Flowability And Density Characteristics Of Controlled Low Strength Material (Clsm) Using Native High Plasticity Clay, Anand J. Puppala, Bhaskar Chittoori, Anil Raavi

Civil Engineering Faculty Publications and Presentations

In pipeline construction projects when high plastic clayey soils are encountered in the excavated trench material, they are typically landfilled and better quality materials are imported from outside quarry sources for use as bedding and haunch zone materials. This practice has detrimental environmental and cost impacts; therefore, an efficient reutilization of this high plastic excavated material to produce controlled low strength materials (CLSMs) to use as bedding and haunch zone materials will have major sustainability benefits. As a part of an on-going research study, novel CLSM mix designs were developed by utilizing native high plastic clayey soils from the excavated …
