FRT 221, I-265 Pavement Forensics in Jefferson County I-64/I-265 Ramps

The intent of collecting pavement forensic data will allow design engineers to better understand the existing pavement structure quality and characteristics that can be utilized in this specific pavement design and in future pavement designs. KTC will coordinate with KYTC maintenance staff to secure the necessary in-house traffic control to perform the following work items as noted previously in table one and described below: Ground Penetrating Radar (GPR), and limited coring as necessary to calibrate GPR data. - Perform GPR testing in the left lanes only, to determine pavement and sub-base thickness variation along the I265 corridor. Collect and analysis GPR data on the four non-cloverleaf sections of the I64/I265 ramps. - Core pavement structure and hand-dig through sub-base material to sub-grade for verification thicknesses, as necessary to calibrate GPR data. Testing frequency will be performed in both directions in the left lane only and all four non-cloverleaf sections of the I64/I265 ramp area. Reduced forensic data will be conveyed back to KYTC using an ArcGIS mapping platform.
