Hossain has used recycled plastic pins extensively to repair shallow slopes in TxDOT’s Dallas district.
The pins are about 8-10 feet long and are driven into the slopes to provide stabilization, reducing costs by more than 50% when compared to conventional methods. In addition, the project, led by Sahadat Hossain, who also is director of the Solid Waste Institute for Sustainability, will test the feasibility of stabilizing slopes using just a moisture barrier and no other mechanical support.
