Arrêtez d'acheter du bitume modifié SBS prémélangé : le guide ultime de la production sur site

If you are running an Asphalt Batching Plant for a major highway project, you already know the high cost of Bitume modifié par polymères (PMB), specifically SBS (Styrene-Butadiene-Styrene) modified asphalt.

Many contractors choose to buy pre-mixed PMB from large refineries and transport it to the job site. However, this creates three massive problems:

1. High Material Cost: You are paying a premium markup for the refinery’s mixing process.

2. Polymer Separation (Segregation): During long-distance transport, SBS polymers tend to separate from the base bitumen.

3. Thermal Degradation: Keeping PMB at high temperatures for days during transit degrades the elasticity of the polymer.

The most profitable and reliable solution for modern contractors is On-Site Modification. At BitumenMachine.com, we engineer the exact equipment you need to bring factory-level production directly to your job site: The Feiteng GLS-15 Skid-Mounted Modified Bitumen Plant.

What is the Feiteng GLS-15 Skid-Mounted Plant?

The GLS-15 is not a static factory installation. It is a highly integrated, skid-mounted (mobile) unit designed specifically for field production.

• 100% Transportable: The entire unit is built on a heavy-duty steel skid. It can be easily loaded onto a standard flatbed trailer and relocated as your highway project advances.

• Direct Integration: It connects directly to your existing Asphalt Mixing Plant (AMP). You produce the PMB, and it goes straight into the asphalt mixer—no long-term storage required, ensuring the highest material quality.

The Core Technology: High-Speed Shearing vs. Simple Mixing

You cannot make PMB by simply dumping SBS pellets into a tank of hot bitumen and stirring it. SBS requires extreme mechanical force to dissolve properly.

Based on Feiteng’s engineering blueprints, the GLS-15 utilizes a specialized High-Speed Shear Mill.

• Physical & Chemical Dispersion: The mill operates at incredibly high speeds, forcing the base bitumen, SBS particles, and chemical additives through a precision stator/rotor gap.

• Le résultat : The mechanical shearing and grinding action breaks the SBS down to microscopic levels ($ ≤ 5 µm$), forcing the modifier to blend both physically and chemically with the base bitumen. This guarantees a stable, high-performance binder that resists rutting and cracking.

Engineered for Thermal Efficiency and Zero Segregation

Producing modified bitumen requires precise temperature control and constant agitation during the “curing” (swelling) phase. The GLS-15 is equipped with a built-in 35m³ Curing and Storage Tank designed to handle this flawlessly.

According to our technical specs, the tank features:

• Double-Layer Paddle Mixers: Équipé de 3 sets of 5.5 kW vertical agitators. These powerful mixers create a strong vertical flow, ensuring the SBS polymer never floats to the top or sinks to the bottom.

• Massive Heat Exchange: Powered by an external thermal oil boiler, the tank contains approximately 170 meters of seamless steel thermal oil coils (Φ57 × 3.5 mm). This provides an immense 30㎡ heat exchange area, raising the bitumen to the required reaction temperature rapidly and safely.

Why Switch to On-Site Production?

By upgrading to the Feiteng GLS-15 Unit, you take full control of your supply chain.

• Increase Profit Margins: Buy cheaper base bitumen and SBS pellets instead of expensive pre-mixed PMB.

• Guarantee Quality: Freshly sheared PMB performs significantly better in road tests than PMB that has been sitting in a transport truck for 48 hours.

• Flexibility: Easily adjust your polymer recipe on the fly to meet changing weather conditions or paving specifications.
