Why Pavement Renewal?
The real cost of bad roads:• Rough roads add an average of $335 to the annual cost of
owning a car.• Every $1 spent in keeping a good road good saves spending
$6 to $14 to rebuild one that has deteriorated.

What Do Transportation Agencies Need?
• Innovative ways to speed up the delivery of needed infrastructure improvements at lower costs.
• Guides to build long-life pavements that incorporate the existing pavements into the new pavement structure.
• Rehabilitation projects that lead to more cost-effective results.
• Reusing existing pavement to reduce costs, including
hauling and dumping costs, and to shrink construction. timelines.
• Projects that can be accelerated by reusing existing pavement, alleviating the need to remove and dispose of it offsite.
