Automatic Bitumen Penetrometer

We offers automatic bitumen penetrometer.
i---brief introduction
the instrument is designed and made as per the standards gbt4509 "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.
