ACCELERATED POLISHING MACHINE AZA0984
The AZA0984 Accelerated Polishing Machine is a laboratory-grade apparatus designed to determine the Polished Stone Value (PSV) of aggregates. It simulates real-life tyre-induced wear on road surfacing materials to evaluate skid resistance and surface friction performance. This machine is widely used in highway engineering laboratories, research institutions, and quality control departments.
Manufactured for long-term reliability, the AZA0984 complies with ASTM D3319 and BS 812 (Part 114) standards.
Key Features
- Tests polished stone value (PSV) of road aggregates
- Conforms to ASTM D3319 and BS 812 Part 114
- Heavy-duty rotating disc with abrasive feed system
- Integrated water spray system to simulate wet road conditions
- Powder-coated steel body for corrosion resistance
Description
Purpose & Importance
The polishing of aggregates directly affects road surface friction. Aggregates with low PSV become smooth quickly, increasing the risk of skidding and accidents, especially on highways, curves, and wet surfaces.
The AZA0984 helps engineers select safer, high-friction aggregates before construction.
Working Principle
Aggregate specimens are mounted on a rotating disc. A set of rubber polishing wheels, along with silicon carbide abrasive and a controlled water spray, act on the surface to simulate long-term traffic wear.
After polishing, the samples are tested using a skid resistance tester to determine their PSV.
Applications
-
Highway and expressway material testing
-
Road safety and skid resistance studies
-
Research laboratories and universities
-
Airport runway and bridge projects
-
Government and private QC laboratories
