    This paper presents new uniform model for compaction propagation generated by impact and gyratory compactor. Currently European standard EN 12697-10 defines two different models, independently for an ... impact compactor and for a gyratory compactor. There is no correlation between those two standardised models. In our previous studies it has already been established that the model defined in EN 12697-10 for impact compactor does not appropriately describe the compaction process. The prediction of the compaction, especially at the end of the compaction process, differs from the experimental results of the compaction tests, which was confirmed on several different asphalt mixtures. In order to achieve improved predictions, new research was performed on AC asphalt mixture of different gradations. Comparative compaction was performed on gyratory compaction device according to EN 12697-31 and impact compaction device (Marshal Compactor) according to EN 12697-30. Based on the results of these tests an improved model for the compaction propagation is proposed. It consists of two parts and results in good fitting of experimental data for either compaction process. The improved new model may be universal for both methods of compaction and may offer a supplementary solution to the one currently standardised and specified in EN 12697-10.
