Analysis Instrument for Asphalt Testing

Streamlined Pavement Quality Assurance with the Analysis Instrument for Asphalt Testing

Introduction
Quality assurance of asphalt pavement materials demands rapid, accurate testing on site and in the laboratory. The Analysis Instrument for Asphalt Testing by Changsha Friend Experimental Analysis Instrument Co., Ltd. brings key tests—penetration, softening point, and ductility—into a compact benchtop unit.

Core Tests

• Penetration Test: A digital needle-penetration module measures binder softness at 25 °C using a 100 g needle over 5 seconds, with ±0.1 mm resolution.

• Softening Point (Ring & Ball): An automated heating block melts binder samples under a ring/ball assembly, detecting deformation temperature per standard slope rates.

• Ductility: A motorized pulling apparatus stretches a binder sample at 5 cm/min in a 25 °C bath until break, recording elongation in centimeters.

Design and Automation

• Single-Button Test Sequencing: Operators select test protocols, and the instrument executes temperature profiling, timing, and data capture.

• Integrated Safety Guard: Transparent enclosure shields users from hot surfaces and flying fragments.

• On-Screen Graphical Outputs: Real-time plots of penetration depth, softening curves, and ductility elongation assist immediate judgment.

Applications
Municipal labs, highway contractors, and asphalt binder suppliers rely on these traditional tests to ensure binder grades meet climate-specific requirements and tender specifications.

Best Practices
– Use fresh distilled water in the ductility bath and replace weekly.
– Level the penetration plate and confirm needle alignment before each test.
– Check softening-point ring clearance to avoid leakage.

This compact asphalt testing instrument speeds routine QA workflows, ensures compliance with national standards, and reduces bench space requirements.
