The HMP LFG 4 light drop weight tester also referred to as Light weight deflectometer or LWD  is a portable  dynamic impulse plate load tester based on accelerometer sensor used  for determining the soil bearing capacity and compaction quality of soils and non-cohesive sub-bases.

Conforming to the latest ASTM E2835 standards and the  German Technical Test Standard For  Soil and Rock In Road & Railway Construction TP BF-STB Part B 8.3/issue  2003, the HMP LFG 4  provides  measurements that have direct correlation to static load test (DIN18134, BS1377, ASTM D1194/1195/1196) & Procter test (Dpr)*.

Suitable for coarse-grain  and mixed grain soils having a maximum grain size of 63mm and can be used to  determine the dynamic modulus of deformation of soil (resilience) in the  range Evd = 15...70MN/m .

The LFG 4 allows measurement on multiple layers of soil, unbound sub-base  and sub-grade during formation works or  before overlay and pavement. Deflections may be either correlated  directly to pavement or used to determine in-situ material characteristics of  the pavement foundation layers. Provided with Thermal Printer & Software for data analysis.
