The Wehner Schulze method simulates traffic polishing and then measures post-polishing friction so laboratories can quantify aggregate and asphalt surface friction durability under EN 12697-49.
Frequently Asked Questions
What equipment is included in Wehner Schulze Surface Friction Tester for Asphalt?
This section includes LS-ABR-WS and related systems configured for the same workflow family. Buyers usually compare these models by automation level, temperature or load control, reporting workflow, and target standard.
Which standards are common for surface friction after polishing (ws) workflows?
EN 12697-49:2022 are common reference standards for this workflow. Procurement teams often search by these codes first and then compare model capability, control logic, and laboratory throughput.
How do I choose the right surface friction after polishing (ws) system?
Selection usually depends on required standards, automation level, sample throughput, data traceability, and whether the laboratory is focused on daily QC, third-party compliance testing, or advanced research and development.
