Ductility of Bituminous Materials
The measurement of the ductility of a bituminous material involves determining the distance it can elongate before breaking. This is achieved by pulling apart the two ends of a briquette specimen of the material at a specified speed and temperature. By default, the test is conducted at a temperature of 77 ± 0.9°F (25 ± 0.5°C) and a speed of 5 cm/min ± 5.0%. However, if the test is performed at different temperatures, the speed should be explicitly stated.
The manual ductilometer is comprised of the following components:
• The structure is constructed entirely from stainless steel.
• The front panel features manual controls for carriage movement, a main switch, and a temperature thermoregulator.
• The internal bath is made of stainless steel and has rounded edges for easy cleaning.
• It includes an atmospheric drainage system with a stopcock.
• Low voltage circulating pumps ensure uniformity in the bath temperature, and stainless steel immersion heaters are also present.
• The carriage head has three places with a brake, and there is a pointer to facilitate identifying the breaking point.
• A 1500 mm ruler with a 1mm resolution is provided.
• Power Supply: The manual ductilometer can be powered by either 220 Vac or 115 Vac, and it is compatible with both 50 Hz and 60 Hz frequencies.
The refrigerated manual ductilometer is constructed with the following features:
• The structure is entirely made of stainless steel.
• The front panel includes manual controls for carriage movement, a main switch, and a temperature thermoregulator.
• The refrigeration system uses a motor compressor that is free of CFC gas, allowing for test temperatures up to +5°C.
• The internal bath is made of stainless steel and has round edges for easy cleaning.
• It includes an atmospheric drainage system with a stopcock.
• The ductilometer is equipped with low-voltage circulating pumps to ensure uniformity in the bath temperature, along with stainless steel immersion heaters.
• The carriage head has three places and is equipped with a brake, along with a pointer that facilitates identifying the breakpoint.
• It comes with a 1500 mm ruler with a resolution of 1mm.
• The frame cover has a full-length inspection window equipped with anti-overturn security features.
• The power supply options are 220 or 115 Vac, compatible with both 50 Hz and 60 Hz frequencies.
