Outcomes from RILEM TC 237-SIB TG1 on the affinity between aggregates and bituminous binders
Abstract
Water damage is one of the key aspects related to pavement durability. It leads to ravelling and loss of integrity especially for asphalt pavements. There are numerous test methods that aim to address this, either with respect to binder, aggregates or the combination of both, as loose or compacted mixture. The RILEM technical committee, TC 237-SIB, focused on testing and characterisation of Sustainable Innovative Bituminous (SIB) materials and systems. Within this TC, Task Group 1, TG1, focused on bituminous binder testing and more specifically on the affinity between aggregates and bituminous binders and test methods. One of the main purposes was to run a Round Robin Test to evaluate the reproducibility and repeatability of these test methods and to give recommendations for improvement. A total of 13 laboratories participated from Europe and North America. This paper summarises the main results comparing, amongst others, the rolling bottle test and boiling water stripping test according to EN 12697-11. Three asphalt binders were selected, two unmodified and one polymer modified binder, along with four aggregate types with different mineralogy. This paper provides the key results on the evaluation of the test methods related to test procedure, measurement and interpretation of the results. The outcomes show that, while some qualitative trends are seen, there is still a large scatter in results both within the same test method and between different test methods. Thus, it is hard to consider these methods as giving essential characteristics for defining the specifications of bituminous materials. This does not come only from visual interpretation. The overall recommendation is to relate the results to qualitative classes.
