Dependence between the width of strip overlap and the strength of joints of one-layer bitumen sheets

Abstract

This paper focuses on the examination of mutual dependence of overlap width of bituminous sheets and the strength characteristics of their mechanically fastened joints. Bituminous sheets with two different widths of overlap and different degree of modification were selected as samples for experimental measurements. They are supposed to be used as single-layer mechanically fastened waterproofing membranes. The aforementioned dependence has not been explicitly documented yet. The aim of this paper is to confirm or to refute a hypothesis that a relationship exists between a different width of overlap of bituminous sheets and the strength of their joints. The formulation of the results was based on the statistical evaluation of laboratory measurement data.
