23 Data Interpretation and Application The research team submitted the following chapters as Part III--Data Interpretation and Application. This part is published herein as Chapters 1, 2, and 3 of NCHRP Report 626. The chapters describe the physical characteristics and process for using each NDT technology and devices on construction projects to define construction quality. Each system was evaluated in two parts: (1) the system's potential to be integrated into the flexible pavement construction process (level of process impact) and (2) the reliability and accuracy of the system (system accu- racy and reliability). Chapter 1 focuses on the level of process impact on construction. In other words, what impact will the device have on the contractor's progress, and will agencies need sub- stantially more staff to use the technology? Chapters 2 and 3 focus on the system accuracy and reliability of the different technologies and devices included in the field evaluation study.
