The Malvern DSR asphalt rheometer is proven as the benchmark system for Quality Control testing to industry standards in regulated markets worldwide.

• Developed in close association with industry researchers to meet all instrument criteria and test protocols of AASHTO (American Association of State Highway and Transportation Officials) standards.
• Compact, integrated unit designed specifically for ease of use and robustness in high throughput Asphalt binder (bitumen) test environments.
• Air bearing and mechanical bearing options to provide robust and cost-effective measurement platforms for any industrial laboratory or remote field testing location.
• Integrated fluid immersion cell specifically based on patented principle for temperature control of highly thermally-sensitive asphalt or bitumen samples.
• Rapid thermal equilibration and elimination of thermal gradients in the sample - essential for consistent and reliable data, and optimized sample throughput.
• Excellent temperature stability and accuracy, with a resolution of ± 0.01°C.
• Rapid, robust manual gap set, with pre-set gaps for AASHTO tests for simplicity of use.
• Active thermal mode to ensure constant gap is maintained for all temperature test points.
• Plate measuring systems (both upper and lower plates) designed to comply with industry standards (AASHTO).
• Dedicated AASHTO specification QC software package (TruGrade) available.
