Ring and Ball Apparatus – Softening Point Determination of Bitumen
The Ring and Ball Apparatus is a precision testing instrument designed for determining the softening point of bitumen, asphalt, and coal tar pitch within the range of 30°C to 157°C. This method is essential for quality control in pavement construction and bituminous material testing. The apparatus follows standard test procedures where steel balls are placed over bitumen samples in brass rings, and the temperature of the bath is gradually raised. The softening point is recorded when the sample softens enough to allow the ball to drop a specified distance.
Engineered for accuracy and repeatability, this apparatus includes two square-shouldered brass test rings, steel balls, and a heat-resistant beaker, providing a complete setup for simultaneous dual testing. Designed in compliance with EN 1427 and BS 2000-58 standards, this equipment is ideal for laboratory and industrial applications.
