UT Arlington civil engineers using recycled plastic pins to shore up failing highway slopes

Landfill material used to mend soilA UT Arlington civil engineering researcher has won a $1 million state transportation department grant to install pins made from reclaimed and recycled plastic along some of the region’s busiest highways to shore up clay soils that support the roads. Sahadat Hossain, an associate professor of civil engineering , demonstrated the technique as a cost effective and efficient solution to failing soil slopes as part of the project during the last few years. His team first installed the pins along U.S. 287 in Midlothian. The study
