Popis: 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 elevated temperature is. Bitumen sheets, which are used in the Czech and Slovak Republic, were used as samples. The samples represented bitumen sheets modified with polymers of elastomeric and plastmeric nature. Bitumen sheets were of two types with and without protective covering. It was found that fly ash and micro-milled limestone were used as fillers in the bituminous substance of the sheets. The dependence between the amount of fillers and the resistance to flow at elevated temperature was only confirmed in some of the bitumen sheets samples.
