AbstractRepeated foot traffic over conventional roof surfaces was simulated by subjecting different roofing assemblies to cyclic compression testing. A haver-sine compression loading function with a magnitude of and a frequency of 1 Hz was used. Three different plastic foam insulation samples (polyisocyanurate, phenolic and expanded polystyrene) were tested with the loading head (the heel of a work boot) positioned at different angles (15° and 30°). A few common roof configurations (insulation covered with a reinforced PVC membrane, with a modified bituminous membrane, and with a reinforced PVC membrane on top of wood fibreboard) were studied to examine the protective effect of the membranes on the insulation samples against foot traffic.
