Specifications include, but are not limited to: 2.1.Dynamic Shear Rheometer – No Substitute Anton Paar Smartpave 102 or equivalent. 2.1.1. The DSR shall meet all requirements set forth in the most current versions of AASHTO T 315 “Standard Test Method for Determining the Rheological Properties of Asphalt Binder Using a Dynamic Shear Rheometer (DSR)”, ASTM D7175-08 “Test Method for Determining the Rheological Properties of Asphalt Binder Using a Dynamic Shear Rheometer”, ASTM D7405-10a “Standard Test Method for Multiple Stress Creep and Recovery (MSCR) of Asphalt Binder Using a Dynamic Shear Rheometer”, and AASHTO T 350 “Test Method for Multiple Stress Creep and Recovery (MSCR) of Asphalt Binder Using a Dynamic Shear Rheometer“ and ASTM D8189 “Standard Test Method for Tackiness of Asphalt Binders and Emulsified Asphalt Residue Using the Dynamic Shear Rheometer”. 2.1.2.In addition, the DSR shall be of research quality to fulfill current and future non-standardized testing needs as indicated below. 2.1.3.The DSR shall have an electrically commutated synchronous (EC) Motor with linear relationship between torque and current. Must control stress and strain. 2.1.4.DSR shall have a rotation (shear) torque range of 5 nNm to 200 mNm and can be upgraded to lower the torque range to 1 nNm 2.1.5.The DSR shall be supplied with all air filters, flow indicators, communication cables, hoses, and connectors necessary for operation. 2.2.Test Plates: 2.2.1. The DSR upper test plates must have a zero heat flow thermal insulator integrated into the upper plate shaft to prevent drift in temperature calibration due to changes in room temperature. 2.2.2.The DSR upper and lower test plates shall be serialized via permanently machined etching and be delivered with documentation of precise plate diameters as required by AASHTO T 315, ASTM D7175 and ASTM D8189 reporting requirements for test plate diameter. One set of 8mm and 25mm upper and lower test plates shall be provided. 2.2.3.The DSR shall utilize a precision quick connect coupling system which provides one-handed quickconnect coupling of the upper test plate to the instrument. The quick connect coupling system shall be of high precision taper design such that re-zeroing of the gap is not necessary after upper test plate removal for cleaning. Systems utilizing a screw-on mechanism or draw rod for affixing upper test plates will not be considered. 2.2.4.The DSR upper test plates must have Toolmaster chip that automatically loads all information into the software. Their must be no manually entering of the upper plates factors. 2.3.Environmental Chamber: 2.3.1.The DSR Environmental Chamber shall affect temperature control using a lower plate chamber with integrated Peltier elements for control over the temperature range of -40° to +200°C and upper hood with integrated Peltier elements for control to permit testing over the temperature range of - 30°C to +120°C. Active cooling of the upper test must be integrated in a hood or other enclosure. Cooling via conduction from the lower test plate will not be accepted. Systems providing temperature control of the upper test plate via electrical resistance heating, fluid circulator cooling, vortex chiller cooling, or LN2 cooling will not be considered. One Peltier controlled lower plate and one Peltier controlled upper hood enclosure shall be provided. 2.3.2.The DSR Environmental Chamber shall include an upper hood with integrated Peltier elements with a hold and heat position such that the DSR measuring drive with upper test plate affixed can be raised at least 75mm from the lower plate and the hood be in place around the upper test plate to maintain upper test plate temperature during lower plate cleaning and periods of disuse.
