The TSD provides continuous bearing capacity results at both project and network levels while following the flow of traffic. This makes it highly cost-effective. The TSD provides repeatable, detailed and accurate data, from which bearing capacity indices can be derived and pavement fatigue / residual life can be estimated. This information is essential to decide how and where to repair.
TM2
The TM2 is recognized as delivering the definitive macro texture measurement standard. The updated TM2 measures a broad swath of the road profile transversely over a width of 100mm at very frequent intervals to build a detailed record of the surface, with its average texture depth, and delivers repeatable and consistent results. It is widely recognized that pavement texture is an extremely important factor in the control of surface friction and subsequent road safety. It is also an important parameter for the determination of factors such as noise emission from vehicle tyres. The TM2 calculates and stores Root Mean Square Texture Depth (RMSTD) and Mean Profile Depth (MPD) to provide 10 and 50m averages.

Asphalt Pavement Scanner
The Asphalt Pavement Scanner uses radar and infrared sensors to measure compaction, and density without nuclear sources. Produce maps of compaction, density, temperature, and roughness that indicates quality and uniformity. Use for acceptance and risk reduction.
The Asphalt Pavement Scanner measures the pavement’s dielectric constant using advanced radar technology. Compaction and density are calculated from the dielectric constant using a specific calibration for each asphalt mix (similar to a Rice value calibration). The radar sensor and IR temperature sensor continuously scans the surface to produce dielectric, density, compaction, temperature, and roughness maps. Maps of compaction, temperature, and roughness provide a measure of uniformity that cannot be obtained from spot measurements with traditional density gauges. These maps provide better Q/A and Q/C, and ultimately reduced risk and cost.
Non-Nuclear Asphalt Density Gauge
The Non-nuclear asphalt density gauge is a highly advanced dielectric asphalt density gauge specifically designed to increase accuracy and dependability. The NoNuke’s unique algorithm automatically alerts the operator of moisture presence that can negatively affect the accuracy and repeatability of test results.
Strategically placed internal and external temperature sensors measure gauge and pavement temperatures to ensure the gauge is within the operating temperature. Moisture presence warning also will alert the operator of high moisture content in the asphalt pavement. These unique and innovative system checks are built into the NoNuke to continually monitor its environment and produce the best and most accurate test results.
Pavement Instrumentation
The structural responses of a pavement system under actual dynamic loads are of primary concern to design, management, and materials engineers. The planning engineer’s first objective is to style a pavement system that will withstand a specified number of loading cycles. Environmental effects like temperature, which greatly affect the response of flexible pavements, need to be considered also. The pavement management engineer, who is primarily curious about how the performance of the pavement decays with the number of loading cycles, should remember the speed of degradation to implement an efficient maintenance or rehabilitation strategy. The materials engineer, liable for providing a rutting-and-cracking-resistant mix, must evaluate the consequences of heavy loads, high tire pressures, and high and low temperatures on the responses of the asphalt concrete material and supporting layers of soil.
Light Weight Deflectometer
Light Weight Deflectometer (LWD) is designed to measure the in-situ level of compaction of soil materials. The device is intended to be used as a Quality Assurance/Quality Control (QA/QC) device during earthwork construction (e.g. roadway, embankments, trenches, foundations, etc). The device measures the level of compaction by measuring the stiffness and modulus of the soil. Testing is performed directly on the soil layer of interest. However, the device is intended to simulate the loading (loading level and duration) on soil below a pavement from a semi-truck driving at highway speeds. When used for quality control/quality assurance testing, Olson’s LWD-1 system is a powerful, easy to handle and operate tool for verifying compaction level (soil stiffness).

Traffic-Speed 3D Noise Modulated-GPR
The Kerberos is a vehicle-mounted, heavy-duty utility platform engineered to execute high-density 3D NM-GPR surveys at highway traffic speeds without disrupting public road networks. By employing an array-based design, it rapidly gathers overlapping 2D GPR profiles that are cross-correlated to map extensive subsurface volumes covering roads, bridge decks, and airport runways in their entirety. Simultaneously, it leverages integrated auxiliary sensors—including transverse lasers for rutting, inertial measurement units (IMUs), roughness measurement modules (IRI), and photometric stereo vision—to capture synchronized surface defect data. This high-speed capability ensures maximum field crew safety while capturing fine-grained structural data across the sensitive 960–1610 MHz frequency spectrum. The resulting multi-layered datasets allow infrastructure engineers to definitively match underground void developments directly with corresponding surface failures in a holistic model.
