Novel Material Systems for the Next Generation of Flexible Pavement Structures – Phase 1 Preliminary Analysis of Field Test Data

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.
