Automatic Penetrometer
This automatic 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. It is used to determine the penetration of pavement petroleum asphalt, modified asphalt, liquid petroleum asphalt and emulsified asphalt. It is also suitable to test solid particle, powder, colloid and raw-food materials such as cheese, glycine, butter, cream and leavening.
The instrument is suitable to determine the penetration of asphalt, paraffin and grease.
Needle penetration is defined as the specified temperature and time, with a certain quality of the standard needle vertical penetration into the depth of the asphalt specimen, to 0.1mm. The standard test conditions for the temperature of 25 ºC, load 100g, penetration time of 5 s. Needle penetration is the degree of asphalt hardness and softness and consistency of asphalt, resistance to shear damage, reflecting the relative viscosity of asphalt in a certain condition of the index. Needle penetration index reflects the temperature sensitivity of asphalt, but also directly related to the asphalt mixture shear resistance and high temperature performance.

- This Bitumen Automatic penetrometer adopts high-precision temperature controller, easy to set the temperature and high precision of temperature control.
- This Bitumen Automatic penetrometer is equipped with cold light source and magnifying glass, which is convenient to use and operate.
- This Bitumen Automatic penetrometer is equipped with needle penetration display, stable and accurate data, easy to observe.
- The instrument has the function of coarse and fine adjustment of lifting frame, which is convenient for the needle tip to align with the specimen plane.
- ASTM D5 refers to a specific standard test method published by ASTM International (formerly known as the American Society for Testing and Materials). ASTM D5 is titled "Standard Test Method for Penetration of Bituminous Materials" and is commonly used to determine the consistency or hardness of bituminous materials, such as asphalt or bitumen.
- The test involves measuring the depth in tenths of a millimeter to which a standard needle penetrates a sample of the bituminous material under specified conditions of time, temperature, and applied force. The penetration value obtained from the test is an indicator of the consistency or hardness of the material and can be used to classify and compare different types of bituminous materials.
- ASTM D5 provides a standardized procedure for conducting the penetration test, ensuring consistent and reliable results across different laboratories and testing facilities. It is frequently referenced in the construction and paving industry to assess the quality and performance characteristics of bituminous materials used in various applications.
