GD-2801I Low-Temperature Versatile-Type Bitumen Penetrometer
Brief Introduction
- The instrument is designed and made as per the standards GB/T4509 "Test Method for Penetration of Bitumen", T0604 "Bitumen Penetration Test" in the standard JTJ052-2000 Specifications and Test Methods of Bitumen and Bituminous Mixtures for Highway Engineering and ASTM D5.
- The instrument is suitable to determine the penetration of highway bitumen, modified asphalt, as well as liquid petroleum asphalt or residue of emulsified asphalt after evaporation.
- The test condition is described as follows:The penetration of bituminous materials is expressed as the distance that a 100 g±0.05 g standard needle vertically penetrates into the sample without measurable fraction in 5 s at a constant temperature bath of 25±0.1 °C.
- It is used for evaluating the consistency of asphalt. The larger the penetration is; the thinner and softer the asphalt is.
- The instrument can also be used for inspecting industry materials such as solid granule, powder, colloid, as well as food materials such as cream, glycine, etc.
- It has been widely used in the field of food industry, highway and traffic departments and other departments.
Main technical specifications and parameters
1.Measurement range: 0 penetration~600 penetrations;
