In-situ road stabilisation on the Mid North Coast

The MidCoast LGA runs from the coast at Forster and Tuncurry, across the Manning River floodplain around Taree, and up into the ranges toward Gloucester and Krambach. The pavements reflect it. On the coastal strip, sandy soils and a high water table call for the same treatment as Port Stephens: cement or slag/lime to give a granular base cohesion. On the Manning floodplain, alluvial clays hold water and move, so lime treatment of the subgrade comes first, then the base. Inland, on roads like The Bucketts Way, the terrain is steeper, the material variable, and a large share of the rural network is unsealed with the maintenance budget spread thin. The region was hit hard by flooding in recent years, and much of the rehabilitation work now funded is betterment: rebuilding roads stronger than they were rather than like-for-like. In-situ stabilisation suits that brief. It binds the existing pavement into a stronger, less moisture-sensitive layer for around half the cost of reconstruction.
