I. Introduction
This instrument is designed and made as per test Methods of Bitumen and Bituminous Mixture for Highway Engineering andASTM D113 Standard Test Method for Ductility of Bituminous Materials.
It is suitable to determine the distance to which it will elongate before breaking when two ends of a briquet specimen of the material are pulled apart at a specified speed and at a specified temperature.
It adopts humanized design philosophy. There is no leading screw, lead rail or other components in the test trough. The sample can be easily installed in and the maximun measurement distance can reach 1.5m.
It adopts high-accuracy digital temperature controller.The resolution is 0.01℃ and accuracy is 0.1℃.
It adopts innovative transmission design. The stretching is stable and synchronous. There is no tremble and the speed is uniform.
Three specimens. Suitable to the test standard for asphalt duclility.
The specimen can return and positioning automatically after the determination.
It adopts membrane panel and LCD temperature controller. Water-proof, durable and easy to clean.
