Determination of penetration of pavement petroleum asphalt, modified asphalt, liquid petroleum asphalt and emulsified asphalt

This instrument 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. It can be widely used in food industry, highway engineering and other industrial fields.


1. The needle holder is designed novelly. It can be moved vertically and adjusted roughly and finely without measurable frication.

2. It adopts novel heating design. The heating and temperature measuring device are separated from water bath, easy to operate.

3. Equipped with automatic temperature controller and high accuracy temperature sensor, the temperature can be set conveniently and controlled precisly.

4. It adopts newly designed digital meter. The measuring data is stable and reliable.
