This paper presents the behavior of strength at yield and secant modulus of HDPE Geomembrane, which is recently well known for landfill, at different temperature conditions. The equations belows are obtained from the test results.
qy=240-2.79t qy: strength at yield, t: temperature
E=8180·10-0.0125t E: secant modulus at 1%
These mean that the relation between strength and temperature is linear, but the relation between secant modulus and temperature is exponent. The most important point for designing or application is that HDPE geomembrane has extremly high modulus at low temperature. And the induced load of HDPE geomembrane at cooling condition is measured and compared with the value obtained from coefficient of expansion and secant modulus at different temperature.
