October 21, 2020 By ORBA
Mississauga, Ont. – The Ontario Asphalt Pavement Council (OAPC), a council of the Ontario Road Builders’ Association (ORBA), published its list: The Top 10 Ways to Get More Durable Hot Mix Asphalt Pavements.
- Do Your Homework
- Encourage Mixes That Have Higher Asphalt Cement (AC) Content
- Specify a Finer Gradation for your Mix Type
- Don’t Over Heat the Mix
- Include Adequate Surface Preparations in the Plans
- Ensuring Adequate Pavement Bond
- Provide Proper Pavement Density
- Producing Uniform and Consistent (Quality) Mix
- Use Rap Responsibly
- Complete Quality Assurance (QA) Testing and Inspection
The OAPC developed the list from results of the Quality of Asphalt Review (QAR), which commenced in September 2018. The QAR was commissioned in the fall of 2017 and was managed by KPMG and consisted of analysis conducted by Texas A&M Transportation Institute (TTI).
“The Top 10 List was announced shortly after the completion of the QAR in 2017 as part of the road map outlined by the QAR for continuous improvement in asphalt pavements. It does not include everything that can negatively affect a successful paving operation, yet provides a useful top-level summary,” said Doubra Ambaiowei, ORBA technical director.
The Top 10 Ways to Get More Durable HMA Pavement fact sheet series are available on the OAPC’s website at, www.onasphalt.org
