Rubber Bitumen is Not Just "Mixing", It's "Reacting": How to Solve Segregation & Swelling Issues?
GerryJarlIn the era of green road construction, Asphalt Rubber (AR) has become the gold standard for highways due to its superior crack resistance and noise reduction. However, for many asphalt plant managers, producing qualified rubber bitumen is a nightmare.
Common headaches include:
-
Segregation: Rubber powder floats or sinks, leading to uneven pavement quality.
-
Incomplete Swelling: Improper temperature control prevents the rubber from fully reacting with the bitumen.
-
Clogging: High-viscosity rubber bitumen easily blocks pumps and pipes.
At FEITENG, with 15 years of manufacturing experience, we offer a proven engineering solution with our DXL Series Rubber Bitumen Plant.
1. Core Tech: Powerful Agitation Prevents Segregation
Rubber powder is light and tends to float. Standard mixers cannot keep it uniformly dispersed. The Feiteng DXL Series is equipped with Frequency Conversion Agitators.
-
Double-Layer Paddles: The upper blades push down while the lower blades lift up, creating intense turbulence.
-
No Dead Zones: This ensures the rubber powder is always suspended and reacting, completely solving the segregation problem.
2. Thermodynamics: Dual Heating System
Rubber bitumen production often requires high temperatures of 180°C - 190°C. Relying solely on thermal oil is often too slow. According to our technical specs, the DXL-28/35 Series features a "Direct Fire + Thermal Oil" Dual Heating System:
-
Fast Heating: A Riello diesel burner heats the fire tube directly to quickly raise the bitumen to reaction temperature.
-
Stable Curing: Thermal oil coils provide gentle heat maintenance to keep the temperature constant for curing, preventing bitumen aging. This combination ensures both production efficiency and material quality.
3. All-in-One: From Production to Storage
Traditional rubber bitumen lines are bulky. Feiteng has integrated the process into a Containerized Unit.
-
Production: High-shear colloid mills (optional) grind and disperse the rubber powder.
-
Development (Curing): Through internal circulation pumps and agitators, the rubber powder fully absorbs the oils in the bitumen, swelling and improving performance.
-
Pumping: Equipped with high-viscosity bitumen pumps to easily transfer the finished product.
4. Eco-Friendly & Cost-Effective
Investing in a rubber bitumen plant is investing in the future. Using recycled tire powder not only meets environmental standards but also significantly reduces material costs compared to finished modified bitumen. Plus, Feiteng’s compact 2.25m width design allows the unit to fit into standard shipping containers, saving you thousands in ocean freight.
