• Abstract:
  The final technical report for Phase I of this research project was divided into two parts; R1 and R2. This report
  
  R2 serves as a supplement to Report R1. Report R1 provided a detailed account of research activities conducted
  
  up to the construction of exploratory field test sections in Phase I. This report R2 provides a preliminary analysis
  
  of monitoring data collected from six exploratory field test sections. Based on early data, a seventh test section
  
  was also constructed. However, the data from that section has not been analyzed at the time of writing this
  
  report. The research team will conduct a detailed analysis of data collected from these test sections in
  
  preparation for full-scale test sections to be constructed at the Texas Tech outdoor testing site in the summer of
  
  2017 under Phase II of this project. This research project was designed to be conducted in the following three
  
  Phases, beginning with the development of individual components and ending with the deployment of full-scale
  
  proof of concept highway projects; Phase I: Design and Demonstration (18 months), Phase II: Integration
  
  Component Demonstrations (24 months), Phase III: Final Demonstrations (12 months). Phase I was required to
  
  demonstrate any associated high-risk technologies including the use of material systems to control maximum and
  
  minimum service temperatures in the pavement surface layer, and to improve the quality and performance of
  
  layers supporting it. This is to be followed by Phase II, with integration of technologies determined to be
  
  technically viable in Phase I, while improving constructability and sustainability. Phase I concluded with the
  
  construction of exploratory field testing of novel materials system. Technical work covered in this report were
  
  carried out by seven research groups at Texas Tech University.
