The primary difference in placing SMA, compared to DGA is in compaction procedures. Multi-tyred rollers are not used due to the possible working of binder-rich material to the surface of the asphalt and consequent flushing and pick-up. Trafficking of the newly placed asphalt while still warm may have the same effect and it is generally preferable for surfaces to cool below about 40 °C before opening to traffic. The preferred method of compaction is to use heavy, non-vibrating… WebMay 9, 2016 · Asphalt concrete mixtures cool quickly so it’s important to compact while the mix is hot.
