Compression Testing

TuffTrak®XL has been subjected to a compressive force test at the National Physical Laboratory (NPL), UK using a circular steel platen (surface area 535 sq cm). The platen test equates to a point load test as required by BS EN 124: 1994. Samples were compressed in the NPL 12 MN hydraulic test machine. Tests were carried out under laboratory conditions with the temperature controlled to 20°C  +/-1°C and relative humidity controlled to 50%  +/- 5%.

 

 

 

 

 

 

 

Please note that testing is undertaken carried out with mat samples placed on a solid substrate, therefore, data cannot be interpreted for non-solid or very soft ground conditions. During testing the TuffTrak®XL samples resisted breakage and splitting with progressive recovery of the materials to their original state.

 

Finite Elemental Anaylsis

FEA was undertaken to calculate deflection for different California Bearing Ratio (CBR) values at various loading conditions applied to a 508 x 254mm foot print area at the center of the mat. 

It should be noted that these results are from a computer simulation. Deflection depends on the various input parameters, mat material and material properties, mat thickness and width, operation ground conditions and environmental temperature.
