Overview of Presentation
§ What is the APS-fL Project?§ Drivers of AAPA Innovation§ Perceptions of Value§ Project in the Context of Innovation Driving Value§ Nurturing the Project§ Value Deliverables § Learning Points for Future
AAPA and Long Life Asphalt Pavements in Australia
§ LLAP Projects and studies between AAPA and SRA’s since 1980’s§ Regular positive reports on the studies - Sharp & Tepper 2001 - Youdale 2004 - Foley 2008 - Rickards 2009 - Armstrong & Rickards 2010
§ Great reports but nothing changes! Austroads revisions delivering conservative outcomes
§ Over designed but by how much? § This project changes that forever§ Absolutely about innovation driving value
What makes AAPA tick? Drivers of AAPA Innovation
§ AAPA is the peak body representing all parts of the flexible pavement industry in Australia since 1969. Member categories embrace bituminous binder suppliers, asphalt producers, sprayed sealing operators, equipment suppliers, consulting firms, toll road operators, all State Government Road Authorities and many Local Governments across Australia.
§ Mission – to effectively represent the interests of all members and to demonstrate technical excellence in the sustainable use of bitumen-based products in pavement engineering solutions
§ Values – in all its activities and at all times AAPA and its members will act with professionalism, honesty and integrity
Strategic Directional Alignments – the Context
SRA Guiding Values
§ Safety§ Customer Focus§ Efficiency & Effectiveness§ Collaboration§ Integrity & Transparency§ Innovation & Harmonisation§ Sustainable
AAPA Strategic Goals and Values
§ Sustainability & Safety§ Technology & Leadership§ Communication, Outreach & Effective Representation
§ Training & Knowledge§ All Member Focus§ Honesty & Integrity
Consideration of Value Perceptions
§ Value? More benefits for less or same costs?§ Benefits? Not universally perceived e.g. Smoothness e.g. Noise§ Costs? Impacts? Whole of life assessment?§ Value for money outcomes are defined by those motivations clients regard as benefits§ Our drivers give us the clear goal to innovate and seek out innovations that provide value solutions in terms of meeting the goals of our clients
§ Community expectations – OUR Challenges – this project§ Freeways
§ Free flowing (safe system guidelines)§ Smooth to drive on – with low noise§ Safe - no spray when it rains, good skid resistance§ Well maintained
Project Nurturing - Engagement with SRA’s and ARRB
§ Early stakeholder engagement§ Project Steering Group§ Dynamic Modulus v Resilient Modulus§ Sample compaction method§ Healing and NCHRP Project 9/44§ Plant mixed samples§ Over-reliance on NCAT data§ UK data and curing§ FEL incorporation§ Field validation§ Composite & other pavements
Tension Points(Harmonised?)
Executive Visions§ Customer Focus§ Efficiency & Effectiveness§ Collaboration§ Integrity & Transparency§ Innovation & Harmonisation§ Sustainable
Technological Divisions§ Terrors of Risk§ Collectives of Performance§ Fearsome “Trust” word§ Mask of Consensus§ Passion to Preserve § Lust for Research Funds
Value Deliveries of the Project?
§ Safety§ Cost effectiveness§ Sustainability§ Innovation§ Harmonisation§ Smoothness§ Whole of life benefits§ Maintenance
§ Traffic at maintenance plus texture & spray§ Pavement thickness savings plus time§ Virgin material savings plus recycle & noise§ Australian & state of the art internationally§ Applicable nationally§ Initial and perpetual via mill & fill§ Smooth, fuel savings, congestion avoided§ Limited to the wearing course – perpetual pavement
Example of thickness outcomes(150mm working platform on subgrade CBR 5)
§ Austroads 100x106 (SAR)355mm (Melbourne)390mm (Brisbane)
§ UK TRL 340mm (DG 50 pen)390mm (DG 100 pen)
§ Australian Pavement Solutions - for Life 325mm (Mel) 320mm (Bris)
Project Outcomes – Takeaways
§ This work has never been done before in Australia – uniquely field validated§ It was broadened & enriched by SRA and ARRB input & undertaken in close collaboration
§ It has been peer reviewed as being work of eminent international quality§ The benefits it contains for asset owners and road users can not be ignored –in terms of cost & sustainability
§ Six for the cost of five§ Most timely given the infrastructure boom§ Implement nationally quickly - Bevan’s following papers
Learning Points for Future Value
§ Early engagement highly beneficial and across the right levels§ Open exchange and sharing of objectives and information§ Develop and maintain a bias for action with supporting performance criteria§ Focus on technology transfers for earliest achievement of the value benefits§ Gain commitment to national implementation at the outset§ Literature surveys not always needed as paid research§ Express project linkages to Asset Owner vision elements§ Identify, measure and tell community benefits of project§ Planned and targeted communications and reviews§ Great value gains from international affiliations § Just keep looking and doing it for ongoing improvements
