Governments, transport agencies, and industry have identified the need to reduce waste going to landfill and increase the use of recycled materials to achieve more sustainable development and improve outcomes for communities. The latest update to the Guide to Pavement Technology Part 4E: Recycled Materials covers the advancement in material re-use that has occurred in the 13 years since the 2009 version of the guide was published.
There is wide concern around the misuse of recycled materials in road construction, and it is generally agreed that roads should not be viewed as alternative avenues for waste disposal. A protocol has been established that follows a step-by-step process for quantifying the effect of using novel, post-consumer and industrial wastes or recycled materials in asphalt pavements and sprayed seal surfacings.
This webinar will cover the following key updates made to the Austroads Guide to Pavement Technology Part 4E: Recycled Materials:
- Latest and emerging recycled materials utilised within pavements and information on their use in specific applications as well as associated issues, risks, and considerations.
- The developed holistic assessment framework for the use of recycled materials in road pavements.
- The developed protocol for asphalt and sprayed seals that establishes a step-by-step process for quantifying the effect of using novel, post-consumer and industrial wastes or recycled materials.
The webinar will be presented by Phil Herrington from WSP New Zealand and Brody Clark from WSP Australia with participation of Grant Bosma from Waka Kotahi NZ Transport Agency and Mike Pickering from the Queensland Department of Transport and Main Roads.
There will be question and answer opportunities during the session.
Phil Herrington is Technical Principal at WSP New Zealand with 35 years’ experience in road surfacing and materials research, specification and product development. He has in-depth expertise in the chemistry and rheology of bituminous binders and their relationship to the engineering performance of road surfacings. He has published widely in the international scientific and engineering literature. A focus of Phil’s work is the need to improve the sustainability of road construction practices and the potential opportunities and challenges arising from the use of recycled, waste and renewable materials.
Dr Brody Clark is an award-winning chartered pavement engineer working on infrastructure projects all over Australia and has an extensive material research background. Brody is spearheading the research and development field for pavements within WSP Australia and while working full time completed his PhD thesis in pavement engineering. Brody published multiple papers from his studies and has presented his research at multiple international conferences. Brody is passionate about applying his sustainable pavement research background into the real-world projects he delivers.
Grant Bosma is the Principal Surfacings Engineer for Waka Kotahi NZ Transport Agency. He has held this role for the past four years following a 36 year career in the road contracting industry. Grant’s areas if interest cover civil materials including bituminous binders and mixes, aggregates and pavement construction, the sustainable use of resources, matching material properties to the pavement demand, and the use of recycled materials in road pavements and surfacings.
Mike Pickering is currently working in the role of Director (Pavements, Research and Innovation) in the department of Transport and Main Roads Queensland (TMR) and has over 30 years of experience in road infrastructure, including in pavements, planning, (geometric) road design and road drainage. The Pavements, Research and Innovation team, amongst other things, provides expert advice and technical documents, for TMR projects, related to new pavements and their design; many pavement materials and products – such as asphalt, seals and unbound pavement; and related pavement innovations. Sustainability and the potential to use recycled materials in pavements is ongoing area of interest to the department. Updates to unbound granular and asphalt pavement specifications, and the publication of a recycled glass aggregate specification, are examples of changes made to facilitate increased use of recycled materials in departmental projects.
