Abstract:

Many analytical methods are available within the family of thermoanalytical techniques for characterizing roof membrane materials. These techniques include classical methods, such as differential scanning calorimetry (DSC), differential thermal analysis (DTA), and thermogravimetry (TG), and modern methods, such as thermomechanical analysis (TMA), torison pendulum analysis (TPA), and dynamic mechanical analysis (DMA). This paper summarizes the work of the RILEM/CIB Joint Committee on Membrane Roofing Systems - Thermal Analysis Task Group on TG and DMA Testing of Roofing Membrane Materials. The recommendations from the committee on how TG and DMA can be used to study new and in-service bituminous-and polymer-based roof membrane materials are presented.
