MISSISSAUGA, ONT. — The Ontario Asphalt Pavement Council (OAPC) has released all 10 of its Top 10 Lists of hot mix asphalt best practices. The Ways to Get More Durable Hot Mix Asphalt Pavements fact sheets were completed and published this month, stated an Oct. 20 release.
The OAPC developed the Top 10 List series from results of the Quality of Asphalt Review (QAR), which commenced in September 2018. The review was commissioned in the fall of 2017 and was managed by KPMG. It consisted of analysis conducted by the Texas A&M Transportation Institute.
The OAPC is a council of the Ontario Road Builders’ Association.
Topics include: Do Your Homework; Encourage Mixes That Have Higher Asphalt Cement 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; and Complete Quality Assurance Testing and Inspection.
“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, in the release.
