THE FOLLOWING TEST METHODS ARE ADDED: NJDOT B-10 — OVERLAY TEST FOR DETERMINING CRACK RESISTANCE OF HMA A. Scope. This test method is used to determine the susceptibility of HMA specimens to fatigue or reflective cracking. This test method measures the number of cycles to failure. B. Apparatus. Use the following apparatus: ile 10. 11. 42: Overlay Tester. An electro-hydraulic system that applies repeated direct tension loads to specimens. The machine features two blocks, one is fixed and the other slides horizontally. The device automatically measures and records a time history of load versus displacement every 0.1 sec at a selected test temperature. The sliding block applies tension in a cyclic triangular waveform to a constant maximum displacement of 0.06 cm (0.025 in.). This sliding block reaches the maximum displacement and then returns to its initial position in 10 sec. (one cycle). Temperature Control System. The temperature chamber must be capable of controlling the test temperature with a range of 32 to 95 °F (0 to 35 °C). Measurement System. Fully automated data acquisition and test control system. Load, displacement, and temperature are simultaneously recorded every 0.1 sec. Linear Variable Differential Transducer (LVDT). Used to measure the horizontal displacement of the specimen (+/- 0.25 in.). Refer to manufacturer for equipment accuracy for LVDT. Electronic Load Cell. Used to measure the load resulting from the displacement (5000 Ib capatownship). Refer to manufacturer for equipment accuracy for load cell. Specimen Mounting System. Used two stainless steel base plates to restrict shifting of the specimen during testing. The mounting jig holds the two stainless steel base plates for specimen preparation. Cutting Template. Two Part Epoxy. Two

less steel base plates to restrict shifting of the specimen during testing. The mounting jig holds the two stainless steel base plates for specimen preparation. Cutting Template. Two Part Epoxy. Two part epoxy with a minimum 24 hour tensile strength of 600 psi (4.1 MPa) and 24 hour shear strength of 2,000 psi (13.8 MPa). 10 Ib weight (4.5 kg). Used to place on top of specimens while being glued to specimen platens. ¥, inch Width Adhesive Tape. Placed over gap in plates to prevent the epoxy from bonding the plates together. Paint or Permanent Marker. Used to outline specimens on platens for placement of epoxy. 3/8-in. Socket Drive Handle with a 3-in. (7.6 cm) extension. 60

Procedure. Perform the following steps: 1. Sample Preparation. a. Laboratory Molded Specimens - Use cylindrical specimens that have been compacted using the gyratory compactor (AASHTO T 312). Specimen diameter must be 6 inches (150 mm) and a specimen height must be 4.5 inches +/- 0.2 inches (115 +/- 5 mm). Note 1 - Experience has shown that molded laboratory specimens of a known density usually result in a greater density (or lower air voids) after being trimmed. Therefore, it is recommended that the laboratory technician produce molded specimens with an air void level slightly higher than the targeted trimmed specimen. Determine the density of the final trimmed specimen in accordance with AASHTO T 166. Core Specimens — Specimen diameter must be 6 inches +/- 0.1 inch (150 mm +/- 2 mm). Determine the density of the final trimmed specimen in accordance with AASHTO T166. 2. Trimming of Cylindrical Specimen. Before starting, refer to the sawing device manufacturer's instructions for cutting specimens. Place the cutting template on the top surface of the laboratory molded specimen or roadway core. Trace the location of the first two cuts by drawing lines using paint or a permanent maker along the sides of the cutting template. Trim the specimen ends by cutting the specimen perpendicular to the top surface following the traced lines. Discard specimen ends. Trim off the top and bottom of the specimen to produce a sample with a height of (1.5 inches +/- 0.02 inches (38 mm +/- 0.5 mm). Measure the density of the trimmed specimen in accordance with AASHTO T 166. If the specimen does not meet the density requirement as specified for performance testing for the mix being tested, then discard it and prepare a new specimen. Air dry the trimmed specimen to constant mass, where constant mass is defined as the weight of the trimmed specimen not changing by more than 0.05% in a 2 hour interval. 3. Mounting Trimmed Specimen to Base Plates (Platens). a. Mount and secure the base plates (platens) to the mounting jig. Cut'a piece of adhesive tape approximately 4.0 inches (102 mm) in length. Center and place the piece of tape over the gap between the base plates. Prepare the epoxy following manufacturer's instructions. Cover a majority of the base plates (platens) with epoxy, including the tape. Glue the trimmed specimen to the base plates. Place a 10 lb (4.5 kg)

re the epoxy following manufacturer's instructions. Cover a majority of the base plates (platens) with epoxy, including the tape. Glue the trimmed specimen to the base plates. Place a 10 lb (4.5 kg) weight on top of the glued specimen to ensure full contact of the trimmed specimen to the base plates. Allow the epoxy to cure for the time recommended by the manufacturer. Remove the weight from the specimen after the epoxy has cured. Turn over the glued specimen so the bottom of the base plates faces upward. Using a hacksaw, cut a notch through the epoxy which can be seen through the gap in the base plates. The notch should be cut as evenly as possible and should just begin to reach the specimen underneath the epoxy. Great care should be taken not to cut more than 1/16 inch (1.58 mm) into the specimen. Place the test sample assembly in the Overlay Tester's environmental chamber for a minimum of 1 hour before testing. 4. Start Testing Device. Please refer to manufacturer's equipment manual prior to operating equipment. 61

