Exploring Novel Lightweight Backfills for Geotechnical Structures — NSF Award to University of California-San Diego (CA, $500,000)
This project supports research that looks to build upon concepts from aerospace composites engineering to create new geo-composites that combine geosynthetics and lightweight backfill materials with contrasting stiffnesses (lightweight cellular concrete, LCC and tire derived aggregate, TDA) in different geometric archi

| Abstract | This project supports research that looks to build upon concepts from aerospace composites engineering to create new geo-composites that combine geosynthetics and lightweight backfill materials with contrasting stiffnesses (lightweight cellular concrete, LCC and tire derived aggregate, TDA) in different geometric architectures with characteristics designed to reach desired objectives. Retaining walls have been constructed recently with TDA (a ductile recycled material that has high shear strengt |
