CUIRE Laboratory Receives a 330-kip Actuator

In February, CUIRE purchased a 330-kip actuator from MTS Company for its soil box testing of underground pipes. This actuator will be used for the NCHRP SAPL Project to develop structural design methodology for Spray Applied Pipe Liners (SAPLs) in gravity stormwater conveyance conduits through actual size soil box testing. 

This project is led by the Ohio Department of Transportation (DOT) with participation of six other state DOTs (Delaware, Florida, Minnesota, New York, North Carolina and Pennsylvania). After completion of testing, a set of design equations for both rigid (cementitious and geopolymer) and flexible (polyurethane and polyurea) will be developed. Additionally, the CUIRE team will prepare SAPL performance specifications.

For more information on participation in this important project, please call CUIRE at (817) 272-9177 or email CUIRE@UTA.EDU.
