2019 Spring Meeting Highlights

The Chief Engineers’ Council met in Ottawa on Saturday, April 6 and Sunday, April 7. The Council received presentations on the Vision Zero movement in Canada, the City of Toronto’s work to mitigate threats from hostile vehicles, a survey of Council members on alternative procurement practices, and a completed project on transportation and health by the Urban Transportation Council. It also received final presentations on two Chief Engineers’ Council projects: Best Practices for Pothole Repairs in Canada, and a new Special Roads chapter in the Geometric Design Guide for Canadian Roads, both of which will proceed to approval by ballot.

The Council’s regular roundtable discussion focused primarily on climate change, and identified a number of emerging and priority issues including rainfall and drainage impacts on infrastructure and land uses, freeze-thaw impacts on roadways, deteriorating asphalt quality, storm impacts on coastal erosion and infrastructure, municipal resiliency staffing and strategies, and assessing the impacts of projects on greenhouse gas emissions.

The Council also received updates from eight standing committees, summarized below.

The Traffic Operations and Management Standing Committee reported that the recent volunteer project on decorative crosswalks will be converted to a pooled-fund study. New volunteer projects will address crossrides at right-turn channels, active mode symbols, and active mode signal timing.

The Structures Standing Committee reported on several presentations, and noted emerging issues with steel bridges including globally-sourced material standards and training for bridge fabrication inspectors.

The Soils and Materials Standing Committee reported on presentations addressing Portland limestone cement, warm-mix asphalt and hot-mix asphalt, and noted emerging issues include drone use, asphalt binders, climate change, and 3-D printing.

The Road Safety Standing Committee reported its adoption of a new three-year strategic plan, and discussions about street lighting, Vision Zero, legislative changes, and roadside barriers. It also highlighted a proposed pooled-fund project to develop a road safety webinar series.

The Pavements Standing Committee noted that it received presentations on ground penetrating radar, Iqaluit airport construction, fibre in asphalt mixes, and permeable pavers. It reported a new volunteer project on benchmarking agency pavement performance measures, and progress on a pooled-fund project proposal on consistency and performance measures when systems for pavement condition data collection are upgraded.

The Maintenance and Construction Standing Committee reported that it heard a presentation on 2018 flooding in New Brunswick, and that emerging issues include cannabis and fitness for work, and the management of pilots, offers, trials and sales in large agencies. The committee has a number of volunteer and pooled-fund projects underway.

The Geometric Design Standing Committee reported volunteer work to update Geometric Design Guide for Canadian Roads chapters on interchanges, cross-section elements, and access management. It also noted that a new chapter on special roads is ready for approval by the Chief Engineers’ Council.

The Asset Management Task Force reported that it heard a presentation on pavement marking reflectivity, and discussed best practices for asset data collection. It noted growing interest in the integration of climate-resilient infrastructure and asset management, particularly for drainage (i.e. culverts and bridges). It also noted approval of a new pooled-fund project on location referencing in asset management.

TAC Awards

At its April meeting, the Chief Engineers’ Council approved the following awards for presentation at the 2019 TAC-ITS Canada Joint Conference in Halifax.

2019 TAC Individual Contribution Award
Ania Anthony (Saskatchewan Ministry of Highways & Infrastructure) has been on the Executive of the Soils and Materials Standing Committee since 2013. She is also a member of the Pavements Standing Committee, where she co-authored a report on the impacts of Wide Base Single Tires on pavements. Ania has chaired the Project Steering Committees for Best Practices for Evaluating Soil and Material Stabilization Products, and the Guide to Load Management for Weak Pavement Structures. She is a trusted voice within TAC, representing the Saskatchewan perspective and investing her time and expertise in national conversations on pavements and road materials.

2019 TAC Road Safety Engineering Award
The City of Calgary uses Traffic Calming Curbs (TC Curbs) to traffic calm streets quickly, at a low cost. Pre-cast TC Curbs can physically alter a space in hours without impacting utilities or drainage, at one tenth the cost of conventional traffic calming methods. TC Curbs are modular and easily adjusted, can be pinned to the pavement, are reinforced to be driven over, and use pigmented and sulphate-resistant cement for durability. They are a useful tool to encourage safer road use by changing the road environment.

2019 TAC Committee Excellence Award
The Road Safety Workforce Subcommittee played a key role in the development of the Road Safety Professional certification program by the Transportation Professional Certification Board. It has also researched road safety programs at Canadian universities and colleges, compiled educational and training resources, scanned organizational training practices, and developed a detailed pooled-fund project proposal for a webinar series that would provide comprehensive road safety training to practitioners.

Publications Coming Soon

Three new publications arising from the work of the Chief Engineers’ Council will be available soon through the online Bookstore. Notices will be posted online when they are published. Get more information

Best Practices for Pothole Repairs in Canada
This report will identify current Canadian agency practices for pothole repair, and outline best practices from both Canadian and international agencies. It recommends temporary and long-term patching strategies for summer and winter, and for evaluating and selecting appropriate patching products for chip seal and asphalt roadways. It also recommends guidelines for the evaluation of new patching products and their compatibility with native road surfaces. It resulted from a pooled-fund project of the Soils and Materials Standing Committee.

Special Roads – Chapter 11, Geometric Design Guide for Canadian Roads
This chapter will include a classification of special roads to meet the special service requirements of road agencies across Canada. It provides guidelines that support safe and effective road function and ensure standardization while being compatible with present economic requirements. It was developed by volunteers of the Geometric Design Standing Committee.
