Key Features
4-Station Parallel Rail Architecture
The LS-ABR-1 features a unique linear configuration with four dedicated stations (Polishing, Cleaning, Friction, Calibration) connected by high-precision parallel rails. Specimens slide seamlessly between stages, eliminating handling errors and ensuring sub-millimeter positioning accuracy.
Automated Binder-Film Sandblasting
Equipped with a specialized automatic sandblasting module to strip the initial asphalt binder film from laboratory-compacted specimens. This accelerates the exposure of mineral aggregate micro-texture, providing a more representative simulation of traffic-induced polishing.
High-Precision Torque Friction Mapping
Utilizes an advanced torque measurement assembly and fully automated testing protocols to capture friction values from 0 to 100 km/h. The industrial controller generates real-time performance curves, accurately isolating the impact of mixture design on long-term skid resistance.
Intelligent Thermal & Slurry Management
Features a dedicated quartz-water slurry mixing system and a corrosion-resistant temperature control suite. High-efficiency pumps manage the abrasive delivery, ensuring constant polishing energy in strict accordance with EN 12697-49 standards.
