A Combination of mill out and replacement of existing pavement with 250mm of cement modified base and 200mm overlay of 2.1 gravel and insitu stabilize to 300mm with 1.5% GB Cement.

Bullaburra Road

Overlay existing road with 150mm of 2.1 gravel and insitu stabilize with 1.5% GB cement.

Work areas were sealed and the road line marked.

This project consisted of works through RoadTek to restore the Peninsula Development Road after 2 cyclones and monsoonal rain saturated the area. Restoration of unsealed surfaces and re-sheeting works were required with a 150mm layer of gravel on various sections of the road from Coen south to Lukin River, a distance of approximately 40km.   Works were carried out too certain constraints with traffic being a major factor as the road was heavily utilised once reopened to the public after the wet season.

Due to the works completed to a high standard, Robinson Civil Group is called on yearly to help assist in the reopening of the Peninsular Development Road reaching RoadTek’s milestone of 4km per day.
