Airport Master Plan 2012 - City of Waterville

Currently, the Airport pavement conditions can be summarized as follows:
Table 1.5
Airport Pavement Conditions
Designation Condition Comment
Runway 5-23
Fair to Good
Moderate longitudinal cracking, some transverse and
randomly oriented shrinkage cracking
Runway 14-32 Very Poor Extensive shrinkage cracking
Taxiway “A” Fair to Good Longitudinal paving lane joint cracking
Taxiway “B” Fair Numerous cracks with vegetation growth
Taxiway “C” Fair Shrinkage cracking
Taxiway “D” Excellent Reconstructed in 2007
Taxiway “G” Fair Moderate lane joint and shrinkage cracking
Taxiway “H” Fair Moderate lane joint and shrinkage cracking
The condition of the bituminous pavement is generally fair to good over the entire length of Taxiway “A”
which runs parallel to RW 5-23. The most prevalent distress is in the form of moderate severity,
longitudinal paving lane joint cracking. Transverse shrinkage cracking also exists, along with some
localized patch repairs that have been made over time.
There is very little spalling, aggregate raveling, rutting, alligator cracking, or settlements that were
evident due to heavy loading, unsuitable or variable subgrade materials, or frost conditions. No
settlements resulting from drainage or utility trench crossings were observed. There does not appear to be
significant rutting or settlements in the surface that would indicate severe structural deficiencies within
the pavement section. Taxiway shoulders and safety areas appeared to be properly graded, structurally
adequate, and well maintained.
The most recent improvements to Taxiway “A” included an extension to the Runway 5 end, which was
completed in 1987.
Runway Safety Areas
FAA runway safety standards require a 500-foot wide safety area that extends 1,000 feet beyond both
ends of Runway 5-23. Initial inspection suggests the potential to meet this standard, however a full
topographic survey is required to confirm actual grading conditions; this extensive survey effort was not
included in the project scope of work. RSAs beyond runway ends consist of turf (Runway 5 end) or old
bituminous pavement (Runway 23 end), are generally well graded, structurally stable, free of
obstructions, and have been maintained. Runway shoulders and lateral safety areas were properly graded,
firm and well maintained, with no obstructions visible at the time of the inventory.
Runway 14-32 has a 120-foot wide safety area along the entire runway length that also extends 240 feet
beyond each end of the runway. Runway 14-32 safety areas beyond runway ends consist of turf and are
generally well graded, structurally stable, free of obstructions, and have been well maintained.
Runway shoulders and lateral safety areas were properly graded, firm and well maintained, with no
obstructions visible at the time of the inventory.
