Accelerated Creep Testing of Trenchless Liners
Physical ageing of commercial polymers used in trenchless relining of sewer pipes has been investigated. The analysis uses modified effective-time theory (ETT) and time-temperature superposition (TTSP) methods. The data generated by this study show that the time-dependent creep properties of these materials can be modeled within experimental error with changes to the methods reported in the literature. It is shown that a rotation, along with a horizontal shift of the ageing data, is needed to obtain the ageing parameter of the materials. Temperature has no effect on the ageing shift rate. The TTSP is shown to be an accurate method for determining the shift factors to adjust creep data for temperature changes. A novel method is presented to predict the creep behavior of full-scale specimens. The method relies on novel procedures to generate and shift the TTSP master curve from the reference testing age and reference temperature to the testing age and temperature of the full-scale specimens.
