TEMPLATE Letter for Members to Use to Submit Responses to ERO Posting on Growth Plan February 13, 2019
The government has submitted a proposal to make Modifications to O. Reg. 311/06 (Transitional Matters - Growth Plans) made under the Places to Grow Act, 2005 to implement the Proposed Amendment to the Growth Plan for the Greater Golden Horseshoe, 2017. OSSGA has made the point to the government that the current policy framework is not working. Approvals for new mineral aggregate operations in Southern Ontario are taking up to 10 years to complete the process. There are too many overlapping policies and inconsistent approaches between the Provincial Plans, Regional Official Plans, Local Official Plans and Conservation Authority policies regarding the management of this essential non-renewable resource.

‘Road Tour’ ignites lively discussion on quality of pavements

May 9, 2014

Nearly 150 industry experts took part in the Ontario Hot Mix Producers Association’s (OHMPA’s) ‘Road Tour’ seminars which concluded on May 6th in Mississauga. The initiative, which brought together asphalt producers, suppliers, consulting engineers and municipal and provincial road owners, was a tremendous success according to Doug Duke, OHMPA Executive Director. 
“We had terrific representation from all sectors throughout most of Ontario’s regions as we made stops in Guelph, Kingston, Sudbury and the GTA,” said Mr. Duke. “This year’s seminars stimulated some very engaging conversation, especially in Kingston where Queens University Professor Simon Hesp attended our roundtable discussion regarding the quality of asphalt cement.”
“Our primary mission is to promote excellence in asphalt paving. At the end of the day, we share the same goals as road owners and researchers alike. That is, to have the best roads in North America.  Bringing together all stakeholders in the same room is the first step in ensuring we continue to improve Ontario’s road quality.”
OHMPA’s Technical Director Sandy Brown addressed the hot topic of 2014 – potholes. “It’s been a spectacular winter,” said Mr. Brown. “We’ve had polar vortexes, flash freezes, thunder snow; things I had never heard of before. It has taken a toll on the pavements. However, when it comes to preventing potholes, it all starts with the design of the pavement, ensuring proper drainage and the thickness of the pavement lift is crucial.”
Mr. Brown also captured the attention of the audience with his demonstration using two-by-four planks of pine.  Pressing down on the wood, he demonstrated that it bends significantly, until the wood is turned on its side to make it thicker.  Additionally, bringing out another wood sample glued together, he showed that the same principal applies to using tack coat to strengthen pavements. 
“I could have purchased a solid oak two-by-four, but just one cost six times more than four pine planks,” explained Mr. Brown. “The molecular structure of the oak is stronger than the pine, but I can get the same strength by having a thicker piece of pine or gluing two together.  The same goes for asphalt cement.  Contrary to current hyperbole, there is no garbage in Ontario’s asphalt cement and one way to improve the quality of pavements in a cost effective manner, is to have thicker lifts and use tack coat.”
Other highlights from the seminars included MTO regional reports and updates on provincial initiatives, the introduction of the Draft Contract Language on the MGAC specification addressing asphalt cement quality, municipal presentations on best practices for improving longitudinal joints and an update on OHMPA’s new and upcoming marketing and communications initiatives.
