• Abstract:
  Due to the success of the Missouri Department ot Transportation (MoDOT) 2017 Intelligent Compaction (IC) and Infrared Scanning (IR) projects that demonstrated quality control improvements on 13 field projects, MoDOT established a plan that included further IC and Paver-mounted Thermal Profile Systems (PMTPS) projects in 2018-2019 with a goal of full implementation in 2021. To ensure the continued success of the MoDOT IC-PMTPS projects in 2018 and beyond, MoDOT procured Consulting Support for the selected IC-PMTPS projects in 2018-2019 (i.e., Phase II). This document details the results from the 2019 IC-PMTPS Projects and an average of overall results from 2017 to 2019. There was a significant improvement in IC and PMTPS data management and analysis efforts by contractors from 2017 to 2019. The thermal segregation continually improved from 2017 to 2019 according to AASHTO PP80 definitions of thermal segregation. There was a significant improvement in IC coverage from 2018 to 2019. Based on the 2017-2019 projects and lessons learned, recommendations for future implementation are included in the study.
