Tender Advertisement #1300770

PURPOSE:
The purpose of this project is to develop accurate, and technically-based guidance on the design and performance of foamed bitumen stabilised (FBS) pavements.

SCOPE:
This project will continue the work from Austroads projects APT6157 Laboratory fatigue characterisation of foamed bitumen stabilised materials and TT2046 Improving the cost effectiveness of foamed bitumen stabilised pavements to develop further understanding of foamed bitumen behaviour and provide valuable information to address critical knowledge gaps:
• Evaluate parameters by undertaking a proof of concept that includes end user (pavement designer/practitioner) project specific examples based on project specific designs to compare thickness differences.
• Research testing proposed to provide further opportunity to calibrate the APT6157 laboratory developed fatigue relationship with ALF/field performance. Varying climate conditions to develop temperature relationships and appropriate shift factor/s.
• Investigate the influence of bitumen content and temperature on the fatigue performance of FBS materials and further refine the laboratory fatigue performance relationship for FBS materials over a range of temperatures (for example, 15°C to 35°C). Varying compaction conditions to develop density relationships and appropriate shift factor/s.
• Investigate the strain relationship between four point fatigue beams and large scale wheel tracking (strain gauge instrumented).
• Investigate the reliability factor for FBS material.
• Incorporate validation testing from NACOE and WARRIP supporting projects.
The scope of this project includes further research and development undertaken to update the Austroads Guide to Pavement Technology (AGPT) Part 2: Pavement Structural Design and Part 5: Pavement Evaluation and Treatment Design with more accurate design requirements and a performance model of FBS pavements. Relevant developments from this project (and learnings from previous Austroads projects) can be documented into AGPT Part 4D: Stabilised Materials.

DELIVERABLES:
This project will produce the following final deliverables:
• Updated versions of Austroads Guide Parts:
o Guide to Pavement Technology Part 2: Pavement Structural Design
o Guide to Pavement Technology Part 5: Pavement Evaluation and Treatment Design
o Guide to Pavement Technology Part 4D: Stabilised Materials.
