Precast Concrete Pavements for Slab Replacement extends from years 3 to 7; Problem Statement RC 2.3. Lightweight Precast Concrete Pavements extends from years 7 to 10; Problem Statement RC 2.4. Precast Joints for Joint Replacement extends from years 5 to 9; and Problem Statement RC 2.5. Precast Quiet Pavement Surfaces extends from years 5 to 10.

In subtrack 3 the problem statements are arranged as follows: Problem Statement RC 3.0. Framework for Fast-Track Concrete Pavements extends from years 1 to 3; Problem Statement RC 3.1. Synthesis of Practice for Accelerated (Fast-Track) Paving extends from years 2 to 4; Problem Statement RC 3.2. Accelerated Paving Techniques extends from years 3 to 7; Problem Statement RC 3.3. Accelerated Hydration Methods extends from years 4 to 8; and Problem Statement RC 3.4. Accelerated Concrete Pavement Restoration Techniques extends from years 4 to 9.

In subtrack 4 the problem statements are arranged as follows: Problem Statement RC 4.0. Framework for Rehabilitation and Construction Evaluation and Implementation extends from years 1 to 3; Problem Statement RC 4.1. Workshops on Fast-Track Concrete Paving extends from years 2 to 10; Problem Statement RC 4.2.
