Description:

Studies have been completed to verify the predictive capabilities of European hot mix asphalt testing equipment by performing tests on mixtures of known field performance. The results indicated that the Hamburg wheel-tracking device and the French rutting tester have the ability to model field performance very well. The purpose of this study was to compare test results from the European testing equipment using laboratory compacted samples and field compacted samples. The results from this study 1) helped to decide how close the laboratory compactors "simulate" field compaction, and 2) assisted with the development of specifications for field acceptance testing. When tested in the French rutting tester, samples compacted in the French plate compactor and linear kneading compactor produced samples that gave very similar test results to field compacted samples. When tested in the Hamburg wheel-tracking device, results from the laboratory compacted samples indicated the mixes would be more resistant to moisture damage than the results from field compacted samples. The air voids in the field compacted samples were more uniformly distributed than those in the laboratory compacted samples.
