• Resumen

  • This paper describes in detail the laboratory and field evaluation of runways at two airports: Double Eagle II at Albuquerque and Sierra Blanca at Ruidoso, New Mexico.

    Field skid resistance test, Falling Weight Deflectometer (FWD) test, and coring are carried out. Cores and soil samples are collected and tested in the laboratory. The CBR values and the skid numbers were compared to the tables in Advisory Circulars 150/5320-6D and 150/5320-12C to make an assessment. The modulus values from FWD data are presented in a 2D contour plot to determine the distress area of each runway. The structural health of the pavement of runway 17-35 at Double Eagle II airport is in a good condition while runway 4-22 of the same airport is not in good condition based on the resilient modulus and CBR values. As for Sierra Blanca airport, runway 6-24 is in a good condition while the surface of the runway 12-30 needs attention.
