The need for rapid repair and replacement of concrete pavement is evident in every large metropolitan area in the U.S., Canada and other parts of the world. Many aging pavements are exhibiting alarming deterioration as the traffic they are carrying increases to all-time highs. In many locations, pavements must be repaired under traffic because traffic cannot be diverted for any significant length of time. As a result, agencies are forced to rehabilitate roadways with rapid-repair materials that can be installed effectively without adversely affecting traffic flow. Agencies are often forced to choose the cheapest repair material available, even though it may not last more than a few years. A more sustainable approach is to select durable materials that will last for decades, even if the initial costs may be slightly higher. Precast, prestressed concrete pavement systems serve as durable and reliable alternatives to traditional, rapid-repair techniques for concrete pavements.
