC/HMI with precise flow and temperature logic.

• Retrofit-Friendly: Integrates with any asphalt batch mix plant.

• Compact Footprint: Skid-mounted unit for quick installation and service.

• Safety-First Design: Interlocks, alarms, and automatic shutdown logic.

• Low Maintenance: Industrial pumps, stainless lines, and accessible filtration.

Typical Results

• Temperature Drop: 20–40°C below conventional HMA.

• Fuel Savings: Up to 20% reduction in burner fuel consumption.

• Carbon Impact: ~1,500–2,000 tCO₂ avoided per unit per year
  (≈ taking ~400 cars off the road or planting ~70,000 trees).

*Actual results depend on plant capacity, fuel type, aggregate moisture, and operating practices.

Compatibility & Integration

• Plant Types: Batch plant.

• Control: PLC/HMI; supports common plant signals.

• Utilities: Power (3-phase), process water line, network (optional).

• Install Time: Typically 1–2 days with commissioning.

Support & Services

• Commissioning & Training: On-site/remote options.

• Warranty: Standard coverage with optional extended service plans.

• After-Sales: Spares, calibration, and performance audits by DPC.

Ideal For

• EPCs, contractors, and plant owners pursuing fuel savings, ESG targets, and improved site safety—without changing mix designs or adding chemical additives.

FAQ

• Will WMA affect mix performance?
  No—WMA maintains or improves workability and density at lower temperatures when properly controlled.

• How soon do we see savings?
  Immediately upon deployment; payback depends on plant throughput and fuel price.

• Is it compatible with RAP?
  Yes—cooler mixes often improve workability with RAP; results depend on RAP %, binder, and moisture.
