Road Rehabilitation

This project consisted of works through the Daintree World Heritage Area to restore sections of failed pavement after 2 cyclones and monsoonal rain saturated the area. Restoration of unsealed surfaces and re-sheeting works were required with a layer of 150mm of gravel on the majority of the project.

The project was situated over an area of approximately 75km. Further variations to the contract resulted in extending the bitumen seal on Rykers Rd a further 1.5km

Works were being carried out to certain constraints with environment and cultural protection being major factors, throughout the project over 3000 sandbags and 150 metres of silt fencing were installed. Coordinating the delivery of approximately 50,000 tonnes of gravel to the area, Robinson Civil Group had to work closely with Council and the community to ensure the continuation of gravel supply and the safety of road users. Traffic management was a major factor with the roads being heavily utilised by tourists during construction.

Roads completed include:

  • Banabilla Road
  • Bloomfield Road
  • Buchanan Creek Road
  • Camelot Close
  • Cape Kimberley Road
  • Cape Tribulation Road
  • Carbeen Road
  • Cedar Road
  • Evergreen Road
  • Forest Creek Road
  • Ironbark Road
  • Maple Road
  • Old Forest Creek Road
  • Pandanus Road
  • Quandong Road
  • Red Gum Road
  • Roland Road
  • Rykers Road
  • Spurwood Road
  • Thornton Park Drive
  • Turpentime Road
  • White Beech Road

This project consisted of in-situ stabilising incorporating nom 3% GB cement by mass into the pavement, final trimming to level and associated bitumen sealing works

Roadway improvements have been designed to facilitate B-Double movements along the route which is a designated sugar haul route running between Tolga and Atherton on Marks Lane between Gillies Highway road and Picnic Crossing road

This project consisted of mill and fill asphalt, subgrade treatment and cement stabilisation works.

Traffic management on this project was quiet extensive with one section requiring control for a six point entry round about. The project was completed during the months of February and March 2015 in which time Tropical Cyclone Nathan hit causing disruptions to the project, nevertheless the project was delivered on time and on budget.

  • Working closely with TMR to achieve optimum outcomes
  • Working with continuous one lane of traffic open  
  • In-situ stabilization (using GB cement powder)
  • Complex Traffic Management

Lime process:
  • 2000 Tonne of hydrated lime for road stabilisation consisting of three incorporation passes over two days per lot at a rate of 24.4kgs of hydrated lime per square metre.
Cement process:
  • Daily target of 5000 square metres per day which was met and exceeded at a drop rate of 8.8kgs of cement per square metre.
Polymer Trial:
  • Assisting in the trial of Polymer stabilisation, as this was a first for Cook Shire Council and Robinson Civil Group.
  • Compaction test from the above trial returned positive feedback.
Special Features Of Contract
  • Coordination of delivery of lime, cement and polymer product from Townsville to site
  • Site management and storage of material supply to ensure no interruption to the works

  • Working with three different stabilisation additives



This project consisted of damaged sections of road which were milled out and replaced with 2.1 gravel on a number of sealed roads throughout the Tablelands. The works were then fully sealed with a two coat chip seal. Some medium formation grading was applied to areas of gravel roads.
