| dc.description.abstract | In recent years, Taoyuan airport runway has been damaged due to the
growth of transportation volume, the trend of aircraft enlargement and high
frequency used airport runway. Taoyuan airport company accomplished the
renovation and expansion of the current southern and northern runway at the end
of 2016; however, the skid resistance of the airport runway is one of the
influences in flight security factor and at the same time, an important indicator
in the pavement maintenance. The proper skid resistance on the pavement
runway could help the aircraft land and stop in the appropriate distance, enable
the aircraft to control its direction when crosswinds or engine failures, and
shorten its′ landing time, etc. Taking off, landing and stop of an aircraft appeared
to result in generating rubber deposits, which accumulate to a certain amount,
will affect the skid resistance of the runway. And the low skid resistance,
however will affect the safety of an aircraft. Therefore, rubber deposits cleaning
on the runway surface and periodically measurement for the anti-slip value has
become one of the most important tasks in flight safety maintenance.
With reference to the relevant literature and related specifications, using the
results of the existing test results, the linear regression equation is used to
predict when the anti-slip values in different seasons are reduced to the threshold
value and the minimum threshold, The anti-slip values in summer are lower than
those in other months, and the anti-sliding values in summer are high. The rate
of decline is 4.8 ‰, which is about 3 times higher than the fall rate of the
anti-slip value at room temperature in the fall. This study explores the
effectiveness of the airport runway rubber deposits cleaning method based on
the test results, whether the threshold value set by anti-slip detection is
reasonable or any inapplicability in current standard operating procedure and
make recommendations for management units to improve the ability of
skid-resistance in domestic airport runway. | en_US |
