The paper deals with the correlation between the amount of fillers and the thermal resistance of bitumen sheets under EN 1110:2011. Based on the analysis of samples of bitumen sheets used for the insulation of concrete bridges, the standard EN 14695:2010 indicates what the usual amount of fillers is and what the value of the resistance to flow at e...

This paper deals with the problematics of the surface temperature of flat roofs, where the waterproofing layer is used as polymeric waterproofing membrane of softened PVC. Currently, it is possible to encounter defects on flat roofs due to the high surface temperature of the waterproofing layer. The consequence of such a high surface temperature is...

Bitumen sheets are mainly used in the building industry as a waterproofing material. The waterproofing function in bitumen sheets is ensured by the bitumen mass and its quantity and composition. The important component of bitumen mass is the filler. An increased amount of filler reduces the cost of bitumen and thus the cost of a complete bitumen sh...

Bitumen sheets are isolating materials that are used in the building construction, primarily as roof waterproofing, vapour barrier and waterproofing of the substructure. For civil engineering they are applied as the isolation of concrete bridge decks and they are used as the main waterproofing for underground construction. Currently, bitumen sheets...

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 reinforced polyester liner and a...

This paper deals with the surface temperature problem of flat roofs, where bitumen sheets are used as the final waterproofing layer. Currently it is possible to find defects due to the high surface temperature of the waterproofing layer on flat roofs. The result of such a high surface temperature is, for example, the release of bitumen sheets and t...

One of the frequent sources of flat roof faults is failure of the top layer of a multilayer bitumen sheet system in cross-connections. One of the possible causes of this disorder is failure to observe technological discipline. The paper deals with how the full melting of the bitumen sheet influences its possible shrinkage during the roof exposure....

This article focuses on the frequently discussed topic how to make the frontal joints of bitumen sheets with coarse-grained surface coating. Bitumen sheets have a spill in the place of these joints. Insufficient strength of the frontal joint is one of the possible faults in waterproofing using bitumen sheets. The paper compares different ways of pe...

This paper is based on research dealing with defects that appear on concrete bridge decks with an insulating layer from asphalt strips on the interface between the asphalt strip and its basis. The durability and lifespan of the bearing structure of concrete bridge is determined by insulating layer that constitutes, together with the primary layer a...

This paper deals with the investigation of the interdependence between the flow resistance at elevated temperatures for reinforced bitumen sheets and softening points of bitumen matter softening point in these reinforced bitumen sheets. Reinforced bitumen sheets, which are used for waterproofing isolation of concrete bridge decks, were selected as...

The aim of this report is to evolve the suggestion for determining the limiting value of the qualitative requirements for the flow resistance during high temperatures for reinforced bitumen sheets that are used as the waterproofing of the concrete bridge decks due to EN 14695:2010 and ČSN 736242:2010. Suggested revisions of the standards will lead...

This contribution deals with the issue of the weight absorption of bitumen waterproofing sheets. The aim is to determine which parameter the weight absorption depends on, according to the laboratory measurement and the statistical evaluation. This dependence is to be examined based on the results of the weight absorption achieved by the two differe...

This contribution deals with the quantity of fillers in bitumen waterproofing sheets used for waterproofing of concrete bridge decks. The contribution shows on samples of bitumen waterproofing sheets from various manufacturers what the usual quantity of filler is in these products. The contribution also answers to the hypothesis whether increased o...

The article deals with the issue of weight water absorption of bitumen waterproofing sheets. It compares two methodologies applicable to examination of water absorption of bitumen waterproofing sheets from the point of view of testing procedures. It compares the results of both the methods for individual bitumen sheets upon experimental measurement...

This article deals with determination of bulk density of bitumen waterproofing sheets using different methods, namely calculation and experimental measurement. Volume density actually well reflects bitumen sheet composition. Composition of bitumen sheet is the factor that influences the hydro insulation function.
