A special accelerometer is installed in a rammer which is made in accordance with JIS A1210.
The rammer of which weight is 4.5kg is ready to fall freely from 45cm height down to compacted road bed or road foundation in order to measure impact acceleration value. The measured value is immediately indicated in its digital indicator. The stronger the foundation, the larger acceleration value is indicated. The weaker the foundation, the smaller value is indicated.
