LINTRACK RUTTING RESEARCH PROJECT - TRIAXIAL TESTING PROGRAM

In the framework of a three-year rutting research program performed in the Dutch LinTrack accelerated loading facility, all asphalt mixes that were tested in the test pavements were also subjected to an extensive laboratory triaxial testing program. It was found that the poorly performing materials showed much scatter in the test results and showed hardly any logical trend in the deformation behaviour. Especially the lack of a positive effect of high confining stresses was notable. For the materials that showed a better resistance to permanent deformation, the scatter was usually more limited although outlying results were still found. Also, these materials usually showed a quite logical trend in the results. The ranking of the behaviour of the wearing courses in the triaxial tests corresponded well with the behaviour in the test pavements. It was concluded that triaxial testing is suitable for distinguishing between mixes of better and worse rutting resistance but the scatter in the results requires that sufficient test repetitions are done. The correlations between the behaviour of the test samples and their material composition were generally quite weak. For the covering abstract see ITRD E118503.
