10 years of concrete pavement maintenance innovation to extend service life

The Highway 407 Express Toll Route (ETR) concession in Ontario, Canada is responsible for the management of a large highway network for a period of 99 years. As a part of that concession, 407 ETR manages over 600 lane-kilometres of exposed concrete highway. 407 ETR has a very active pavement maintenance and preservation program to maximize the life of the pavement. Also, as a private sector concession, they have the ability to act quickly and actively partner with industry to promote innovation. 407 ETR has a very active pavement management and maintenance management system that is used for future needs planning but more importantly is used to identify maintenance and rehabilitation needs early in their development so that they can be addressed using a less expensive preventive maintenance program. It is in the best interest of the concession to maximize the life of the pavement and to provide a very high quality riding surface for the paying public and to avoid disruptions to traffic flow and revenue. To accomplish this, 407 ETR has employed many maintenance techniques including: slab stitching, dowel bar retrofit, joint retrofit, diamond grinding, shot blasting, longitudinal grooving, underslab sealing and lifting, targeted slab replacement, micro-surfacing and other proprietary thin asphalt surfaces. This paper reviews each of the concrete pavement maintenance and repair techniques used by 407 ETR over the past 10 years, discusses their performance and provides guidance on “what to do and what not to do” aspects of their use and compares their lifecycle benefits.
