Data collection for the 2nd generation of European bitumen standards in the Czech Republic – round robin test experience

Popis výsledku v původním jazyce

The second generation of European standards for bituminous binders will include, largely, those performance-related characteristics, which have been gradually implemented in practice. With respect to the regular use though, the characteristics have been recognized as a new requirement. Long-term experience with determination and interpretation is still missing. Due to the fact that polymer modified bituminous binders (PMB) in particular have become a standard product for all types of asphalt mixtures, it is necessary to stipulate the basic requirements for particular binders specified in the standard and based on their characteristics. Extensive data collection over all of Europe has gone on for several years. The main expectation is for laboratory data to provide sufficient information for the proposed initial set of the required parameters to be potentially included in the standards. The Czech Republic has started to gather experience and values based on round robin tests as well. The first stage of the project was launched in 2014 and 3 laboratories have tested two binders from different bitumen producers - virgin, short-term aged (RTFOT) and long-term aged (RTFOT + PAV). Traditional and performance analyses were employed. The second stage of the project followed in 2015; there were already six participating laboratories. Four binders were tested (one paving grade, three PMBs) in a similar framework as in 2014 with the addition of some conditions (e.g. testing temperature on DSR, BBR test etc.). The last stage in 2016 included six laboratories and four binders again (one paving grade, three PMBs). The last stage involved a further extension of test temperatures on DSR, and included a new addition of different temperatures and further stress level for the MSCR test (8 kPa). The evaluation of all results has led to the conclusion on a broader data collection for all polymer-modified binders in use in the Czech Republic.
