Stone mastic asphalt (SMA) is a superior asphalt mix with proven performance. As a consequence of the aggregate skeleton, SMA has an open surface. The experience of some road agency and industry members indicates that the open surface of the SMA…

Stone Mastic Asphalt is coarser in gradation than dense graded asphalt and in emphasising the coarseness of the mix it tends to become difficult to compact in the laboratory. Five compaction methods were investigated to determine how these affected…

The report examines three aspects of stone mastic asphalt mix design. Gradation curves from Europe, US and Australia were reviewed and it was noted that with few exceptions they were relatively similar. The tolerances imposed on the mix designs were…

The primary focus of this study was to assess the stiffening effect of different filler types while using different bituminous binders. The significant influence of filler in the mastic of asphalt mixtures is well known and the effect is more…

This Pavement Work Tip provides a guide to the application of statistical process control charts to the production of asphalt.
