Recycled Aggregate
Recycled concrete aggregate and recycled asphalt aggregate can be used in place of virgin aggregate in a variety of applications. When used in large-scale construction projects, these materials can make a big difference in the overall environmental impact, preserving resources for future generations.
The use of recycled or reclaimed materials in lieu of virgin aggregates is permitted as part of the Ontario Provincial Standard Specifications (OPSS). OPSS 1010 – Base, Subbase, Select Subgrade and Backfill Material – allows for replacement of virgin aggregate up to 100% recycled concrete aggregate (RCA) in Granular A, M, S and B Types I and III material. It also allows for up to 30% recycled asphalt pavement (RAP) – whether that is with virgin aggregate or RCA material. To ensure material performance, Dufferin Aggregates recycled products are tested for compliance of gradation and physical property requirements in accordance with OPSS 1010.
The Ontario Ministry of Transportation (MTO) has been a leader in using recycled material in base, subbase and asphaltic pavements since the 1970’s. MTO also permits the use of recycled aggregates in road granular in 400 series highways in Ontario as base and subbase material. The use of recycled aggregates by the MTO and numerous Ontario municipalities demonstrates the value of recycled aggregates as a viable alternative to virgin materials.

Our Process
At Dufferin Aggregates, we manage a stringent process to ensure our recycled material meet our customers’ expectations. Our processes around receiving and sorting, technical and sales support to ensure appropriate material-to-application matching and robust Quality Management System (QMS) ensure that the recycled material we provide our customers is clean, rigorously tested and used in appropriate applications and mixes to ensure performance and quality.
Certified Aggregate – Cornerstone Standards Council
In February 2016, in a landmark announcement, the Cornerstone Standard’s Council (CSC) officially recognized CRH Canada’s Dufferin Aggregates Acton Quarry as the first quarry in the world to receive certification as a supplier of responsibly sourced stone, sand and gravel. The CSC is a non-profit organization focused on engaging industry and community stakeholders in the on-the-ground application of its Responsible Aggregate Standard in order to build a market for certified aggregate materials.
The seven principles that are the foundation for the Cornerstone certification are consistent with the way Dufferin Aggregates has operated its sites for many years, and we believe, an important mechanism towards ensuring a sustainable future.
CRH Canada and Dufferin Aggregates are extremely proud to have received the first certification and hope that this achievement will be a catalyst for the industry. This certification is a testament to our commitment to address the demand for aggregates that consider community and environmental needs. Now any purchaser of aggregates, be it the public or the private sector, will have the confidence in knowing that they are buying responsibly sourced building material.
CRH Canada in partnership with Environmental Defense is proud to have been among the founding members of the organization.
