Ductility machines are used to determine the ductility of formed asphalt/cement or semi-solid bitumen by measuring the distance of elongation before reaching the breaking point of a briquet sample, which is pulled apart at a specific speed and temperature. The H-1068 Ductility machines meet ASTM D113, D6084 and AASHTO T51, T301 and T300 when H-1021 is utilized. In the absence of any specified variations in the test method, the test procedure as outlined in these instructions may be followed.

Ductility of standard briquette moulds of bituminous material is the distance in centimeters that will stretch before breaking when tested on standard ductility test equipment. The result of this test indicates the extent to which the bituminous material samples can be pulled elastically under known conditions of temperature and speed.


The objective of this test is to measure the tensile properties of bituminous material by determining the ductility of bituminous   material. This ductility could be empirically determined by measuring the distance to which it will elongate before breaking when two ends of a briquette specimen of the material are pulled apart.


1. Ductilometer that comprises a water bath
2. Stop watch
3. Three brass briquet moulds
4. Thermometer


  i. Heat gently the bituminous material so as to facilitate flow at pouring temperature.
  ii. Pour it into standard briquet moulds (approximately total length of brass mould is 1 cm) to form standard bituminous material specimens.
  iii. The specimen moulds are cooled to room temperature for at least half an hour.
  iv. Immerse the ductility specimens in a water bath and maintain its temperature at 25C   0.5C for another 30 minutes.
  v. After the ductility specimens have attained the desired temperature, place them in a ductilometer.
  vi. Manage the ductilometer such that one end of the mould is held in a fixed...
