Abstract:

Runway pavement grooving has been commonly constructed to reduce aircraft hydroplaning risk and the loss of pavement skid resistance during wet weather. In a recent Federal Aviation Administration (FAA) experimental study, a new trapezoidal grooving design for runways was found to offer several benefits over the current FAA standard square grooving design, including improved water evacuation capability, greater resistance to rubber contamination, better integrity, and improved longevity. However, the experimental study did not produce conclusive findings on the relative skid resistance and hydroplaning performance of the two grooving designs. This is a critical issue of concern as one must ensure that in the process of improving the durability, integrity and longevity of the grooves, the safety performance (skid resistance and hydroplaning risk in particular) of the grooved pavement is not compromised. To address this issue, this paper presents a finite element simulation model to evaluate analytically the relative skid resistance and hydroplaning performance of the two grooving designs. Also presented is another finite element model to evaluate their drainage capacities to explain their different hydroplaning and skid resistance performance. The results show that the trapezoidal grooving design gives marginally lower skid resistance at low aircraft sliding speeds, but its better drainage capacity allows it to maintain slightly higher skid resistance than the square grooving design at high sliding speeds. On hydroplaning, the trapezoidal grooving design offers slightly lower hydroplaning risk due to its better drainage capability.
