1- CHARACTERISTICS
The Solid Glass Spheres, which are completely spherical and calibrated are clean, dry and prepared in a modern workshop offering every guarantee in terms of quality and consistency.
The Solid Glass Spheres are packaged in :
-
Box of 24 polyethylene bags each containing 1 000 ± 10 g.
-
Lot of 10 pails of 5 kg with handle
-
Lot of 6 pails of 15 kg with handle
Shipments are packed in boxes on pallets of 1 ton maximum.
2- CONTROLS
The grading composition, determined by sieving, complies with the requirements of the norm EN 13036-1 & ASTM E965-96 : at least 90 % of ball mass have a diameter between 0.18 and 0.25 mm.
3- SCOPE
Measurement of average macrotexture depth of a pavement surface using a volumetric technique.
The method may be used on a wide range of surfaces. Nevertheless one should be cautious in interpreting data when the depth measured is outside the interval (0.25 - 5 mm).
Specifications of reception of the solid Glass Spheres in accompanying document.
This grading has been controled by hand, with certified sieves,following control processes created for the CEN standard sand EN 196-1.
