Figure 3. Bar Chart. Track 3 (ND) subtrack and problem statement phasing chart.

Track 3 (ND) subtrack and problem statement phasing chart.The horizontal bar chart in this figure shows the approximate time phasing of the problem statements in track 3, High-Speed Nondestructive Testing and Intelligent Construction Systems (ND), grouped by subtrack across 10 years. There are three subtracks in track 3: (1) Field Control; (2) Nondestructive Testing Methods; and (3) Nondestructive Testing and Intelligent Control System Evaluation and Implementation.

In subtrack 1 the problem statements are arranged as follows: Problem Statement ND 1.0. Framework for Field Control extends from years 1 to 3; Problem Statement ND 1.1.

Field Validation of Field Quality Control/ Quality Assurance Tests extends from years 4 to 10; and Problem Statement ND 1.3. Revise Performance-Related Specifications to Include Concrete Mix Properties extends from years 5 to 10.

In subtrack 2 the problem statements are arranged as follows: Problem Statement ND 2.0. Framework for Nondestructive Methods extends from years 1 to 3; Problem Statement ND 2.1. Concrete Temperature and Moisture Sensing extends from years 2 to 6; Problem Statement ND 2.2. Concrete Pavement Thickness Sensing extends from years 3 to 7; Problem Statement ND 2.3. Dowel/Tie Bar Alignment Sensing extends from years 4 to 8; Problem Statement ND 2.4. Concrete Curing Effectiveness Sensing extends from years 4 to 8; Problem Statement ND 2.5. Concrete Pavement Support Sensing extends from years 5 to 9; Problem Statement ND 2.6. Workability Sensing extends from years 5 to 9; Problem Statement ND 2.7.

Concrete Pavement Smoothness Sensing extends from years 3 to 6; Problem Statement ND 2.10. Concrete Pavement Texture (Skid Resistance, Splash/Spray) Sensing extends from years 5 to 10; Problem Statement ND 2.11. Tire-Pavement Noise Sensing extends from years 8 to 10; and Problem Statement ND 2.12. Integrated Intelligent Concrete Paving System extends from years 7 to 10.

In subtrack 3 the problem statements are arranged as follows: Problem Statement ND 3.0. Framework for Nondestructive Testing and Intelligent Control System Evaluation and Implementation extends from years 1 to 3; Problem Statement ND 3.1. Workshops on Field Quality Control Testing of Concrete Pavement extends from years 4 to 10; Problem Statement ND 3.2. Workshops on Nondestructive Testing and Evaluation of Concrete Pavements extends from years 2 to 10; Problem Statement ND 3.3.
