TBT-2801E1 penetrometer is designed for the penetration test on numerous asphalt materials, such as highway bitumen, modified asphalt, liquid petroleum asphalt or residue of emulsified asphalt after evaporation material. This penetrometer also can be used to test a wide variety of food materials such as cheese, cream, butter, and yogurt.
TBT-2801F penetrometer is designed and made as per T0604-2011 penetration test for bituminous materials in JTG E20-2011 specification and test methods of bitumen and bituminous mixture for highway engineering and ASTM D5 standard test method for penetration of bituminous materials. The penetrometer is ideal to determine the penetration of bitumen at low temperature.
