SmartPave: Dynamic Shear Rheometer

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.
