6. Construction ramps up in the Southern Interchange
Completion of the two new lanes in and out of Hamilton will tamp up before and after Christmas.
We are placing and compacting a new blend of aggregate called Hi-Lab that provides a more robust road foundation than traditional aggregate blends. It consist primarily of large rock, with enough finer gravel, sand and cement to bind the rock in place when it is compacted.
Starting in December, we will begin laying two layers of asphalt on top of the Hi-Lab. This will be carried out at night, when traffic volumes on SH1 are lighter and won’t interfere with the works or asphalt supply.
