Application: The softening point is a fundamental property of asphalt.
Parameters:
1.Measurment temperature accuracy: ±0.1℃
2.Automatically increase of temperature per minute: 5℃
3.Timer accuracy: 1S
4.Steel ball weight: 3.50±0.05g, diameter: 9.50mm
5.Tempurature display: 0.02℃
6.Water in the beaker is agitated by magnetic stirrer
7. The test is performed in duplicate under closely controlled conditions
8. Temperature control: Water is used as the bath  medium for binders with softening points below 80℃. Above this temperature glycerol is used in place of water.
