Instructions

:

1

Clean the test piece placed on a solid surface or the road surface to be tested.

2

Put the marker ring, draw the mark along the inner and outer rings with chalk, and remove the mark.

The ring also leaves an inner ring on the surface of the test piece or on the road surface.

Φ150mm

Outer ring

Φ 220mm

Two concentric circles.

3

Place the standard ring in a concentric circle and match the inner ring mark to the bottom of the standard ring

4

Check if the concentric circle has a part with a deeper construction depth, if it is necessary to seal first

The agent fills the texture depth of these parts,

To prevent water from passing through these tables during the water seepage test

The surface texture oozes, which affects the test results.
