“…For the UK data set, when long-term ageing in the oven was conducted, the increase in shear force was up to 12 kN or shear stress of 0.7 MPa. This result is also comparable to long-term in situ ageing of 10 years as in an investigation by Raab et al (2012), as depicted in Figure 15. In this figure, it can be seen that the shear force increases by 22.5 kN or the shear stress increases by 1.3 MPa.…”

“…As we know from other studies, this is true as long as traffic volume and percentage of heavy traffic meet design limits. If traffic volume exceeds the design limits over a certain period of time, the pavements start to deteriorate, often leading to visible distress phenomena, such as cracking and rutting, which are measurable in a decrease of shear strength (Raab et al 2012). .…”

The paper focuses on the question of the influence of age on the interlayer bonding properties of two-layered specimens. The evaluation combines traditional data evaluation and artificial neural network (ANN) analysis of different data sets of pavements from Switzerland, United Kingdom and Italy. The results show that it is possible to use ANN techniques to derive models from data sets and to predict interlayer bond strength. The findings demonstrate that age has a positive effect on the interlayer bond of asphalt pavements and that long-term oven ageing can lead to similar results as in situ ageing. In addition, it was found that the positive effect of ageing is greater when a tack coat is used.

The following recommendations are based on the chapter III of a State of the Art review conducted by the Task Group 2 of the RILEM Technical Committee 241-MCD ''Mechanisms of cracking and debonding in asphalt and composite pavements'' (Petit et al in Mechanisms of cracking and debonding in asphalt and composite pavements. Chapter III of the State-of-the-Art report of the RILEM technical committee 241-MCD series, vol 28. Springer, New York, pp 103-154. ISBN 978-3-319-76848-9 2018). The recommendations mostly concern "pure" fracture mode test methods that are currently used worldwide and even standardized, while mixed mode test methods developed by few research teams have not received full attention. This paper intends to give guidance for the application and characterization of interlayer bond testing, looking at the appropriate test methods and the importance of influencing parameters.
