Purpose:
1) DSHD-0613 Asphalt Breaking Point Tester is designed and developed as per T0613 "Asphalt Breaking Point Test (Fraass Methods)"in the Industry Standard JTJ052 Specification and Test Methods of Bitumen and Bituminous Mixture for Highway Engineering.
2) DSHD-0613 Asphalt Breaking Point Tester is used to determine Fraass Breaking Point of bituminous materials. pread a layer of asphalt thin film on a specially designed metal sheet, and place it into a insulation cylinder, which contains refrigeration device. Bend metal sheet using the handle. Lower down the temperature of asphalt thin film gradually.
3) While DSHD-0613 Asphalt Breaking Point Tester is cooled down to a certain temperature, the thin film will break under the specified bending condition. The temperature is the breaking point of asphalt.
Technical specification:
- Temperature measurement range: -30 ~100°C;
- Temperature measurement accuracy: 1 °C;
- Size of steel sheet: 41×20×0.15mm;
- The maximum distance of clamps: 44 mm;
- Height difference of base: 3.5 mm;
