The Bruce Hwy – Six Mile Creek to Gavial Creek Pavement Widening and Rehabilitation Project stands as a comprehensive endeavour, addressing the widening and rehabilitation needs of over 12km of the Bruce Hwy. The project entails the construction of a Foamed Bitumen in situ stabilized base over a triple blend stabilized subbase, strategically optimizing the use of existing pavement and subgrade materials. Faced with the challenge of dealing with weakened subgrades saturated from the 2017 flood, the project team astutely recognized the constructability issues tied to the waterlogged subgrade. To surmount this obstacle, the team introduced an innovative solution: employing lime to treat the subgrade without exposing it, eliminating the need for conventional lime stabilization that typically requires subgrade exposure. This inventive technique not only effectively resolved the saturated subgrade issue but also yielded substantial cost savings during project execution. The success of this approach gained acclaim, prompting E & T Pavement Rehabilitation to adopt it statewide, highlighting its efficacy in overcoming subgrade challenges across diverse projects.
