Impact Beads for Road Surface Macrotexture Testing (180-250 µm)

Measurement of macrotexture depth on roads and airfields. Solid, translucent granules at room temperature—odorless—insoluble in water. Standards: EN 13036-1 (Europe) / ASTM E965 (USA) / NF P98 216-1 (France).
Particle size: 180–250 microns. Sphericity: ≥ 80% (round beads). Softening point: approximately 650 °C. Melting point: greater than 1350 °C. True density: 2.5 kg/dm³. Bulk density: approx. 1.5 g/cm³.
Chemically inert, dry, and ready to use. Provides excellent flowability, which is essential for the accuracy of on-site volumetric testing.
