Fraas Breaking Point Apparatus

The UTB-0257 Breaking Point Apparatus is used to determine the breaking point of solid and semisolid bitumen.

The Fraass Breaking Point is the temperature at which bitumen first becomes brittle, as indicated by the appearance of cracks when a thin film of bitumen on a metal plaque is cooled and flexed in accordance with specified conditions.

The apparatus consists of a bending device, a plaque made of springly stainless steel 41x20x0.15 mm, a cooling device, a thermometer IP 42 C, a plate and stand.
