Roadway construction zones are dangerous by their nature. Add in the element of night and suddenly the traditional hazards of roadway work zones are joined with low visibility and a higher rate of impaired or distracted drivers.
Connecting Montreal with Kahnawake, the Honoré Mercier Bridge extends almost one mile over the St. Lawrence River. It serves as a link between Montreal Island and the South Shore, and is the shortest route from Montreal to New York State in the United States. Not surprisingly, it’s one of the busiest bridges in Canada with an estimated 30 million vehicles crossing it each year.
April 30, 2015 - Rock to Road’s first resource roads management maintenance webinar drew approximately 25 attendees interested in learning how to extend the lifetimes of the roads they maintain and build.
There are many reasons why alternatives to salt, or methods for reducing its use, are becoming more popular across Canada.
Feb. 3, 2015 – Topcon has signed an agreement with concrete paving manufacturer GOMACO to provide the 3D control systems for its machines.
In 2012, Vancouver was the first city on the planet to use a wax made from municipal recycled plastic containers in their warm mix asphalt – and paving projects using this new mix continue.
May 13, 2014, Lanham, Md. — As public works agencies and departments of transportation look to make the most efficient use of tight budgets, the National Asphalt Pavement Association is outlining the benefits of Thinlay thin asphalt mixtures for pavement preservation. Thinlays are a suite of thin asphalt overlay mixes designed to be placed at thickness as thin as 5/8 of an inch.

The development of cold mix asphalt has provided a new solution for road and pavement repairs in Canada.
Not too long ago, the milling process was seen as a necessary evil, says Jeff Wiley. Contractors were forced into using it to correct a curb line or scarify a bridge deck.
Among the most exciting new techniques and associated technologies that have been developed in asphalt paving over the last decade is warm mix asphalt (WMA).
In our previous issue, we took a close look at the technologies contributing to the increased use of reclaimed asphalt pavement (RAP) as well as recycled asphalt shingle material.
Like the use of recycled asphalt, use of recycled asphalt shingles (RAS) in paving makes a great deal of sense.
The evolution of recycled asphalt has gone from simply using it as base, to using single sizes back in the hot mix, to fractionating into multiple sizes and treating it similarly to virgin aggregate, notes Patrick Reaver.
