Test Method Title

Standard Test Method for Measuring Geosynthetic Pullout Resistance in Soil

Reference Number

ASTM D6706

Material

Soil-Geosynthetic Interaction

Test Property

pullout resistance

Description of Test

A geosynthetic material is placed between two layers of soil. A normal load is applied to the setup. The geosynthetic is clamped on one end and pulled out of the soil. The force required to pull the geosynthetic is recorded. Pullout resistance is calculated by dividing the maximum load by the specimen width. A plot of maximum pullout resistance versus applied normal stress is produced when multiple tests are performed at multiple normal loads.

Preferred Test Sample Size
