The 2024 MoDOT IC-PMTP Annual Report highlights achievements and challenges in implementing Intelligent Compaction (IC) and Paver-Mounted Thermal Profiling (PMTP) technologies. Key updates included aligning data validation tools with updated PMTP specifications and addressing challenges such as contractor’s paving boundary data manipulation and data loss. Improved PMTP thermal segregation trends were noted, though IC coverage declined due to data loss issues. Feedback meetings emphasized the preconstruction Global Navigation Satellite System (GNSS) and cellular surveys, stricter paving boundary validation, and updated PMTP specifications. Training and support efforts in 2025 will address these challenges and changes, ensuring continued improvement in paving quality and IC/PMTP data reliability.
