We are offering locally manufactured KUAB 70-150 SPGE Falling Weight Deflectometer, (FWD), a mobile system performing non-destructive dynamic plate loading tests with a falling weight as force generator. The peak load, the rise time and the shape of the impact load simulate traffic load. A flexible load distributing loading plate gives a uniform and reproducible stress distribution. Seismic deflection transducers accurately measure the shape of the deflection basin. In addition to the basic measurement of load and deflections, KUAB 70-150 SPGE measures the test point position, the air temperature and the pavement surface temperature. This model is designed to meet and slightly exceed the requirements laid down in IRC 115-2014 & 117-2015 Guidelines for Structural Evaluation and Strengthening of Flexible Road Pavements using Falling Weight Deflectometer (FWD) technique. This system is available in 70 kN to 150 kN versions with 7 or 9 sensors, both in Trailer Mounted and Vehicle Mounted versions.
