Home About Us Practice Areas Technologies Careers News Contact Us GPR Ground Penetrating Radar (GPR) GPR is a state-of-the-art testing methodology that uses the principle of propagation of electromagnetic waves. It can be used to locate buried objects or obtain various subsurface attributes. Depending on the type of application, air-launched or ground coupled antenna configurations of different frequencies can be used. For concrete applications, GPR can determine the location and depth of rebar (mapping), wire-mesh, steel beams, post tension cables, pipes or conduits. For bridge deck inspection, GPR can be used to evaluate the rebar deterioration at or above the level of the top layer of reinforcing bar on either concrete or asphalt overlaid decks. It can also be used to accurately determine thickness of bound pavement layers such as bituminous, concrete, and stabilized bases. For utility location, GPR is an excellent tool for locating and mapping metallic and non-metallic utilities or underground tanks. On geophysical applications, GPR can be used to detect underground voids and sinkholes or identify the depth to bedrock.

Home About Us Practice Areas Technologies Careers News Contact Us Pavement Management Utilizing a testing van outfitted with a full array of testing capabilities, AID collects pavement and other asset data at posted speeds without interruption to traffic. Integrating 3D-laser imaging, video, Ground Penetrating Radar (GPR), Inertial Profiler, and GPS technologies, a wide range of pavement performance and asset condition data is collected on the fast track. AID routinely utilizes this system to collect FHWA Highway Performance Monitoring System (HPMS) data and other performance data customized for its clients, such as the NJ Turnpike Authority and various counties and MPO’s. In addition to roadways, AID collects both airside and landside pavement condition data for airports, making use of its high-speed testing vehicle to minimize interruptions under tight testing windows. Data collection is just the beginning for AID’s Pavement Management System services. Once collected, processed, and quality checked, the data is put to work to report pavement condition, identify cost-effective pavement solutions, prioritize sections within the network, and deliver an optimized treatment plan.
