Abstract
The work deals with the problem of determination of mass of bitumen (bitumen polymer) in bitumen sheets. The component influencing waterproofing ability is bitumen. For this reason, in some countries there are defined requirements for the mass of bitumen in bitumen sheets. This contribution shows the possibilities of how to determine the mass of bitumen in bitumen sheets. The methodology for determining mass of bitumen is based on a comparison of test procedures specified in the standard ČSN 730605-1 and DIN 52123, where the mass of bitumen is determined by extraction and indicates the insufficiency in current legislation where the extraction method is not sufficiently described. The work specifies the extraction method by precisely defining aids and procedures and focuses on the possibility to replace trichloroethylene with another solvent in order to limit the use of this solvent. The work compares the measured results of mass of bitumen for two samples of bitumen sheets (modification by plastomers and modification by elastomers) in for three selected solvents (trichloro-ethylene, xylene and toluene). Mass of bitumen was determined always within 24 hours. The results are comparable with the following specification. Sheets with Styrene-butadiene-styrene (SBS) polymer show a smaller standard deviation and xylene more accurate results in the relation to trichloroethylene. Economic costs for extraction in the case of xylene represent 331 % of the costs and in the case of toluene it has reached 158 % costs of the compared to using trichloroethylene. Xylene and toluene are comparable in terms of the medical harmlessness. The work is in the first phase of the research, which in the next stage will deal with another way to determine bitumen in bitumen sheets by using of the calcination. © 2021, Petroleum and Coal.
