Show all pagesNJDOT TEST METHODS NJDOT B-3 — SELECTING CORES FOR MAXIMUM SPECIFIC GRAVITY TESTING IN AIR VOIDS DETERMINATION A. Procedure: THE FOLLOWING NOTE IS ADDED AFTER STEP 3: NOTE: For Recore Lots and Statistical Outlier Lots, do not randomly select a core for maximum specific gravity testing. The entire core lot must be tested for maximum specific gravity. THE FOLLOWING STEP IS ADDED AFTER STEP 9: 40. If the lot has an outlier or is a recore lot, the entire lot must be tested for maximum specific gravity. Calculate air voids using each individual core maximum specific and bulk specific gravity. 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
