Portable Light Weight Deflectometer for Pavement Testing

Product Description

Product Description
Applicationevd dynamic deformation modulus testerUSAGE OVERVIEWThe GTJ-EVD type Light weight deflectometer is used to determine the deflection capacity of the subgrade under the dynamic load, thereby evaluating the bearing capacity and deformation of the subgrade. It is suitable for monitoring and testing the construction quality of railway, highway, airport, urban traffic, port, wharf and industrial and civil buildings under dynamic loads, especially in narrow areas, such as bridge transition section and shoulder detection, existing line subgrade, etc. Compared with the static load test, the instrument can simulate the impact effect of high-speed train on subgrade, which can better reflect the actual stress of subgrade soil. It can quickly measure the dynamic deformation modulus Evd value.Main Features1.Pioneer Phone APP for wireless transmission and voice prompt function.2.Imported sensors are used, which has high test accuracy and more reliable test data.3.Easy to operate and fast to test. It takes only 35 seconds to detect a point.4.The Evd value is calculated automatically and the curve is displayed accurately and intuitively.5.Non-nuclear radiation and exhaust gas pollution, safe to operation and environment.Technical ParametersTest CoverageApplication Soil TypesSoil-rock mixed fillers with particle size less than 1/4of the diameter of loading plateTest scope10Mpa≤Evd≤225MpaTest impact depth0~500mmWork environmentTemperature: -10~40℃ Humidity: ＜90%HRDate-collecting deviceLoading deviceWeight15KGsDrop weight10KGsDropping height of drop hammer 700±20mmMaximum impact force7.07kNShock duration 18±1msLoading plateWeight15KGsDiameter300mmThickness20mmPacking specificationHost boxMaterialengineering plasticsVolume420×140x335mmWeight4.5GKsOuter packing boxMaterialAluminum alloyVolume1220x395x380mmWeight56KGsIf you have any questions or need more detailed information please just contact us!
