Test the asphalt-rubber binder as follows: As soon as the viscometer is leveled and the depth mark is even with the asphalt-rubber binder surface, begin rotor rotation. When using a digital viscometer, activate the continuous digital display according to the manufacturer's recommendations. Read and record the peak viscosity value (The peak measurement typically represents the viscosity of the asphalt-rubber binder; report and log that value. As the rotor continues to turn, it “drills” into the sample and spins rubber particles out of its measurement area. This may cause thinning of the material in contact with the rotor erroneously indicating a drop in the apparent viscosity of the asphalt-rubber binder) from the graduated scale labeled with the corresponding rotor number or from the digital display. After completing the first measurement, move the viscometer rotor away from the center of the sample can without removing it from the asphalt-rubber binder sample. Turn off the rotor rotation. Stir the asphalt-rubber binder sample thoroughly. Repeat Steps 1, 2, and 3. Take 3 measurements and average the results to determine the viscosity. Return the viscometer to its holder with the rotor suspended in a suitable solvent. Before using the rotor again, wipe off the solvent and dry the rotor to avoid solvent contamination of the next sample. Calculations. Some meters read in units of mPa:s (0.001 Pascal-seconds) or dPa:s (0.1 Pa-s), while others may read in centipoise (cPs) units. The conversion is 1 Pa:s = 1000 cPs. Report. Include the following items in the report: APPS > Date and time sampled. Location of asphalt-rubber binding blending plant. Test temperature and viscosity. Rotor designation. Viscometer model and serial n NJDOT R-1 —-OPERATING INERTIAL PROFILER SYSTEMS FOR EVALUATING PAVEMENT PROFILES THIS ENTIRE TEST METHOD IS CHANGED TO: A. Scope. This test method describes the procedure for operating, verifying the calibration of an ASTM E 950 Class 1 Inertial Profiler System (IPS) and testing riding surface for pavement profiles evaluation. Apparatus. Use an IPS that meets the requirements of AASHTO M 328 and ASTM E 950, Class 1 and the following: te Certify the IPS according to AASHTO R 56 at least every 2 years. If a system component is replaced, re-certify the system. Perform the certification at a site approved by

ass 1 and the following: te Certify the IPS according to AASHTO R 56 at least every 2 years. If a system component is replaced, re-certify the system. Perform the certification at a site approved by the Department. The data system provides the raw profile data in an ASCII format acceptable to the Department. The computer program uses a high-pass filter set at 300 feet and reads an ASCII or text file for computing the International Roughness Index (IRI) in inches per mile. The current version of ROADRUF, ProVal, or other Department approved pavement profile analysis software is used to compute the IRI. Procedure. Perform the following steps: le Operate the IPS according to AASHTO R 57 and ASTM E 950. 65
