Granular Overlay
Rip, reshape and addition of granular pavement material (typically 150mm rule of thumb). Finished off with a Sprayed Seal wearing course. Generally a treatment applied to Rural roads. Pavement failures and/or insufficient cover to subgrade. Where a bituminous seal will not rectify the current defects. Also to fix shape corrections. Where there is insufficient batter widths or the treatment will result in a reduced lane width that is not acceptable to current traffic volumes. Also where there are level limitations in the form of kerb and gutter.
