"FWD" is a diagnostic technology that applies an impact load (standard 49 kN) to a paved surface and measures the deflection occurring in the surface using multiple displacement sensors at varying distances from the loading point. This allows for a non-destructive evaluation of the pavement structure from the obtained deflection curve. It enables the assessment of the pavement's integrity and the CBR of the subgrade without damaging the pavement. By performing inverse analysis of the deflection, it is possible to determine the remaining thickness of the pavement layers and their elastic coefficients. 【Features】 ■ Allows for the evaluation of the pavement's integrity and the CBR of the subgrade without damaging the pavement ■ By measuring at many points, it is possible to identify sections or layers that require repair ■ Can determine the remaining thickness and elastic coefficients of the pavement layers ■ Manufactured by Grontmij in the Netherlands, equipped with a loading plate, heavy weights, load measurement devices, and deflection measurement sensors in a one-box vehicle *For more details, please refer to the PDF materials or feel free to contact us.

The "Field Density Test" is a test conducted to determine the density of materials such as fill in their natural state, and it is widely performed, particularly for construction types that require compaction management. As information-based construction using TS and GNSS is implemented, there is an increasing number of tests conducted on test fills aimed at determining factors such as the number of compactions, further expanding the scope of its application. Please feel free to consult us when needed. 【Overview】 ■Field: Excavation of test holes, sand injection for testing ■Laboratory: Weighing of residual sand, weighing of excavated soil (moist), weighing of excavated soil (dry) ■Calibration: Measuring the mass of the measuring device, measuring the mass of the measuring device and sand, measuring the mass of the measuring device and water *For more details, please refer to the PDF document or feel free to contact us.

Our company offers "Plate Load Testing Services for Ground". In this service, we determine the characteristics of ground deformation and bearing capacity based on the magnitude of the load applied to the ground and the amount of settlement of the loading plate. It is suitable for confirming the bearing capacity of building foundations, the bearing capacity of ground for retaining walls, and the bearing capacity of ground for culverts. 【Features】 ■ Determine the characteristics of ground deformation and bearing capacity based on the magnitude of the load applied to the ground and the amount of settlement of the loading plate. ■ Conduct plate load tests on roads as well. *For more details, please refer to the PDF document or feel free to contact us.
