Rut depth measurement method and analysis at the FAA's National Airport Pavem…

The FAA developed and modified a truss profiler, which is independent of pavement profiles, that is used to monitor rutting of flexible pavements at the National Airport PavementTest Facility (NAPTF). The truss profilerwas developed to replace the more labor-intensive and time-consuming straightedge measurements. Transverse profiles corresponding to the cumulative number of load repetitions app…

Study of Failure Mechanisms in Rubblized Concrete Pavements with Hot Mix Asph…

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 …
