Available in PDF, EPUB and Kindle. Book excerpt: As an alternative to traditional contracting, pavement warranty has been adopted in Mississippi since 2000, aimed to enhance pavement performance and protect the investment in pavement construction. Currently, a manual distress survey method and the associated deduct point-based pavement condition rating approach are employed to monitor the performance of warranty pavements (maintained projects). The main objective of this study is to evaluate the appropriateness of using the current deduct points distress thresholds to monitor the performance of the maintained projects in Mississippi. In the study, a comprehensive literature review and online survey were conducted to review the recent state of practice of pavement warranty in North America. The analytical section of the study employed pavement distress and riding quality data collected form warranty pavements and the corresponding data of non-warranty pavements stored in MDOT's Pavement Management System (PMS) for the statistical analysis. Using raw data, converted deduct points, and composite index as performance indicators, basic statistics were developed to investigate the distribution of performance indicators at various service times and the corresponding percentiles associated with the existing threshold values. In addition, pairwise comparisons were conducted to examine the evolvement of distress over time for warranted and non-warranted pavements. Further, two sample t-tests were performed to compare the performance of warranted and non-warranted pavements at the same service time. The survey study has shown that most other pavement warranty programs in other states use direct measurements of pavement distresses or densities of pavement distresses for their distress indicators and thresholds while the pavement warranty program at MDOT employs deduct points based distress thresholds which are quantities converted from measurements of pavement distresses. The analytical results show that the performance of warranty pavements is significantly better than that of non-warranty pavements at the same service time level, and warranty pavements can maintain at high service levels for a longer time than non-warranty pavements. The pavement warranty program adopted by MDOT has improved pavement performance, and is effective in practice. However, the current distress thresholds adopted by MDOT are inconsistent with regard to the various corresponding percentile levels for different distress types at a same service time, and the different increase rates of the percentile level for different distress types over service time. It is suggested that direct measurements of pavement distresses or distress densities be used as distress thresholds, and consistent threshold levels be implemented for all distress types.

This book was released on 1989 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: This manual categorizes distress manifestations and provides illustrations of each category to lend uniformity to reporting and interpretation. Descriptions of the density of occurrence and the severity of each type of distress manifestation are made to conform to standard words which precisely express the relative density or severity on a scale of 1-5. Probable causes of each distress manifestation are presented, together with comments on progressive deterioration or other behaviour which might affect remedial treatment. Possible remedial measures are included under each distress manifestation.

Available in PDF, EPUB and Kindle. Book excerpt: This report documents the second phase of an FHWA study, entitled "Pavement Condition Monitoring Methods and Equipment". In this phase selected distress survey methods and devices, representing a range in automation, were tested from July to September 1986. The following methods and devices were included in the testing: manual mapping, detailed visual surveys using manual recording and automatic data logging, PASCO ROADRECON survey vehicle, the GERPHO survey vehicle, the ARAN survey vehicle, and the Laser RST survey vehicle. The field tests were conducted on flexible, rigid, and composite pavements exhibiting a range of pavement distresses. The survey devices were evaluated using performance, capability, efficiency, and cost-effectiveness criteria.

Book excerpt: Pavement Distress rating is a critical factor in analyzing the performance of road pavement surfaces. A commonly used pavement distress rating program is the Strategic Highway Research Program (SHRP) developed by the US Federal Highway Administration (FHWA). The SHRP distress rating manual establishes standards which rate pavement cracking and categorizes them as to type, severity and extent. This information is frequently used as input to database systems for Pavement Management Systems. Human visual observation and rating of pavement distress, such as cracking, is subjective and unreliable for analysis of pavement performance over time. New technology advances in video recording and computer processing of digital images, offers a high speed objective method that is reliable and repeatable, for automated distress analysis. This paper describes WiseCrax(r) which is one such method of automated distress analysis developed by Roadware Corporation that employs digital, non-interlaced video cameras to record high quality pavement video images. The process is divided into three separate steps: data acquisition; crack detection; and crack class ification (alligator or fatigue, block, longitudinal, etc.). This modular approach provides a high degree of flexibility to accommodate changes and improvements in new hardware and software. It also allows WiseCrax to be used with a wide range of class ification schemes including the Universal Crack Indicator (UCI) protocol developed by the World Bank. The technology was tested in several FHWA sponsored tests in the past three years. It has now left the laboratory phase and is being implemented in several large infrastructure projects in the United States. Additional enhancements are being planned to improve all stages of the process from better data acquisition to crack class ification algorithms based on neural network and artificial intelligence programs developed for the US Defense Industry. For the covering abstract of this conference see IRRD number 872978.
