The BPA 5 automatic Fraass breaking point tester determines the brittle behavior of bitumen at low temperature. A thin flat steel plaque, coated with the sample, is flexed under specified conditions at a descending series of temperatures until a crack occurs. BPA 5 is suitable for bitumen and in combination with the optional BPACon software it can also be used for other non-standardized research applications.

Standard methods:
EN 12593, JIS K 2207, IP 80

Application Range (depending  on cooler circuit):
approx. -45 °C to 60 °C

Benefits of BPA 5 FRAASS at Terminal

The automatic breaking point tester determines the brittle behavior of bitumen at low temperatures.The Fraass breaking point is the temperature at which the first crack appears in the coating of a thin, flat steel plaque flexed under descending temperatures.


The DDA 3 automatic ductility meter offers 3 simultaneous test places to measure the following bitumen properties:
Ductility or elongation is measured by the distance to which a sample will elongate before breaking.
Elastic recovery is measured by the recoverable strain determined after severing an elongated briquette specimen. Additive-containing bitumen will provide a significant elastomeric characteristic.
Force ductility measures tensile properties and the deformation energy.

Standard methods:
Elongation: ASTM D113, JIS K 2207, AASHTO T51, DIN 52013
Recovery: ASTM D6084, EN 13398, IP 516
Force: EN 13589, EN 13703, AASHTO T300, IP 515, IP 520

Application range:
-10 °C to 40 °C

Travel length:
150 cm

Automatic rupture detection:
above 20 mN

Benefits of DDA 3 at Terminal

The bitumen is cast into a brass mold. The briquette is then pulled apart in a water bath at a defined temperature until it ruptures. The rupture distance indicates the cohesiveness and general tensile properties of the material.
