The Engineer waives this specification if the supplier is a Quality Supplier as defined by the Department's <br /> "Certification Program for Suppliers of Asphalt." <br /> C. The Department allows ASTM D 5546 instead of AASHTO T 44 <br /> d• The Engineer waives this specification if the supplier certifies the asphalt binder can be adequately pumped <br /> and mixed at temperatures meeting applicable safety standards. <br /> e. Test temperature is the temperature at which G*/sin(delta)is 2.2 kPa. A graph of log G*/sin(delta)plotted <br /> against temperature may be used to determine the test temperature when G*/sin(delta)is 2.2 kPa. A graph of <br /> (delta)versus temperature may be used to determine delta at the temperature when G*/sin(delta)is 2.2 kPa. <br /> The Engineer also accepts direct measurement of(delta)at the temperature when G*/sin(delta)is 2.2 kPa. <br /> f. Tests without a force ductility clamp may be performed. <br /> 9. "PAW means Pressurized Aging Vessel. <br /> SAMPLING <br /> • Provide a sampling device in the asphalt feed line connecting the plant storage tanks to the asphalt weighing system <br /> or spray bar. Make the sampling device accessible between 600 and 750 mm above the platform. Provide a receptacle for <br /> flushing the sampling device. <br /> • Include with the sampling device a valve: <br /> 1.
