May 12, 2014, Surrey, B.C. – Mainroad Pavement Marking announces the use of a new and innovative retroreflectivity technology by Zehntner Testing Instruments.
For 25 years, Dicrete’s curbing work for new housing developments was labour intensive, and required personnel on each crew to string the lines to ensure the concrete was laid accurately.
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.
Although winter takes a toll on many industries, one of the hardest hit is roadbuilding and paving repair.
To the average driver on Ontario’s Highway 12, this summer’s paving job looked like any other paving project, and was nothing more than a mild inconvenience.
If you have driven anywhere in British Columbia lately, you have probably rolled over pavement that has been recycled by Green Roads Recycling Ltd. using the hot-in-place (HIP) recycling process.
The concept is simple enough. By placing and compacting at screed two layers of hot mix asphalt – binder and surface – in one continuous and simultaneous process, a more durable, bonded road surface is created.
As its moniker suggests, EZ Street can make life a breeze for roadbuilding and repair crews. The name also accurately defines why the product is already being used in 20 countries and is quickly gaining traction in Canada since the launch of EZ Street Canada three years ago in Yellowknife.
Concrete overlays, formerly known as whitetopping, inlays and ultra-thin whitetopping, are just what the name suggests – laying concrete over asphalt, composite or old concrete pavements for environmentally friendly, long-lasting and cost-effective rehabilitation.
Road foundation design and construction will probably never be a hot topic of conversation among users of Canada’s road network, even though many of us benefit from the results every day.
