The pavement response is analyzed with Dynatest's ELMOD (Evaluation of Layer Moduli and Overlay Design) software to determine the elastic moduli, stresses and strains of each modeled layer. ELMOD reports the weakest layer of failure, residual life and determines the optimum rehabilitation alternatives.
The Fast FWD (Fast Falling Weight Deflectometer) is 5 times faster per drop than the original FWD and as with the FWD (Falling Weight Deflectometer) is designed to impart a load pulse to the pavement surface simulating the load produced by a moving vehicle.
The HWD is highly versatile and can be used to test on both rigid, paver block and flexible pavements on roads and airports. The HWD can apply a loading in the range of 30-320kN, enabling it to simulate vehicle loading from to the most extreme aircraft wheel load such as the Boeing 777, the Airbus 340 or 380.
The Light Weight Deflectometer uses a load cell and geophones with the same accuracy as the Falling Weight Deflectometer. The LWD can be used to test thin asphaltic pavements, recycled materials bound with foamed bitumen and directly test the unbound subbase and subgrade. The output from the LWD can be used to calculate the strength of multiple pavement layers.
The MFV measures the IRI/RN, longitudinal and transverse profile, macrotexture, raveling and geometrics (crossfall, gradient, and radius of curvature). 2D or 3D pavement imagery from the LCMS across a 4m width enables rapid and objective crack detection and crack classification, and up to 8 Right of Way cameras, providing a complete view of the road and assets.
The Troxler nuclear moisture density gauges are used by many contractors, engineers, and highway departments for compaction control of soil aggregate, concrete, and full depth asphalt. The operator selects the density measurement mode, backscatter, or direct transmission based on the material type and the thickness of the layer being measured.
The PaveTracker Model 2701-B Plus is an electromagnetic density indication device for asphalt quality control measurements. This gauge contains no radioactive material, so no licensing or special training is required to own or operate this equipment. Your entire asphalt paving team could be ready to perform asphalt quality control measurements at a moment’s notice.
The Dynatest 5051 Mk-III Road Surface Profilometer measures a number of indices and characteristics including the longitudinal profile, International Roughness Index (IRI), Ride Number (RN), transverse profile, rutting, macrotexture, and geometrics (crossfall, gradient and radius of curvature).
The RSP-IV is the portable version easily attached to any vehicle with the capability to attach 1 or 2 lasers. Options include texture capable lasers, DGPS, and ROW cameras.
