Belgium PS-I type asphalt pavement depth construction instrument
Product Description
This instrument is used to determine the macro-texture of road surfaces.
The principle is to spread a known volume of dry sand with a specified particle size onto the road surface in a circle of a certain area. The ratio of the sand volume to the average area covered is called the texture depth of the road surface. The unit is millimeters, reflecting the macro-texture of the road surface.

1. Graduated cylinder. Volume: 25 ± 0.15 ml
2. Spreading plate. A 2-4 mm rubber sheet is attached to the bottom.
3. Windbreak.
