Abstract:The author describes in detail, complete with diagrams and test data, the procedures adopted and results obtained. The main problem involving the elongation of the membranes is the large difference between the elongation of the polyester-fibre-based modified bituminous membranes, and the elongation of the glass-fibre-based oxidized bitumen membranes.
Keywords:tensile strength  longation  toughness  strain energy  natural weathering  artificial weathering  roofing systems  degradation
