A test protocol to quantify the peel resistance of adhesive applied low slope roofing specimens subjected to shear loading

This paper documents a segment of the findings from this project. Under the Task 1, investigations were completed by constructing over 600 specimens and examining the peel resistance of bonded roofing components through mechanical separation of bonded layers by applying sheer forces. These specimens were constructed using cold adhesives. Based on this scrutiny, three key parameters, namely: peel position,peel angle, and specimen size were optimized. This paper presents the findings and development of a standardized test method to determine the peel resistance of AARS specimens.Ce document fait \ue9tat d?une partie des conclusions de ce projet. \uc0 la t\ue2che 1, on a compl\ue9t\ue9 les investigations pr\ue9vues en construisant plus de 600 \ue9prouvettes et en examinant la r\ue9sistance au d\ue9collement d?\ue9l\ue9ments de toitures dites garanties (couvertures appliqu\ue9es par adh\ue9sif [CAA]). \uc0 cette fin, on a s\ue9par\ue9 m\ue9caniquement les couches adh\ue9r\ue9es en y appliquant des efforts de cisaillement. Ces \ue9prouvettes ont \ue9t\ue9 fabriqu\ue9es au moyen d?adh\ue9sifs \ue0 froid. \uc0 la lumi\ue8re de ces examens, trois (3) param\ue8tres cl\ue9s ont \ue9t\ue9 optimalis\ue9s, notamment : la position du pelage de s\ue9paration; l?angle du pelage; et la taille de l?\ue9prouvette. Nous pr\ue9sentons les r\ue9sultats de cette enqu\ueate et exposons le d\ue9veloppement d?une m\ue9thode normalis\ue9e d?essai en vue de d\ue9terminer la r\ue9sistance au d\ue9collement des \ue9prouvettes de CAA.Peer reviewed: YesNRC publication: Ye
