Abstract:
Pavement preservation is an approach in enhancing pavement performance using a set of practices that extends the life

of the pavement and improves safety and ride quality. According to the World Bank’s Pavement Deterioration Model, the

cost of returning a pavement to good condition after deterioration may be four times the cost of maintaining it in good

condition (Shahin, 2005). The results of a Utah Department of Transportation (UDOT) research study showed that it costs

less to maintain roads in good condition than in poor condition (Zavitski, et al.). According to the National Cooperative

Highway Research Program (NCHRP) Synthesis 223, every dollar spent on preventative maintenance at the correct time in

a pavement’s life cycle saves $3-4 in future rehabilitation costs (Geoff roy, 1996). Later work by Galehouse, Moulthrop, and

Hicks (2003) showed that future rehabilitation cost savings are $6–10 for every $1 spent on preventative maintenance. Some

surface treatments are eff ective for maintaining pavements in good condition. They are applied to the entire surface of the

pavement and are usually used for pavements with no major structural deterioration. The relatively low cost and simplicity of

these techniques, besides their eff ectiveness in extending the life of the pavement and improving performance, has attracted

many agencies into using them. Chip seal, slurry seal, microsurfacing, surface rejuvenation, fog seal, scrub seal, and thin

overlays are among popular surface treatments.
