SURFACE INTEGRITY - AIRFIELD PAVEMENT CONDITION ASSESSMENT

This paper presents current airfield pavement condition assessment and rating methodologies used by the US Air Force and the Avinor (Norway). Factors included in the ratings include the Pavement Condition Index (PCI), Structural Index (ACN/ PCN), Friction Characteristics, Surface Texture, Foreign Object Damage (FOD) potential and evenness The PCI is a score from 0 to 100 that is determined by a visual survey of pavement distress based on procedures in ASTM D 5340. The Structural Index is a ratio of the Aircraft Classification Number (ACN) to Pavement Classification Number (PCN). ACN represents the structural impact an aircraft will have on a pavement. PCN represents the structural capability of the pavement to support aircraft. Friction Characteristics are primarily determined for runways using a variety of measuring equipment. Surface texture is a parameter that can be used by pilots on civil aircraft to predicting the maximum tire-to-ground wet runway breaking coefficient. The FOD Index is used to indicate the potential for FOD problems generated by the pavement. It is determined based on pavement distresses collected during the PCI survey. Evenness is essential for the ride quality of a pavement. On Airfields, there are requirements both to short- (3m) and long wave (45m) unevenness. The paper presents procedures used in determining each of the above factors and also how these factors can be used collectively to determine the overall rating of airfield pavements.
