What equipment solution is required for the production of bitumen-rubber mastics at an existing asphalt plant?

For producing bitumen-rubber mastics at an asphalt plant the most practical solution is a dedicated bitumen modification unit paired with an inline colloid mill: a USB-3 series modification unit (choice between compact USB-3/12 or higher‑capacity USB-3/16) together with a CLM-8/16 colloid mill. The USB-3 line handles heating, batching, regrinding and high‑shear mixing so you can introduce rubber, polymers, plasticizers or solvents and produce polymer‑modified bitumen and elastomer-containing mastics reliably, while the CLM-8/16 provides the ultrafine inline dispersion and homogenization required for stable bitumen‑rubber mastics and even liquid rubber blends.

These units are designed to be installed at an existing asphalt plant, operate cyclically or continuously, and use thermal‑oil heating for consistent temperature control; training and commissioning are short (typically 1–2 days). For higher throughput the USB-3/16 offers about 16 m3/h capacity; the USB-3/12 is a more compact, transportable option for smaller operations. If you tell me your current plant throughput and available space I can recommend the best SKU mix and configuration to integrate a mastics production line that meets your production and quality targets.
