N2  - Compaction is one of the most important parameters that affect the properties and performance of asphalt mixture. The aim of this study was to investigate the effects of TCR on the gyratory compaction of stone mastic asphalt (SMA) mixture. Samples for performance tests were prepared using Superpave mix design method. A 40 mesh TCR powder was varied from 0 to 2.5  by weight of the total mix with 0.5 increment. Several analyses including the volumetric properties of SMA, resilient modulus and Marshall Properties, stability and flow were tested for both control and rubberized mixtures. The results showed that as the amount of TCR increased the number of gyrations required increased and the drain down of the binder decreased. The rubberized samples showed better stability, resilient modulus and drain down resistance than the control samples. The Optimum amount of the TCR was found to be 0.9 of the total weight of the mix that corresponds to the 72 number of gyrations. That optimum fulfils the Superpave mix asphalt method requirements in terms of air voids, volumetric properties, resilient modulus and Marshall Properties, stability and flow. © IAEME Publication.
