“…A considerable amount of literature about preventive maintenance treatment analysis has been published, and these studies investigated the effectiveness, cost, influencing factors, etc. of the PM treatments [2,9,14,19,20]. These studies have revealed that different PM treatments varied on addressing different distresses for pavements, and the most effective treatment was not always the most cost-effective treatment.…”

“…Therefore, this study employed the short-term pavement performance in terms of longitudinal cracking, transverse cracking, alligator cracking, roughness, and rutting as indicators to evaluate the effectiveness of the PM treatments. These research results have revealed that thin overlay is the most effective PM treatment, followed by chip seal, and slurry seal [2,11,19]. In contrast, crack seal does not have as good long-term effectiveness as the other PM treatments [2,20].…”

“…Preventive maintenance (PM) is one of the primary components in any pavement preservation program, and is typically applied to pavements when the pavements are still in relatively good condition with a significant amount of remaining service life. A PM applies cost-effective treatments to the surface or near-surface of structurally sound pavements, and mainly serves to prolong the pavement life by alleviating pavement functional deterioration without the requirement of enhancing pavement structure [2]. Currently, various PM treatments have been employed by highway transportation agencies to restore pavement serviceability and retard future deterioration [3].…”

“…Actually, differences in effectiveness of PM treatments could be caused by many influential factors, such as traffic, climate in construction, and structure [2,6,19,21,22]. The ASTM special technical publication (STP-1348) required that the PM treatment selected for a section of pavement should consider the condition of the existing pavement, the traffic volumes using the pavement, and the environmental conditions [23].…”

Preventive maintenance (PM) has been a pavement asset management strategy widely used by many highway agencies to improve pavement conditions, restore pavement serviceability, retard deterioration, and prolong pavement life. Practical experience shows that the effectiveness of different kinds of PM treatments varies for different distresses in short-term pavement performance which is related to the long-term pavement performance. The objective of this study is to evaluate the effectiveness of PM treatments in short-term asphalt pavement performance using the Specific Pavement Studies (SPS-3) data of the Long-Term Pavement Performance (LTPP) Program. The PM treatments included in the study were chip seal, crack seal, slurry seal, and thin overlay, and the related SPS-3 data were retrieved from LTPP for the study. Longitudinal cracking, transverse cracking, alligator cracking, roughness, and rutting were employed as indicators to evaluate possible pavement performance improvements. Statistical methods were applied to compare the effectiveness of PM treatments in terms of the performance indicators of longitudinal cracking, transverse cracking, alligator cracking, roughness, and rutting. In addition, mixed-effects logistic regression was conducted to find the significant influential factors and quantify the influence of various factors such as temperature, precipitation, cloud cover, subgrade material, truck traffic, and asphalt concrete layer thickness on the improvements of pavement performance. The analysis results showed that chip seal and thin overlay have most significant effects on short-term cracking improvements. Thin overlay has the best effect on short-term roughness and rutting improvements. As of influential factors, temperature, cloud cover, and subgrade material are significantly important factors in PM treatments. These results may provide performance data enabled understanding of the effectiveness of PM treatments.
