Dimensional stability of reinforced bitumen sheets as a possible source of flat roof defects

Popis výsledku v původním jazyce

This paper follows up on the results of a research presented at the conference Building Defects 2017. The paper deals with the dimensional stability of bitumen sheets. The manifestation of insufficient dimensional stability is the shrinkage of bitumen sheets in the transverse joints. Shrinkage of bitumen sheets with a non-reinforced glass fiber reinforced polyester liner is primarily due to insufficient technological discipline. The paper deals with the influence of melting of the sheet on its possible shrinkage during roof exposure. Previous research has shown that the shrinkage happening during melting accounts for more than 50% of total shrinkage. The aim of this paper is to show the size of the effect on the biasing of the load-bearing insert during the realization of the waterproofing layer in bitumen sheets with a glass-reinforced polyester support liner. The experiment, expressed by the dimensional stability test according to ČSN EN 1107, was performed in a laboratory on three samples of bitumen sheets. Bitumen sheets had different types of reinforcement and a different weight of the carrier liner. In contrast to the previous research, the test temperatures were extended beyond the scope of ČSN EN 1107.
