Book excerpt: "State departments of transportation (DOTs), as part of their routine practice, use various quality assurance (QA) procedures in their acceptance process for highway pavement construction. Absent from this QA process is the use of nondestructive testing (NDT) methods, despite their many potential benefits to the process. [This report] is a manual designed to assist state DOTs in selecting and incorporating applicable NDT methods into their QA programs for highway pavement construction." -- publisher's website

This book was released on 2020 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: Highway systems contribute immensely to economic development and growth. However, the recent D+ rating for highway infrastructure in the US highlights the dire state of highways across the nation and the need to invest in renovating or building new roads. The cascading impact of regular highway projects creates a need to construct highways that will last longer. The adverse effect of these operations increases the economic cost for state highway agencies (SHA) and commuters. For example, congestion costs for the freight industry in 2018 exceeded $87 billion. Efficient and sustainable construction practices can increase the return on investment and provide the infrastructure that meets and possibly exceeds the design life. With respect to pavements, asphalt concrete (AC) comprises over 90% of pavement surface materials. A well-designed AC pavement can have a lifespan of over 15 years with minor maintenance; however, this design life may be reduced without strongly enforced quality management processes (i.e. quality control (QC) and quality assurance (QA) programs). In cases of exceptional QC/QA programs, SHAs have observed long AC pavement service lives. For example, there is a section of I-90 in Washington state that has been in service for 35 years with no rehabilitation except minor resurfacing. The New Jersey DOT found the same to be true on a section of I-287 with 26-year-old AC pavement. This dissertation focuses on the quality of highway construction in these aspects: 1. Effect of nighttime construction on quality of asphalt paving, 2. A review of the application of emerging technologies for highway construction quality management, 3. Quality management technologies in highway construction: stakeholders' perception of utility, benefits, and barriers, 4. Model development for automation assessment readiness in highway construction quality management processes: a fuzzy synthetic evaluation approach. Existing literature for pavement construction practices and operations have primarily focused on cost, schedule, and safety whereas this study will examine the issues surrounding quality during construction in the context of paving operation technology and efficiency. Similarly, existing literature for pavement construction practices contains numerous studies evaluating nondestructive testing NDT technology. However, this study will evaluate the application of various technologies holistically to identify information on the current state, effectiveness, and automation readiness of some quality management technologies in the highway construction industry. Information from the study will enhance the adoption of emerging methods for quality management processes and procedures in highway construction.

This book was released on 2015 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: Asphalt pavements suffer various failures due to insufficient quality within their design lives. The American Association of State Highway and Transportation Officials (AASHTO) Mechanistic-Empirical Pavement Design Guide (MEPDG) has been proposed to improve pavement quality through quantitative performance prediction. Evaluation of the actual performance (quality) of pavements requires in situ nondestructive testing (NDT) techniques that can accurately measure the most critical, objective, and sensitive properties of pavement systems. The purpose of this study is to assess existing as well as promising new NDT technologies for quality control/quality assurance (QC/QA) of asphalt mixtures. Specifically, this study examined field measurements of density via the PaveTracker electromagnetic gage, shear-wave velocity via surface-wave testing methods, and dynamic stiffness via the Humboldt GeoGauge for five representative paving projects covering a range of mixes and traffic loads. The in situ tests were compared against laboratory measurements of core density and dynamic modulus. The in situ PaveTracker density had a low correlation with laboratory density and was not sensitive to variations in temperature or asphalt mix type. The in situ shear-wave velocity measured by surface-wave methods was most sensitive to variations in temperature and asphalt mix type. The in situ density and in situ shear-wave velocity were combined to calculate an in situ dynamic modulus, which is a performance-based quality measurement. The in situ GeoGauge stiffness measured on hot asphalt mixtures several hours after paving had a high correlation with the in situ dynamic modulus and the laboratory density, whereas the stiffness measurement of asphalt mixtures cooled with dry ice or at ambient temperature one or more days after paving had a very low correlation with the other measurements. To transform the in situ moduli from surface-wave testing into quantitative quality measurements, a QC/QA procedure was developed to first correct the in situ moduli measured at different field temperatures to the moduli at a common reference temperature based on master curves from laboratory dynamic modulus tests. The corrected in situ moduli can then be compared against the design moduli for an assessment of the actual pavement performance. A preliminary study of microelectromechanical systems- (MEMS)-based sensors for QC/QA and health monitoring of asphalt pavements was also performed.

Available in PDF, EPUB and Kindle. Book excerpt: The first international symposium on NDT-CE (Non-Destructive Testing in Civil Engineering) was held in Berlin, Germany in 1991. Successive symposia were held throughout Europe until 1997. This, the 5th symposium is organized as SEIKEN SYMPOSIUM No. 26, and is sponsored by the Institute of Industrial Science, at the University of Tokyo, Japan. Original objectives of the NDT-CE symposium have been to provide an opportunity for discussing current issues and future perspectives of NDT and for promoting mutual understanding among engineers and researchers. Asia is one of the key regions for further development in NDT and this symposium in Japan will be a good opportunity not only to exchange technical information on NDT, but to promote worldwide friendship between engineers in Asian countries and other nations of the world. This volume contains 70 papers providing the most recent research results and findings. The papers are grouped under the following areas: (1) keynote papers, (2) magnetic / electric, (3) steel structures, (4) integrated test, (5) moisture, (6) strength, (7) acoustic emission, (8) various tests, (9) ultrasonic, (10) impact echo, (11) radar, (12) quality and (13) corrosion / cover.
