Recommendation of RILEM TC 241-MCD on interface debonding testing in pavements

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.
