Full-scale traffic tests were completed on three rubblized rigid airport pavements overlaid with 5 in. (130 mm) of hot-mix asphalt at the FAA's National Airport Pavement Test Facility. Initially, the overlaid pavements were trafficked with a four-wheel landing gear (with wander) and 55,000-lbs (25-tonne) wheel load. No significant distresses were observed during the 5,000 passes, after which the wheel load was increased to 65,000 lbs (29.5 tonnes) and a six-wheel landing gear was used for testing. The rubblized concrete pavement on conventional base section (MRC) exhibited complete structural failure. The rubblized concrete on subgrade (MRG) section exhibited severe structural deterioration at the end of trafficking, but retained sufficient structural capacity to support the applied load. The rubblized concrete over econocrete base section (MRS) did not exhibit severe structural deterioration at the end of trafficking. Four trencheswere opened perpendicular to the centerline of the test sections to conduct post-traffic investigation into the failure mechanism of the pavement structure. The trenching included testing for layer characterization (plate load tests, California Bearing Ratio tests, in situ densities, moisture contents, layer profile measurements, and visual evaluations) and removal of each pavement layer to reveal the subgrade interface and subsequent subgrade layers below. This paper summarizes the results from the post-traffic tests. The performance of the MRS test section suggests that rubblized concrete pavements with HMA overlay are a viable option on commercial airports. The results from post-traffic tests were useful in providing insight into the failure mechanism of rubblized concrete pavements. © 2012 Taylor & Francis Group.
