GIVING BACK THROUGH R&D
08 - Continued Partnership With Concordia University
09 - Additional Research with Queen’s University Titan continued the NSERC collaborative research and development grant project with Queen’s University to evaluate the performance of bituminous geomembrane (BGM) in mining applications. More research was conducted this year to evaluate the seam quality and ageing strength of BGM seams in comparison to those of conventional HDPE geomembranes. The research also examined the leakage characteristics of BGM and investigated accelerated ageing techniques. The chemical durability of BGM was tested in four different solutions of varying pH values. The conclusions were promising and will be presented in a technical paper in 2019. 10 - Fied Testing New High Performance Fiberglass Geogrid Another leap with Titan geogrid innovation in 2018 involved the development of a high-performance fiberglass geogrid for asphalt reinforcement—(TE-FGP11-EPM). This new geogrid is polymer coated and bonded to an engineered polymeric membrane (EPM) to facilitate stronger adhesion to the asphalt layers. The grid is placed with the EMP side facing up to be paved over. TE-FGP11-EPM fiberglass geogrid was field tested with the City of Calgary and the City of Winnipeg as part of some pavement rehabilitation projects. We are thrilled to report that the EPM layer fully melted upon paving resulting in strong bonding strength of the geogrid within the asphalt layers.
We continued to work with Montreal’s Concordia University thanks to a two-year grant from the Natural Sciences and Engineering Research Council of Canada (NSERC), through the Collaborative Research Development program (CRD). Our research continued to focus on improving surface water quality using custom developed geotextiles. Building on previous experiments we monitored the use of nonwoven geotextiles with different opening sizes and thicknesses for filtration of lake water. In-situ filtration tests were conducted and presented clogging challenges. These challenges were overcome by using a custom made hybrid combination of woven and nonwoven geotextiles with controlled opening sizes. We hope to present a technical research paper detailing the findings of this study at a conference in Toronto in June, 2019.
