"The pipe underwent a stringent and formal testing program required by FDOT, and met all criteria," stated Greg Bohn, director of national engineering at ADS. "Now FDOT contractors, and local agencies whose roadway construction regulations follow FDOT standards, may choose to use polypropylene pipe for their storm drainage applications.
ADS HP pipe provides a superior sanitary-grade joint and can reduce the installed cost versus traditional pipe materials. In addition, the pipe is manufactured with impact modified copolymer polypropylene pipe resins, which provide increased pipe stiffness and excellent durability characteristics to achieve 100-year design service life performance."
To determine the expected service life of ADS HP pipe, FDOT adopted a test protocol specification. Incorporating projected long-term buried stress and environmental conditions, it utilises stress crack resistance and oxidation resistance testing to predict the long-term performance of thermoplastic pipe.
