Bitumen Direct Tensile Testing Machine DB–20–100

In the laboratory, to determine an index of bitumen adhesion, they measure the amount of bitumen’s plasticity; the more the bitumen is adherent, the stickier it is. Bitumen ductility properties are the incremental length of a bitumen specimen in centimeters drawn at a standard rate (at a specified speed and at a specified temperature) to reach rupture or discontinuity. The length of the specimen just prior to tearing in centimeters is called ductility or stiffness.

 

Bitumen hardness is one of the factors affecting the swelling properties. That is, the harder and more brittle the bitumen is, the less its pungency and vice versa. Therefore, it should be kept in mind that if bitumen is used in a cold environment, it has a good sealing effect to prevent cracking in the asphalt. We know that as a result of vehicles passing through the road, there are tensions in the asphalt that cause slight movements in the asphalt bitumen, and if bitumen cannot tolerate these movements, especially in the cold season, one should expect To have cracks in the asphalt.

Temperature is another factor that can affect the bitumen properties of bitumen so that the bitumen property of any body is carried out at a particular temperature and that the bitumen is resistant to changes in temperature that cause it to expand and shrink, It should have a good stinging effect.

Properties:

• Lintel DB-20-100 provides automatic testing of bitumen samples for tensile strength (ductility), elasticity, strain energy, testing of plastics and polymers for tensile strength.

• Tester provides the set temperature in the test zone due to the built-in thermocriostat from -10 to +40°C.

• Tester allows testing from 1 to 3 samples with a maximum breaking force of up to 30 kg per sample.

• Automatic carriage movement at a set speed.

• Built-in pump for mixing the bath coolant and a modern cooling system ensure a minimum temperature gradient in different parts of the bath.

• Test logging provides storage of up to 100 test results and 30 sample loading schedules.

• Memorization of the tensile value and the sample number in automatic mode by the drop in the tension force or by pressing the remote button for fixing the sample rupture by the operator.

• Possibility of checking the readings of the bath temperature sensor with an exemplary thermometer.

• The color touch screen makes it easy to learn and use the device on a daily basis.
