Implementation of Data Quality Assurance (QA) for Innovative Technologies at MoDOT

Intelligent construction technologies (ICTs) combine modern science and innovative construction technologies. The goal of ICT is to improve the quality of construction, save costs, and improve safety. The ICTs described in this report include intelligent compaction (IC), paver-mounted thermal profiler (PMTP) equipment, and dielectric profiling systems (DPS). IC and PMTP systems are mounted on contractor paving equipment. Therefore, the data generated by these systems is collected by the contractor. DPS systems can be owned and operated by the agency or contractor.

Meeting the Code of Federal Regulations (CFRs) for construction acceptance using ICT is a national issue but a worthwhile endeavor to ensure the ICT produces quality data for construction acceptance decisions. MoDOT is among the leading DOTs working towards satisfying the requirements to implement ICT. This project's main objective is to advance MoDOT's efforts to obtain data QA solutions for ICT.
