only on isolated special projects. This new way of doing business is built on more collaborative relationships and decision making; better integration of management, planning, design, construction, and maintenance; and more synergistic use of technologies and methods so that optimal benefits can be realized from complementary sets of innovations.
The benefits of rapid renewal are many. The most immediate benefit is reduced disruption for users of the roadway, as well as adjacent businesses and property owners. This benefit can be realized through avoidance of delays from construction, a decrease in the time a facility may experience reduced capacity or local businesses may be inconvenienced, and less construction noise for adjacent businesses and property owners. Less delay for trucks means reduced freight transportation costs and overall benefits to the economy. In addition, more collaborative decision making may contribute to streamlined project delivery. Performance specifications and nondestructive testing reduce the number of people required to ensure high-quality results; resources previously devoted to quality verification can be redirected to building and maintenance. Smoother pavements promote fuel efficiency (Amos 2006) and reduce noise (Wayson 1998). Renewal using recycled materials benefits the environment by avoiding the additional energy consumption associated with the production of new materials. Shorter construction times reduce exposure to work zone crashes, which killed more than 1,000 people in 2005 and injure more than 40,000 each year (FHWA 2007b). In the long run, the largest benefit will come from an increase in the life of highway assets. Bridges and roads that last longer mean billions of taxpayer dollars saved, as well as less frequent disruption from future renewal activities.
Renewal time in the field can be defined as the time it takes to complete those on-roadway construction activities that affect traffic flow and the communities and businesses that rely on the roadway for services. Rapid renewal applies innovative approaches or technologies to reduce the time traditionally allocated to these on-roadway activities, thereby minimizing
