• 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.
