The September 2020 pavement study.
Authored by Hassan Baaj, Pejoohan Tavassoti, Goretty Dias and Giancarlo Lorena, the InnovAct Consulting study compares flexible pavement systems: a conventional reference, lightweight concrete alternatives and an XPS-panel alternative. Often referred to as the “Waterloo study”, the report identifies InnovAct Consulting as its institutional author.
