**2.2. Short-term compressive test**

Short-term compressive deformation testing was performed in accordance with ASTM Standard Test Method (ASTM D6364-06; Standard Test Method for Determining Short-Term Compression Behavior of Geosynthetics) [10].

The geonet specimens were placed between two steel sheets and compressed at a strain rate of 1.0 mm/min. The compressive strength was measured while varying the strain. The compressive strength of the geonet is determined by parameters such as thickness, mass per unit area, crystallinity, strand strength, bonding strength of strand, strand angle and inclination in plane, test conditions are 23, 35 and 50°C, Strain rates were 0.1, 0.5, 1.0, 5.0 and 10mm/min. **Figure 2** shows the test pattern according to various parameters.-
