Fifth-Year Monitoring Program of the Prestressed Fibrous Concrete Pavement Constructed at the Greater Rockford Airport.

摘要

This report describes the condition of the prestressed fibrous concrete pavement, fibrous concrete pavement and, conventional Portland cement concrete (PCC) pavement constructed in 1993 at the Greater Rockford Airport, Rockford, Illinois, for the period ending during the summer of 1998. Also included is the data collected quarterly during the quarterly monitoring periods. The collected data includes pavement horizontal movement, daily temperature, stress-stain, crack surveys, pavement condition index (PCI) surveys, nondestructive testing (NDT), and other information. The gauges were placed in the prestressed pavement during construction. The data collected was analyzed to report interested trends in pavement performance and validate design assumptions. The quarterly monitoring were conducted during November 1997, February 1998, April 1998, and August 1998. The three pavements were constructed along Taxiway F in 1993 to demonstrate methods to minimize longitudinal and transverse joints in PCC pavements. The innovative paving techniques used to minimize joints, while standard construction techniques for bridges and buildings, had never before been tried in an airfield pavement. The techniques resulted in a 1,200-foot-long prestressed fibrous PCC pavement, a 900-foot-long fibrous PCC pavement with transverse joint spacing varying from 85 to 200 feet, and a 561-foot-long conventional PCC pavement with 12.5- by 15-foot joint spacing.
