Assessment of Creep Reduction Factors of High-Density Polyethylene Geogrids Using Conventional and Stepped Isothermal Methods
Original research · free full-paper access · authors credited
Research overview
Conventional and stepped-isothermal creep tests on HDPE geogrid compare 100-year creep-reduction factors derived from 20% strain and rupture criteria. The reported factors varied from 2.30 to 3.04, and accelerated results diverged from conventional tests beyond about 1,000 hours; the single tested material, thermal sensitivity, extrapolation and criterion choice limit direct adoption in design.
