Horizontal geometry/superelevation design of pavement overlay
Council requires the horizontal geometry/superelevation design of pavement overlay (typically, recycle 100mm of additional new base material with existing pavement base material) for the following roads:
• Sodwalls Road (Ch 5700 – 13911)
• Magpie Hollow Road (Ch 3100 – 5080)
• Lowther Siding Road (Ch 0.0 – 3263)
• Cooerwull Road (Ch 200 – 480)
• Hartley Vale Road (R347) (Ch 0.0 – 1560)
• JR Street (R348) – “Town” [Continuation of HV Rd 347] (Ch 0.0 – 253)
• Browns Gap Road (Ch 2900 – 5690 & 6720 – 8720)
• Blackheath Creek Road (Ch 0.0 – 2450 & 3100 – 4633)
• Wolgan Road - Lidsdale (Ch 2960 – 4370)
Council requires sufficient design documentation to allow construction of a pavement overlay/recycling, including typical cross sections, superelevation and transition details.
Lithgow City Council is undertaking a 6 year program to reseal and rehabilitate the council’s road network. The 2025/26 year program is underway and includes 9 road requiring full length or partial reconstruction/recycling of the unbound pavement. To date the subject roads have been investigated using FWD and Borehole testing. Borehole Testing is ongoing and the results are becoming available on a “road by road” basis for pavement rehabilitation design. It has become evident that pavement rehabilitation may require a change in road level, and so Council requires the assistance of an experienced road designer.
