Influence of the quantity of fillers on crucial thermal-technical parameters of bitumen waterproofing sheets

Original language description

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 sheets. The amount of bitumen filler is mostly limited by the technological capabilities of the production equipment used in the production of bitumen sheets. However, the amount of filler can adversely affect some properties of the bitumen mass and hence the bitumen sheets. One of the basic features influencing the application of bitumen sheets is a low temperature flexibility. An increased amount of fillers also degrades workability in the work place. This paper deals with the analysis of the composition of the bitumen mass for the production of bitumen sheets used for the isolation of concrete bridges. The paper based on the analysis of samples of bitumen sheets selected from various manufacturers describes the usual amount of bitumen fillers. At the same time, the paper answers the question of the hypothesis - whether the increased or decreased amount of fillers affects one of the basic thermal-technical properties of bitumen sheets - the flexibility under low temperatures. The authors of this article found during the previous research that dependence is influenced both by the type of bitumen mass and by the type of the surface treatment. It has been statistically proven that the decisive factor is not the amount of the filler but the type of bitumen in the terms of modification. The aim of this paper is to confirm or confute the hypothesis that there is some relationship between low temperature flexibility and the composition of bitumen with an expanded amount of samples. Thus, new results can confirm or disprove previous research results. Results were formulated based on the statistical evaluation of data obtained from the laboratory measurements.
