The Swell Test Equipment is placed on top of the soil sample to enable monitoring of swelling. The swell test consists of perforated plate with adjustable stem (swell plate) dial gauge tripod and dial gauge. 


To distribute pressure water “up to 1700 kPa.” Simple, practical and extremely accurate to select tests pressure, it can also offer the possibility to further system expansions. The cell set includes a high pressure air inlet attachment, “a high accurate regulator which enables to set the work pressure and 4 valves for pressure water outlet, water and air drain.” The cell membrane enables the use of deaerated water. A suitable compressor, which can grant a pressure source, is necessary for using the air/water membrane cell. Air/Water panels are used with an interface to convert air pressure from a standard compressor into water pressure. Bladder Air/Water Cylinder. 


The Automatic Soil Compactors is designed to provide a uniform compaction of Standard, Modified and CBR specimens assuring conformity with the reference standard. The Compactor is equipped with programmable digital counter which allows machine to stop at the preset numbers of blows. The height and weight of the rammer is adjustable to suit test requirements. The drop weight is adjustable to 300 mm drop height and is also adjustable to 450 mm drop height. The rammer is circular faced with a 50 mm diameter and is adjustable to 2.5 kg. or 4.5 kg. An automatic blow pattern ensures effective compaction for each layer of soil and the rammer travels across the mould. The table rotates the mould in equal steps and the number of blows per layer can be set at the beginning of the test by the digital counter. 


The LCD graphics Data Acquisition and Controls System (DA/CS) is designed to control the machine and to process the data from linear potentiometric transducers, Load Cells, installed on the CBR machine frame. The DA/CS compatible design satisfies the ergonomic requirements for various uses. The digital graphic display allows real time Load vs. penetration graph and value readout. At the end of the test cycle the results can be stored in the large memory or to a PC by using the CBR software. Dedicated real time CBR software package is available for testing and further data processing, database management and certificate printing. Specification: •Calculates corrected CBR value at 2,5mm and 5mm •Large memory up to 100 tests •RS232 connection serial port for connecting either PC or printer for data transmission •Two analogical channels, for Load Cell Linear and potentiometer transducer 


The Dynamic Cone Penetrometer apparatus was originally developed by the TRL-UK Transport Research Laboratory. It is used for In-rapid in situ measurement of structural properties of existing road pavement constructed with unbound materials. It consists of an 8 kg weight dropping through a height of 575 mm and 60° cone having a diameter of 20 mm. DCP measurements can be made down to a depth of approximately 850 mm. Correlation’s have been established in earlier work (Van Vuuren, Klein and Van Herden, Smith and Pratt) between the TRL penetrometer and CBR (California Bearing Ratio) so that results can be interpreted and compared with CBR specifications.
