While overlays are widely used, they are not always targeted. Targeted overlay pavement solutions, or TOPS, uses different overlays for different locations where they can get the biggest bang for your buck. Targeted means the selection and intentional use of the most effective, enhanced, and longer-lasting method.
In the United States, there is a huge gap between available funding and needed funding for highways and bridges. There is also a significant portion of roadways that are in poor or mediocre condition. Those deteriorated roadways have real impacts on the users of the transportation system.
Many of the pavements in the Nation's highway system have reached or are approaching the end of their design life. These roadways still carry daily traffic that often far exceeds their initial design criteria. Overlays are now available for both asphalt and concrete pavements that enable agencies to provide long-life performance under a wide range of traffic, environmental, and existing pavement conditions. This is where TOPS come in.
TOPS integrate innovative asphalt and concrete overlay procedures into practices that can improve performance, lessen traffic impacts, and reduce the cost of pavement ownership.
