AD0113-500 - Computer controlled ductility  machine 50 cm (ASTM D113)

The ductility of a bituminous material is measured by the distance to which it will elongate before breaking when two ends of a briquet specimen of the material of a given form are pulled apart, at a specified speed, while immersed in a bath at a known temperature.

Lately, it has become very important to measure also the resistance opposed by the specimen to the elongation.
The apparatus consists of a bath where the liquid media is automatically maintained at a desired temperature in the range from 0 to 40 °C (thanks to a built-in cooling compressor) with an electrically powered tractor to pull apart at an adjustable speed the two ends of two briquet specimens: a load cell records continuously the force applied to the briquets transmitting them plus the bath temperature and the carriage speed to a PC through the RS-232 serial interface: a data acquisition software permits to display data on graphs, store them on the hard-disk and obtain printer reports.

Technical details:

ASTM D 113, D 5976 - IP 32 - ISO 1208 – EN 13398, 13589, 13703

The ductility test gives a measure of adhesive property of bitumen and its ability to stretch.
