Urban Application of Perpetual Pavements - Case Study from BRT in York Region

Conventional asphalt pavement is typically designed for a 20-year life expectancy. The concept of extending the life well beyond this period mainly on high volume roads is gaining acceptance in Canada. Long life pavements, also called perpetual pavements, have been used on a few projects in Ontario during recent years. However, the use of perpetual pavement has been limited to highways. This paper discusses the use of perpetual pavement in urban environments and the transition of this technology from highway applications to urban roadways. It presents the challenges and how to overcome them. The challenges of the urban environment that are not typically associated with highways include the presence of utilities, frequent intersections, bus traffic, frequent widenings, construction staging, and elevation restrictions. The benefits of using perpetual pavement in urban environments are also described. A case study included in this paper demonstrates a practical application of perpetual pavement in urban environments. A Bus Rapid Transit (BRT) system is being developed in York Region and perpetual pavement has been designed for much of the BRT length in this project. The experience of designing perpetual pavement as a rehabilitation method and new construction solution is presented. (A)