c. Turn on the Overlay Tester. Turn on the computer and wait to ensure communication between the computer and the Overlay Tester occurs. Turn on the hydraulic pump using the Overlay Tester’s software. Allow the pump to warm up for a minimum of 20 minutes. Turn the machine to load control mode to mount the sample assembly. 5, Mounting Specimen Assembly to Testing Device. Enter the required test information into the Overlay Tester software for the specimen to be tested. a. Mount the specimen assembly onto the machine according to the manufacturer's instructions and the following procedural steps. 4. Clean the bottom of the base plates and the top of the testing machine blocks before placing the specimen assembly into the blocks. If all four surfaces are not clean, damage may occur to the machine, the specimen, or the base plates when tightening the base plates. 2. Apply 15 Ib-in of torque for each screw when fastening the base plates to the machine. 6. Testing Specimen. a. b. c, Perform testing at a constant temperature recommended by the New Jersey Department of Transportation for the mixture in question. This is typically either 59 °F (15 °C) or 77 °F (25 *C); Note 3 — Ensure the trimmed specimen has also reached the constant temperature required. Start the test by enabling the start button on the computer control program. Perform testing until a 93% reduction or more of the maximum load measured from the first opening cycle occurs. If 93% is not reached, run the test until a minimum of 1,200 cycles. After the test is complete, remove the specimen assembly from the Overlay Tester machine blocks. D. Report. Include the following items in the report: ENO son> Date and time molded or cored. NJDOT mixture identification. Trimmed specimen density. Starting Load. Final Load. Percent decline (or reduction) in Load. Number of cycles until failure. Test Temperature NJDOT B-11- DETERMINING GRADATION OF CRUMB RUBBER FOR ASPHALT MODIFICATION A. Scope. This method is used to determine the gradation of the crumb rubber for asphalt-rubber binder B. Apparatus. Use the following apparatus: Pe Oven capable of maintaining a temperature of 140 + 10 °F for drying sample to a constant weight. Rubber balls having a weight of 8.5 + 0.5 grams, a diameter of 24.5 + 0.5mm, and a Shore Durometer “A” hardness of 50 + 5 per ASTM Designation D 224 No. 8,

°F for drying sample to a constant weight. Rubber balls having a weight of 8.5 + 0.5 grams, a diameter of 24.5 + 0.5mm, and a Shore Durometer “A” hardness of 50 + 5 per ASTM Designation D 224 No. 8, 16, 30, 50, 100, and 200 sieves conforming to AASHTO M 92. Mechanical sieve shaker conforming to AASHTO T 27. Balance conforming to AASHTO M 231 and having a minimum capatownship of 100 grams with a precision of 0.1 gram. 62

C. Procedure. The crumb rubber for asphalt rubber binder is required to conform to the gradations specified below when tested in accordance with ASTM Designation C 136 except as follows: 1, 2. Obtain 100 + 5 grams from the crumb rubber sample and dry to a constant weight at a temperature of not less than 135 °F nor more than 145 °F and record the dry sample weight. Place the crumb rubber sample and 5.0 grams of talc in a one pint jar, then shake it by hand for a minimum of one minute to mix the crumb rubber and the talc. Continue shaking or open the jar and stir until the particle agglomerates and clumps are broken and the talc is uniformly mixed. Place one rubber ball on each sieve. After sieving the combined material for 10 + 1 minutes, disassemble the sieves. Brush remaining material adhering to the bottom of a sieve into the next finer sieve. Weigh and record the weight of the material retained on the No. 8 sieve and leave this material (do not discard) on the scale or balance. Ensure that observed fabric balls remain on the scale or balance and are placed together on the side of the scale or balance to prevent the fabric balls from being covered or disturbed when placing the material from finer sieves on to the scale or balance. Add the material retained on the next finer sieve (No. 16 sieve) to the scale or balance. Weigh and record that weight as the accumulative weight retained on that sieve (No. 16 sieve). Continue weighing and recording the accumulated weights retained on the remaining sieves until the accumulated weight retained in the pan has been determined. Before discarding the crumb rubber sample, separately weigh and record the total weight of the fabric balls in the sample. Determine the weight of material passing the No. 200 sieve (or weight retained in the pan) by subtracting the accumulated weight retained on the No. 200 sieve from the accumulated retained weight in the pan. If the material passing the No. 200 sieve (or weight retained in the pan) has a weight of 5 grams or less, cross out the recorded number for the accumulated weight retained in the pan and copy the number recorded for the accumulated weight retained on the No. 200 sieve and record that number (next to the crossed out number) as the accumulated weight retained in the pan. If the material passing the No. 200 sieve (or weight retained in the pan) has a weight greater
