Figure 9. Bar Chart. Track 9 (DC) subtrack and problem statement phasing chart.

Track 9 (DC) subtrack and problem statement phasing chart.The horizontal bar chart in this figure shows the approximate time phasing of the problem statements in track 9, Concrete Pavement Accelerated and Long-Term Data Collection (DC), grouped by subtrack across 10 years. There are three subtracks in track 9: (1) Planning and Design of Accelerated Loading and Long-Term Data Collection; (2) Preparation of Data Collection/Testing Procedures and Construction of Test Road; and (3) Accelerated Loading and Long-Term Data Collection Implementation.

In subtrack 1 the problem statements are arranged as follows: Problem Statement DC 1.0. Framework for Planning and Design of Accelerated Loading and Long-Term Data Collection extends from years 1 to 3; Problem Statement DC 1.1. Identification of Accelerated and Long-Term Data Needs extends from years 2 to 5; Problem Statement DC 1.2. Concrete Pavement Data Management and Distribution extends from years 2 to 4; Problem Statement DC 1.3. Master Plan for Conducting Accelerated Testing of Products and Full-Scale Road Experiments extends from years 3 to 7; and Problem Statement DC 1.4. Develop Experimental Designs and a Data Collection and Performance Monitoring Plan for Accelerated Loading Facilities and Full-Scale Products Testing extends from years 3 to 7.

In subtrack 2 the problem statements are arranged as follows: Problem Statement DC 2.0. Framework for Preparation of Data Collection/Testing Procedures and Construction of Test Road extends from years 1 to 3; Problem Statement DC 2.1. Preparation of Concrete Pavement Data Collection and Testing Procedures extends from years 2 to 7; and Problem Statement DC 2.2. Construction of Accelerated Loading Sections and Test Road Sections extends from years 2 to 10.

Subtrack 3 contains only one problem statement: Problem Statement DC 3.1. Implementation of Accelerated Loading and Long-Term Data Collection extends from years 1 to 10.
