Modified Bitumen Equipment

Modified Bitumen Equipment Overview

Modified bitumen, enhanced with polymers like APP or SBS, requires specialized equipment for production, application, and quality control. Below is a categorized list of essential equipment:

​

  • 1. Production Equipment

    • ​High-Shear Mixers/Reactors: Used to uniformly disperse polymers (e.g., SBS) into bitumen under controlled temperatures.
    • ​Storage Tanks: Store raw bitumen and modifiers (polymers, additives) before processing.
    • ​Heating Systems: Maintain optimal temperatures (typically 150–200°C) during mixing to ensure proper viscosity.
    • ​Pumps and Transfer Systems: Move viscous bitumen through production lines (e.g., gear pumps, screw conveyors).
    • ​Environmental Controls: Fume extraction systems, scrubbers, and filters to manage emissions.

  • 2. Application Equipment

    • ​Torches/Hot-Air Welders: Melt modified bitumen membranes for seamless adhesion.
    • ​Mechanical Spreaders/Rollers: Apply and compact membranes evenly.
    • ​Cold Adhesive Sprayers: For solvent-free application in colder conditions.
    • ​Asphalt Mixers: Combine modified bitumen with aggregates.
    • ​Pavers and Compactors: Lay and compress asphalt for roads.
    • ​Temperature-Controlled Silos: Store hot mix asphalt before application.
