DG Track 2:

Performance-Based Design Guide for New and Rehabilitated Concrete Pavements

Goals

The goal of this track is to continue enhancing the next generation of mechanistic approaches to pavement design and improving their integration with materials, construction, and environmental inputs. A major element of the track is helping agencies and contractors successfully make the change from strictly empirical design approaches to mechanistic approaches.

Activities to Date

  • Work is underway to develop a guide that outlines the existing concrete overlay design process, defines the key inputs, and provides numerous design examples and typical cross-sections.
  • Industry and State DOTs are investigating the size and spacing of concrete tie bars to make their use more efficient and economical.
  • The team is planning to evaluate the effect of construction practices on concrete materials properties and develop new tests for characterizing concrete strength and modulus that better reflect field behavior.
  • A future project will look at ways to improve distress and smoothness prediction models for jointed plain concrete pavement (JPCP). This project will result in more cost-effective and reliable designs for JPCP.
