Softening Point Apparatus


Conforms to ASTM D36, ASTM D2398, ASTM E28, AASHTO T53, AASHTO IP198

 

The Ring and ball method Apparatus is used to determine the softening point of asphalts, pitches, tars and most resins.The softening point is the degree of temperature at which a solid substance starts to convert into a liquid state under certain specific conditions.

The softening point of asphalt is defined as the temperature at which two disks of a sample can no longer support the weight of a steel ball. As asphalt does not have a specific melting point, the rate at which it softens is extremely important. Because the softening point is needed to establish the uniformity of shipments or sources of supply, it is frequently used to classifying bitumens.

Instructions for Use

top
One of the most common ways to determine a softening point is through the use of a ring-and-ball apparatus. During this test, steel balls are placed on top of bitumen disks within a bath. As the temperature of the bath rises, the samples soften and are unable to hold the balls. The temperature at which the balls drop 25mm (1 inch) is then recorded.
