  • 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.
