Civil Engineering Materials Testing

What is Civil Engineering Materials Testing?

Civil engineering materials testing provides testing, consulting, and research services for geosynthetics and civil engineering materials (such as aggregates, asphalt concrete, ready-mixed concrete, steel products, and mesh types) used domestically and internationally. The program also operates a GAI-accredited laboratory and conducts reliability assessments for geosynthetics.

Test Items

  • Geosynthetic Testing

    • Testing is performed on drainage materials (PBD, PHD), mats (PP, PET, composite fabrics), nonwoven fabrics, geogrids, and more.
Target Main Test Items Representative Standard
