GPR Analysis of I-70

As part of Pooled Fund TPF-5(385) Infrasense collected ground penetrating radar (GPR) on I-44 from mile marker 113 to 129 in both the eastbound and westbound directions. This data was collected to supplement continuous deflection testing performed along the I-44 corridor and the data was analyzed by Infrasense in project TR202301. MoDOT wishes to do further testing on the I-70 corridor that will be collected as part of the pooled fund project in the spring of 2023. Since the GPR data analysis was not part of the pooled fund study this project would provide the funding to analyze the data and compare it to the continuous deflection data. Having baseline data for the I-70 corridor is important for understanding the condition of the pavement and could be beneficial for any reconstruction activities in the future. The deliverables from the analysis will include pavement layer thickness, layer elastic moduli, required overlay thickness estimate, and remaining service life estimate.
