Book Description
The focus of the study has been to evaluate the utility of seismic methods in the quality management of the hot mix asphalt layers. Procedures are presented to measure the target field moduli of hot mix asphalt (HMA) with laboratory seismic methods, conduct field tests with the Portable Seismic Pavement Analyzer (PSPA) in the field, validate the results in the laboratory with seismic tests on extracted cores and determine the design modulus from measured values. This report contains the results of an effort to address the issues related to the implementation of the recommended methods and devices in the day-to-day operation of the pavement community (in general) and pavements managed by the Arizona Department of Transportation (ADOT). Ten sites throughout Arizona with different pavement conditions and structures were tested between August and December 2005. The results are summarized in this report. Based on the results presented, the combination of the lab and field seismic methods is a viable tool for the quality management of HMA layers and can be easily implemented by ADOT. In addition, performing the simplified seismic laboratory and field tests along with more traditional tests may result in a database that can be used to smoothly unify the design procedures with pavement evaluation.

Book Description
Non-destructive testing (NDT) devices, such as the light weight deflectometer (LWD) and the portable seismic pavement analyzer (PSPA), provide a non-destructive and portable means of quick in-place determination of pavement properties, resulting in an increase in sampling frequency to supplement coring. A preliminary sampling procedure was developed for the PSPA as a quality control tool in Louisiana.

Book Description
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.

Book Description
"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
