Abstract:
It is no secret that all levels of government are facing an unprecedented level of defi cit.

While revenues are dropping, infrastructure needs are growing with age. The question of

sustainability is taking the center stage. Can we aff ord to keep 3 million miles of paved

roads in the United States? Pavements must be managed, not just maintained. That

means fi nding the most cost-eff ective way.

The World Bank’s Pavement Deterioration Model shows that, if a pavement is left to

deteriorate, the cost of bringing it back to good condition may be four times the cost

of maintaining it at a good/fair condition. Preventative maintenance is one of the most

popular ways of managing roadway pavements.

Surface treatments fall under “Preventive Maintenance,” which is generally applied to

pavements in good condition and without much structural deterioration. Many types of

surface treatments are available, including slurry seal, chip seal, micro surfacing, surface

rejuvenation, fog seal, and newer types containing cement, polymer, rubber, or other

agents. The relatively low cost and simplicity of application helps more agencies use

them, especially in times of a low budget. The question is: are road agencies getting

their money’s worth on surface treatments?

The research conducted under this proposal will examine the state of practice in the

United States, particularly the southeast region, with respect to pavement surface

treatments. This synthesis study will summarize the results of surface treatment

research completed to date, as well as state best practices and implementation status.

Findings from this study should be a good reference for agencies that use or intend

to use surface treatments, providing useful information on elements such as types of

applications, best practices, cost, and documented performance.
