落锤式弯沉仪
A falling weight deflectometer reproduces the load pulse of a moving wheel and records the full deflection bowl, which is what backcalculation of layer moduli needs. We build trailer-mounted and vehicle-integrated FWDs for highways, a heavy weight unit for airfields, a compact trailer for low-volume roads, and a reference calibration system. Peak load, number of geophones and survey speed decide the right model. Testing follows ASTM D4694, with AASHTO R 32 covering calibration.
Single instruments, complete laboratories or government tenders — our export engineers prepare the configuration, proforma invoice and shipping documents.
