The dynamic shear rheometers (DSR) SmartPave 92 and SmartPave 102 allow precise measurements on asphalt and bitumen. SmartPave 92 was specially developed for quality control measurements and routine measurements in asphalt testing laboratories. SmartPave 102 is ideal for the most demanding measurements. It is used in the research and development of asphalt and bitumen. Features such as Toolmaster™, QuickConnect, a Peltier temperature device for dry sample heating, and step-by-step instructions for measuring procedures according to AASHTO T315, AASHTO T350, AASHTO TP101, ASTM D7175, ASTM D7405 and DIN EN 14770 guarantee the most convenient operation. For measurements according to AASHTO T316, ASTM D4402 and DIN EN 13302 both instruments can be equipped with a Peltier-temperature-controlled measurement chamber for concentric cylinder geometries.

Dynamic Shear Rheometer

Industry standard Asphalt binder grade testing

Market proven worldwide, the Malvern DSR dynamic shear rheometer has been specifically designed to satisfy the demands of high throughput grade testing of Asphalt binders (bitumen), to AASHTO (American Association of State Highway and Transportation Officials) industry standards.

Overview

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.
