Test of Strength - Pipeline rehabilitation passes strain gauge testing after seven years of service
BY ANGUS W. STOCKING
In March 2010, an unusually configured culvert passing under Florida State Route 16 was rehabilitated with a solution called CentriPipe, utilizing PL-8000 fine aggregate composite concrete developed by AP/M Permaform. Florida Department of Transportation (FDOT) has been monitoring the project closely, with the structural integrity of the rehabilitation of particular interest. PL-8000, whether applied with CentriPipe SpinCaster or in special cases such as the SR 16 project, sprayed onto the internal walls of failing structures, is engineered to provide a structurally sound pipe or culvert, independent of the failing substrate.
