Consultant Support for Intelligent Compaction and Paver-Mounted Thermal Profiling Projects in 2022-2023

MoDOT's Intelligent Compaction (IC) and Paver-Mounted Thermal Profiling (PMTP) projects from 2017 to 2021 showed improvements in paving quality, leading to an extension of these projects into 2022 and 2023. The aim was to procure consulting services to maintain the success of IC-PMTP projects. The project spanned 26 months, from March 2022 to April 2024, with this report summarizing the progress in 2023. Key trends since 2017 include increased IC pass count coverage, reduced temperature segregation, and consistent compaction temperatures, indicating enhanced construction practices and pavement quality. MoDOT is dedicated to further developing the IC-PMTP program, focusing on statewide implementation, evolving specifications, comprehensive training, and employing innovative technologies. The 2023 highlights include the adoption of automated boundary collection methods, evolving IC and PMTP specifications with new classifications and price adjustments, a detailed training program, and plans to address cellular or GPS coverage issues in future projects.
