Pavement Design

A detailed geotechnical field investigation (test pits/boreholes, DCP testing, bulk sampling etc.) and laboratory testing of the samples collected during field investigation is required for a suitable pavement design.

 

Greywacke understands the need of  individual sites and provides cost effective designs without compromising on quality and durability of the pavement. Designed so that it may suit your requirements, the ground conditions and intention.

​

We provide expert advice on suitable pavement design for any project based on our pavement field investigation & laboratory testing for both new residential and industrial development and upgrading of existing roads. Greywacke Geotechnics have undertaken numerous investigations for councils and developers, ranging from new sub-divisional sites to  upgrading of existing public and private roads.

​

The purpose of our field investigation and laboratory testing is to assess the subsurface conditions and therefore enable us to determine options for appropriate treatments, based on our findings and information supplied.

​

The findings of our field investigation, testing, pavement design analysis and recommendations is presented by our engineers in a formal report which can be submitted or referenced within tender documents. 

​​

We can offer pavement designs for both existing roads requiring structural upgrading, rehabilitation, reconstruction and/or for new construction including subdivisions, access road, driveways and commercial roads. 

We can undertake geotechnical field investigations for:

​​

  • Minor Roads

  • Local Access Roads

  • Collector & Distributors Roads

  • Car parking facilities

  • Commercial & Industrial Premises

  • Residential & Industrial Subdivisions

  • Pavement upgrading or rehabilitation

​

We can offer a wide range of pavement design options to match your project needs including:

​

  • Flexible bituminous pavements

  • Flexible asphalt surface pavements

  • Pavements incorporating cementitious additives

  • Pavements incorporating foam bitumen stabilisation

  • Sub grade improvement options to reduce granular material requirements or to allow construction to proceed

​

  • Rigid reinforced concrete pavements

  • Concrete segmental pavements
