FR-Z 075,
it is designed to find CBR values for basic and sub-basic materials used in road construction with a grain size of less than 19 mm (¾ in) and strength values for cohesive materials.
The CBR (transport ratio) experiment requires the penetration piston to apply a load to the soil sample at a defined displacement rate, measuring the amount of load and penetration at regular intervals.
The device with double column body and height adjustable upper beam has a capacity of 50 kN. Loading speed is 1.27 mm / min. Using the Up/Down buttons on the front panel, the piston’s contact distance to the sample can be quickly adjusted. At the end of the experiment, the piston for a new experiment moves upward at a speed of 5mm/min.
FR-Z 075 The CBR experimental device is supplied with the following.
- Load Ring, 50 kN
Digital compartment clock, 25×0.01 mm, with Holder
Penetration Piston
