Automatic Asphalt Indentation Penetrometer


TAS-2130 Automatic Indentation Penetrometer determines the resistance of an asphalt cube and cylindrical specimens to indentation when force is applied to them using a cylindrical pin in a defined period. Maximum nominal size of the aggregates should be less or equal to 16 mm.

TAS-2130 can apply a 25 N preliminary force and than 525 N total force without touching the test weights with electromechanical method acc. to TS EN 12697-20.

TAS-2130 consists of a four-columns frame combined with an assembly for force application and a stainless steel 25L water bath with drain facility, a digital control unit with immersion type heater-agitator, 50 x 0.01 mm displacement transducer with holder, calibration block, interchangeable indentor pin with 100 mm2 and 500 mm2, an adjustable mould 69mm, a metal intermediate plate and a free software.

Cube mould and the apparatus for preparing the test cubes should be ordered separately.
