I-55 OGFC Field Permeability Testing

An OGFC test section was constructed on I-55 in Copiah County, MS during the spring/summer of 2007. As part of the study, literature was reviewed and a falling head permeability device was identified that has been used in laboratory and field studies of OGFC/PFC permeability. The falling head device was fabricated along with a vehicle mounted reaction frame. Drawings for the apparatus are included in the report. In situ permeability tests were conducted in wheel paths and between the wheel paths of the driving and passing lanes of the highway in one tenth mile increments. The measurements were initiated approximately six months after construction and then every six months for two and one-half years. A goal of the research was met in that it has been shown OGFC can be successfully designed using local Mississippi aggregates and polymer modified asphalt. In service, the resulting OGFC can carry significant traffic while maintaining an adequate level of in situ permeability. The OGFC did not exhibit loss of aggregate through surface raveling or significant spalling along cracks generated at the juncture of the laydown machine screed and screed extensions during construction.
