APTech's comprehensive 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.

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 roadway and parking lot surveys in accordance with various standards including ASTM D6433-03, Standard Practice for Roads and Parking Lots Pavement Condition Index (PCI) Surveys. APTech has extensive expertise with both portland cement concrete (PCC) and hot-mix asphalt (HMA) pavements and can recommend appropriate treatment options across a wide range of budget scenarios. APTech is experienced in both manual and automated condition assessment. APTech uses vehicles to perform automated data collection. This allows for much faster data collection that can be analyzed from a remote location.  Additionally, because the data can be collected at normal driving speeds, the automated data collection does not impede traffic.

Testing

APTech owns and operates several pieces of equipment that are used as part of its construction inspection and evaluation services, including handheld computers for data collection, GPS cameras, a heavy-weight model falling weight deflectometer (FWD), a coring rig, and a portable seismic pavement analyzer (PSPA).

 

Falling Weight Deflectometer

The FWD is able to simulate loadings ranging from automobile traffic on highways 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.

 

Portable Seismic Pavement Analyzer

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.
