Abstract:
The friction of runway pavement is critical for the safety of aircraft landing
and movement on the runway. Tire hydroplaning may lead the aircraft to move off
the runway and hinder the safe landing during wet weather conditions. Grooving
on the runway is one way to develop frictional braking resistance and diminish
hydroplaning’s potential risk by improving runway surface drainage capacity during
damp weather. According to the Federal Aviation Administration (FAA), groove
construction must follow specific dimensions to maintain skid-resistant airport pavement
surfaces. However, the groove area can be reduced for several reasons, and
regrooving is essential if 40% of the runway groove of a substantial length decreased
to 50% of its original dimension. Grooves initiate different potential distress mechanisms
that are not found in an ungrooved pavement surface. Groove closure in
different airports with hot weather is a frequent and prominent form of distress that
substantially declines the grooves’ effectiveness. Moreover, the degree of the declination
of groove dimensions has not been quantified in a theoretical method. This paper
discussed the current technique and importance of runway grooving. In addition to
this, this paper reviews different potential distress mechanisms and issues related to
groove deterioration. Finally, a brief of a predictive modeling requirement is illustrated,
which is significant for the authority concern for maintenance and reinstate
the grooving in the runway for friction development.
