This product is a special research project established by the Ministry of Communications and the Highways Department to revise the Technical Specifications for Highway Asphalt Pavement Construction. The products specified in the “Asphalt Pavement Seepage Measurement Method and Index Requirements” are also the standard products in the new test procedures. meets the

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.

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.
