Esperance Coast Road is situated south of Hobart in the Huon Valley Council, the southernmost local government council in Australia. The coastal road was developing several signs of deterioration including deformation, cracks and edge failure.
To mitigate the issue, Huon Valley Council engaged consultants to undertake pavement investigations focussing on the section between the Huon Highway and Police Point Road. Esperance Coast Road runs through a hilly area with a high slope on one side and a valley on the other. The current pavement was eroding due to high surface runoff and lack of horizontal drainage. Water was ingressed in the pavement, reducing the structural capacity of the pavement layer to carry traffic load.
