Compliance with Standards

The DUCTILITY TESTING MACHINE-(REFRIGERATED) from EIE 461 complies with the following national and international standards: - IS: 1208 - ASTM D 113 - ASTM D5892 - ASTM D6084 - AASHTO T51

These standards underline the machine's reliability and its adherence to globally recognized testing protocols, ensuring results are consistent, valid, and applicable across different regions and projects.

Functionality

The primary function of the machine is to measure the ductility of bituminous materials accurately. Ductility is defined as the distance in centimeters to which a standard briquette of bitumen can be stretched before the thread breaks. This operation is crucial in understanding the material's flexibility and tensile properties, which directly impact its performance in real-world applications. The following parameters are vital in this testing process:

Rate of Stretching

The briquette is stretched at a speed of 50 mm/min ± 2.5 mm/min. This controlled rate ensures uniform stress distribution and accurate measurement of ductility.

Temperature Control

The testing is carried out at a controlled temperature of 27° C ± 0.5° C. The machine features a refrigerated system to maintain this precise temperature regulation throughout the test duration, thereby minimizing temperature-related variances in test outcomes.
