Four test sections of the jointed reinforced concrete pavement (JRCP) on Interstate 86 in Olean, NY will be rehabilitated using various methods. To compare the results of these techniques with the pavement’s initial condition a detailed forensic investigation was performed. Non-destructive tests were conducted with distress surveys, the Falling Weight Deflectometer, and Georgia faultmeter, along with destructive testing by using the dynamic cone penetrometer and removing concrete cores. Data gathered were used to inspect the quality of the base materials and the concrete slabs and joints.
Opened in 1972, I-86 has had no rehabilitation outside of minor asphalt patching and crack sealing. Because of this the JRCP exhibits an array of distresses, of which faulted transverse cracks and corner breaks were the most prominent. The pavement condition index (PCI) was determined for each test section using ASTM D 6433-03, while the functionality of the pavement was modeled using ACPA Pavement Analysis Software and the FHWA Rigid Pavement Design Program. The results of these analyses verified the need for rehabilitation of this pavement and allowed for predictions to be made for the next phase of testing.
