SUGGESTION OF LIMIT VALUE OF FLOW RESISTANCE FOR REINFORCED BITUMEN SHEETS AT ELEVATED TEMPERATURES IN TERMS OF TYPE OF COATING

Original language description

This article is the continuation of the paper published at the conference SGEM in 2016. European product standards generally do not specify the qualitative requirements for individual product characteristics. EN 14695:2010, which deals with the waterproofing of concrete bridge decks, is not an exception. The national standard CSN 736242:2010 sets quality requirements for bitumen sheets. This standard doesn't take into account in its qualitative requirements the type of the modification of bitumen coating - the mass modified by plastomers and elastomers. We find this consideration which is used abroad important because the higher value of the resistance against the flow can strongly affect the quality of bitumen sheets not only from the functional point of view but even from the applicability perspective. The effect of the modification is also known, for example, when applying reinforced bitumen sheets in compositions of flat roofs. Currently the database of bitumen sheets was extended by other samples with different coating material of both the elastomeric and plastomeric material. The research was thus focused directly on the determination of limit values of flow resistance at elevated temperature for the type of coating material. Values for the quality requirements will be specified on the basis of the statistical evaluation of the data obtained by laboratory measurements of samples - bitumen strips collected in the years 2012 – 2016. Proposed limit values could be able to serve as a basis for revising the standard CSN 736242: 2010 and this topic represents the main aim of this paper.
