Test Method Title

Determination of Adhesion and Bond Strength of Geocomposites **GRI has discontinued this method, the industry-accepted standard test method is now ASTM D7005

Reference Number

GRI GC 7

Material

Geocomposite, Geocomposite

Test Property

ply adhesion, peel strength, bond strength

Description of Test

The geotextile is carefully separated from its associated material and then the two ends are placed in the grips of a tensile testing machine and pulled in a peel-type manner. The average force (adhesion) and force per unit width (bond strength) to separate the layers is reported.

Number of Test Specimens

5 machine direction

Test Specimen Size

2" x 8"

Keywords

adhesion, bond, ply
