Reference Number

GRI GS 1

Material

Geocomposite, Geotextile

Test Property

CBR puncture strength

Description of Test

A force is exerted against the center of the unsupported portion of the test specimen by a steel plunger attached to the load indicator until rupture occurs. The maximum force is the value of puncture strength.
