APTech's comprehensive airport pavement evaluations provide insight into how the pavement is performing, what is causing it to deteriorate, and what additional information is needed to determine the most appropriate repair or rehabilitation option.

 APTech is experienced in all methods of pavement condition assessment, including visual inspections and pavement testing for clients ranging from small general aviation airports to large-hub airports and Air Force Bases. APTech regularly accommodates the busy schedules of airports by performing night work and remaining responsive to the scheduling needs of the client.

Condition Assessment

APTech conducts pavement condition surveys as part of its core services and has performed surveys on thousands of pavement facilities. APTech has extensive experience conducting airfield surveys in accordance with various standards including ASTM D-5340-11, Standard Test Method for Airport Pavement Condition Index Surveys. APTech not only uses this specification but was instrumental in the 2010 and 2011 updates to it. The 2010 update incorporated a new distress type for alkali-silica reactivity (ASR) for portland cement concrete (PCC) pavements and split weathering and raveling into two distresses for hot-mix asphalt (HMA) pavements, while the 2011 update corrected a calculation when combining multiple distresses of varying severity levels. APTech has a representative on that ASTM committee and provided valuable insight into these changes from a user’s standpoint.

Testing

APTech owns and operates several pieces of equipment that are used as part of its construction inspection and evaluation services.

 

FWD

The FWD is able to simulate loadings ranging from light, single-engine aircraft to the heaviest aircraft on large commercial airport runways.  It is able to apply loads up to 55,000 pounds.  FWD testing allows for the evaluation of multiple locations in a short period of time without disturbing the pavement structure.

 

Coring

APTech also owns and operates a trailer-mounted material sampling device that can be used to obtain core and auger samples of the pavement and subsurface layers.  Samples obtained by the device can be tested in a number of ways to determine layer thickness, unit weight, strength, stiffness, and other intrinsic material properties.  APTech has used this sampling technique to diagnose subsurface causes of deterioration for airport pavements when surface observation could not.

 

PSPA

APTech most recently added to its equipment the PSPA.  The PSPA is a nondestructive testing device that measures the seismic modulus of concrete pavements.  It also identifies transitions between asphalt lifts and changes in modulus depth.  Using the PSPA, APTech is able to estimate thickness via the impact echo method.
