Abstract
The paper proposes a model for the prediciton of flat roof service life based on the evaluation of the durability of the bituminous waterproofing membrane through accelerated thermal aging tests and its characteristics with Dynamic Mechanical Analysis (carried out with Rheometric RDAI apparatus). Two different quallitites of polymer modified (APP) bituminous waterproofing membranes were tested and these results have been used to measure performance level and to predict service life. DMA tests on waterproofing membranes give information about the material's mechanical behavior that can be related to its molecular structure and can be furthre related to the basic decay process and kinetic reactions relationship. Using the results of accelerated thermal aging test of waterproofing membrane, Service life can be calculated for each flat roof type and climate context.
