Digital Ductilometer TT-113
Digital Ductilometer TT-113
Digital Ductilometer TT-113 aligns with the ASTM D113 Standard Test Method for Ductility of Bituminous Materials. This instrument is designed to ascertain the distance of elongation before breakage occurs when two ends of a briquette specimen of the material are pulled apart at a defined speed and temperature.
The primary application of the Digital Ductilometer TT-113 is to measure the ductility of bituminous materials (asphalt), in compliance with the ASTM D113 standard. The test determines how far a standard specimen of asphalt binder can be stretched before it breaks under controlled temperature and speed. This measurement is a crucial indicator of the asphalt's cohesive and adhesive properties, which are essential for ensuring the long-term durability and crack resistance of pavement.
Key Industries
- Asphalt Production & Petroleum Refining: This is a fundamental quality control test for asphalt producers. It allows them to grade their asphalt binders and certify that they possess the required cohesive properties to perform effectively in paving applications.
- Road Construction & Paving: Paving companies and highway agencies rely on this test to ensure the material used will resist cracking and raveling under traffic loads and temperature changes.
- Civil Engineering & Materials Testing Laboratories: These labs, including Departments of Transportation (DOTs) and commercial testing firms, use the ductilometer for quality assurance and compliance testing on materials used in infrastructure projects, ensuring they meet all engineering specifications.
