This book was released on 2013 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Long-Term Pavement Performance (LTPP) Program Specific Pavement Studies (SPS) written by Gonzalo R. Rada and published by . This book was released on 2018 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pavement preservation represents a proactive approach to maintaining and extending the lives of existing highway pavements. At the heart of the preservation decision-making process is pavement performance. This report documents the recommended experimental design for the LTPP SPS-11 Asphalt Concrete (AC) Pavement Preservation Study as well as the various elements required for its successful implementation. However, the recommended experiment will not be implemented under the LTPP program, but the experiment and this project report can be adopted and adapted by interested highway agencies to achieve the stated benefits, and consequently the impetus for publication of the report. The underlying concept of the experiment is to apply the same preservation treatment, at different times, on the same pavement structure to determine the effectiveness of a single application of a treatment as a function of pavement condition and time. This experiment is designed to answer the question on when is the best time to apply a preservation treatment on AC pavements. It will also enable development and implementation of important pavement preservation products and tools, such as addition of pavement preservation considerations to the AASHTO Mechanistic-Empirical Pavement Design Guide and associated software.

Book excerpt: 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.

Download or read book Pavement Maintenance Effectiveness written by Roger Smith and published by Strategic Highway Research Program (Shrp). This book was released on 1993 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study evaluated 6 specific preventive treatments. Four treatments are for asphalt concrete surfaced (flexible) pavements: chip seals; crack sealing; slurry seals; and thin overlays. Two treatments are for portland cement concrete surfaced pavements: joint and crack sealing; and undersealing. Performance of the pavement sections with the treatments was compared with the performance of a similar pavement section without the treatment. Performance is measured in terms of pavement distress, roughness profile, surface friction, and structural capacity. All of the flexible pavement test sections and most of the rigid pavement test sections have been constructed. Performance data are being collected. This report discusses the experimental design, project selection, construction, data collection, analysis, and future activities of the pavement maintenance effectiveness project.

Book Synopsis A Methodology for Developing Performance-Related Specifications for Pavement Preservation Treatments by : Litao Liu
Download or read book A Methodology for Developing Performance-Related Specifications for Pavement Preservation Treatments written by Litao Liu and published by . This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Current materials and construction specifications for pavement preservation treatments are predominantly prescriptive and they have little or no methodical linkage between initial treatment quality and future performance. There is an imperative need for performance-related specifications (PRS) that link the initial quality of pavement preservation treatments to their long-term performance and life-cycle costs so that rational pay adjustment and acceptance decisions can be made. However, the current literature lacks a methodology for developing PRS for pavement preservation treatments. The aim of this research is to fill this gap in the literature, with focus on thin HMA overlays. In this dissertation, a novel approach was devised for developing performance prediction models for pavements that received preservation treatments. In this approach, the model consists of two tightly-coupled components: the first component is responsible for predicting the performance (e.g., IRI) of the existing pavement if no treatment was applied. The second component is responsible for predicting the reduction in pavement deterioration due to the application of the treatment. Inputs to the first component include material and construction properties of the existing pavement layers, climatic conditions, and traffic factors. Inputs to the second component include the treatment's acceptance quality characteristics (AQCs), climatic conditions, and traffic factors. The artificial neural networks (ANNs) and the Bayesian regression methods were used for developing the two model components. Using this approach, a model was developed for predicting the International Roughness Index (IRI) of flexible pavement treated with thin HMA overlay. The data used for developing and testing this model was obtained from the Long-Term Pavement Performance (LTPP) database. Artificial neural networks (ANNs) and Bayesian regression techniques were employed for developing the first and second components of this model, respectively. A PRS methodology was developed for quantifying the difference between the initial quality levels of as-constructed and as-designed treatments. This methodology consists of a novel approach for determining the probability distributions of service life and present-worth value (PWV). This approach allows for transforming the probabilistic distribution of future IRI (predicted by the Bayesian model) into probability distributions for service life and PWV. Pay factors are then estimated based on the difference between the as-constructed and target PWVs. Finally, this dissertation provides insights into the relationships between initial quality (measured in terms of both mean and standard deviation of key acceptance quality characteristics) and expected pay factors through analysis of real world case studies of asphalt pavements treated with thin HMA overlays.
