Insitu Stabilisation techniques demonstrate the biggest recycling and sustainability impact in road infrastructure and earthworks through simply reusing existing materials.
The process involves the introduction of small quantities of binders/additives to existing road or earthwork materials with the purpose of improving the engineering characteristics, resulting in improved and more resilient assets.
Insitu stabilisation and pavement recycling is traditionally preferred amongst infrastructure managers due to competitive direct costs and fast construction methods. The environmental and social benefits of pavement recycling remain an important aspect and are being increasingly recognised by the public works sector and the community in general.
Stabilised Pavements of Australia has founded success as a business through its core service of insitu stabilisation and pavement recycling. We are passionate about our pavement recycling services and the genuine sustainability benefits that can be contributed to the communities we live in.
Achieving Sustainability Targets
Are you being driven by Net Zero 2050, Circular Economy or Sustainability objectives and targets?
Beyond direct insitu stabilisation and road rehabilitation services, Stabilised Pavements of Australia are committed to going the extra mile with helping clients maximise sustainable outcomes.
The solutions we provide can assist with achieving targets on the following outcomes in comparison to existing practice:
Recycle up to 100% of the existing asset as all the materials needed for a new road are already there
Sustainability Calculator and Reporting
In the absence of a simple industry-based calculation tool, SPA developed an ‘Environmental Calculator’ to highlight the sustainability benefits of pavement recycling through stabilisation.
The calculator is an Excel based calculation tool and has evolved over 10 years to encompass industry needs. The calculator maintains contemporary underlying modelling principles that align with government and industry standards.
For road rehabilitation options specific to projects, the Environmental Calculator can report:
- Greenhouse gas emissions
- The amount of material reused and recycled as part of the rehabilitated pavement, quantities of primary materials required, and materials removed from site for discarding
- Number of heavy truck movements to and from site for haulage of materials
The scope of calculations covers:
- Material manufacturing (cradle-to-gate)
- Construction activities
- Transport and haulage
SPA has subsequent capability to provide targeted sustainability reporting that can be integrated into other project related information such as pavement design, construction methodology and construction budgeting for overall cost benefit analysis of respective potential treatment options.
