This document is a technical summary of the Federal Highway Administration report, Impact of Design Features on Pavement Response and Performance in Rehabilitated Flexible and Rigid Pavements (FHWA-HRT-10-066). Rehabilitation and pavement preservation represent the majority of pavement construction activity in the United States. Preventive maintenance includes treatments that are applied to pavements primarily to delay development of and mitigate existing distresses. These treatments focus on improving pavement functional performance and prolonging pavement life, not on improving the structural capacity. Selecting the appropriate maintenance technique and treatment application timing form the basis of a preventive maintenance practice. In addition to a nontreated control section, the Specific Pavement Study (SPS)-3 experiment included the following four maintenance treatment alternatives: Thin hot mix asphalt overlay (typically 1 inch (25.4 mm) or less). Slurry seal. Crack seal. Chip seal. Additionally, each site was categorized according to the following five design factors: Moisture (wet or dry climate). Temperature (freeze or no-freeze zone). Subgrade type (fine grained or coarse grained). Traffic loading (low or high). Existing pavement condition (good, fair, or poor). This experimental design resulted in 48 different experimental combinations of factors. In total, 33 States and Canadian Provinces participated in the experiment, and 81 sites were constructed and monitored for the assessment.

Pavement preservation can retard the development of pavement distresses and improve pavement functional performance. Quantification of the effectiveness of preservation has important implications for the selection of pavement maintenance strategies and decision making in pavement management system. Most of previous studies mainly focused on the effectiveness of preservation on pavement serviceability index (PCI) and roughness; few studies considered the effectiveness of preservation on individual pavement distresses and pavement surface friction. The objective of this thesis is to investigate the effectiveness of pavement preservation on mitigating multiple pavement distresses and restoring pavement surface friction. The datasets are selected from the Specific Pavement Studis-3 (SPS) experiments of the Long Term Pavement Performance (LTPP) program. The SPS-3 includes the performance of four preservation treatments (thin overlay, chip seal, crack seal, and slurry seal) under five design factors (traffic, temperature, precipitation, existing pavement condition, and subgrade type). The pavement distresses considered in the analysis include fatigue cracking, longitudinal cracking, transverse cracking, and rutting. The effectiveness of pavement preservation is quantified using the distress area ratio, which is associated with the areas under the distress curves after treatments and the distress curves with do-nothing. Statistical tests were used to compare the effectiveness of preservation treatments and identify the significant factors that affect the effectiveness of preservation. Results show that chip seals have little effectiveness in rutting prevention; slurry seals demonstrate effectiveness in longitudinal cracking; crack seals show effectiveness in fatigue cracking. On the other hand, the effectiveness of preservation treatments on pavement surface friction and the long-term variation of friction were investigated. The results of statistical analysis indicate that slurry seal causes significantly greater friction number compared to the control section. Stepwise regression analysis was conducted to quantify the influence of various factors on the long-term variation of pavement friction. The precipitation, freeze index, and pavement roughness showed significant correlation to the friction number in the regression models. The analysis results can aid state pavement agencies better select the appropriate maintenance treatments based on the existing pavement condition to maximize the effectiveness of preservation treatment.

The primary focus of this research was to determine the effects of design and construction features, such as overlay thickness and mix type, presence of milling, and type of restoration, on pavement response and performance and to establish their importance in the prediction of future performances of rehabilitated pavements. Long-Term Pavement Performance program Specific Pavement Study (SPS)-5 and SPS-6 experiments provided information to obtain a better understanding of the effects of design and construction features on pavement response and performance of rehabilitated flexible and rigid pavements.
