Model: FWD-L100
Standard: ASTM E2835-11, ASTM D4695, TB10414-2003 / TB10102-2004(China), TP BF-StB (Germany)
The falling weight deflectometer is used to measure the vertical deflection of the load plate response of a surface to an impulse load. the deflections is either correlated to pavement surface or used to determine characteristics of the materials used for the pavement foundation. It can quickly & precisely obtain the dynamic deformation modulus (Evd value) of soil and other construction materials.
The deflectometer is comprised of a loading mechanism, a loading plate, a electronic settlement measuring device.
Features
a. Faster & lower cost
Within 3mins for each test point, rapid results obtained;
No external loading device needed, no pollution, no nuclear
b. Easy operation, human-friendly
Light in weight, compact size, human-friend design
Easy access to even narrow test place.
c. Reliable, higher accuracy
Key parts such as Sensor, data logger, loading damper are original imported types from Germany, guarantee high reliability and accuracy.
