Adhesive blister propagation under an orthotropic bituminous waterproofing membrane.

Highlights: [•] The orthotropic property of the PBM creates an elliptical blister propagation front. [•] The orthotropic material property of the PBM is measured using biaxial test. [•] We determined the energy for elliptical adhesive blister propagation. [•] Blister propagation is proportional to orthotropic ratios of the two elastic moduli. [ABSTRACT FROM AUTHOR]
