Determination of Mass of Bitumen in Bitumen Sheets by Calcination Metod

Original language description

The work analyses the problem of determination of the mass of bitumen in waterproofing membranes - bitumen sheets by method of the calcination. The waterproofing function in bitumen sheets is ensured by the bitumen mass. The amount of bitumen mass is not prescribed in the European standards for bitumen sheets. The amount of bitumen is specified in some national standards. The amount of bitumen was determined by the extraction method and the calcination method for bitumen sheets and the sample of bitumen coating. The calcination method is not described in the standards, only in the forthcoming standard P EN 544 for bitumen sheets. To compare the two methods, the sample of bitumen sheet and a sample of bitumen coating material were used. The coating of bitumen sheet and the sample of bitumen mass were elastomeric character (SBS). The bitumen coating of known composition was prepared in the laboratory. By comparing results of both methods, it was found that the mass of the bitumen obtained from the bitumen coating material by extraction was 0.7 % higher than the mass of the bitumen obtained by the calcination method.This small difference was due to the fact that the same amount of bitumen coating was tested. During the testing of the bitumen sheet, it was found that the calcination time of 2 hours according to P EN 544 is insufficient for the calcination of bitumen sheets. The mass of the bitumen obtained from the bitumen sheets by extraction was 0.6 - 1.3% lower than the mass of bitumen obtained by the calcination method. The termination of the calcination was performed when the weight loss of the test specimen was less than 0.03 g. The time of the calcination of the bitumen sheet and the bitumen coating material, with a comparable amount of bitumen material, differed by 0.5 hour, for the calcination of bitumen sheets at least 4 hours. The P EN 544 methodology cannot be used. The difference in the results of both methods was 0.6 - 1.3 % depending on the considered mass of bitumen of the carrier. The higher difference between the two methods is due to the different thickness and the mass of bitumen of the test specimens. In contrast to the bitumen coating material, the mass of bitumen of the bitumen sheet differed for both methods. Furthermore, it was found that the weight and arrangement of the test specimen in the incinerating dish has an effect on the time of the calcination. The calcination method is as the time consuming as the extraction method for bitumen sheets with the bitumen coating material of elastomeric character. The extraction method is more accurate.
