Research and Development

Since the beginning, we have been involved in practical research and development. We carried out work on some of the first crumb rubber and shingle mix trials conducted in the early 90’s. DBA was also extensively involved in the first Superpave project in Ontario, the LTPP SPS-9A project in Petawawa, on behalf on the MTO. We were one of the first labs to have the Superpave Gyratory Compactor and the PGAC SHRP asphalt cement testing equipment.

We have also been involved in some of the key SMA projects and have conducted research on the new MTO low temperature tests being currently evaluated in Ontario.

We continue to get involved in research work and just recently committed funds to sponsor the new Norman W. McLeod Chair in Sustainable Pavement at the University of Waterloo’s Centre for Pavement and Technology Transfer (CPATT).
