immediately take an acceptance sample to test and verify that the composition meet gradation and volumetric requirements specified in Table 902.02.03-1 and Table 902.02.04-1. If 2 consecutive acceptance or quality control samples are outside the gradation or volumetric requirements specified in Table 902.02.03-1 or Table 902.02.04-1, immediately stop production and shipping. After a production stop, obtain ME approval of a plant correction plan before resuming production. Upon restarting production, do not transport mixture to the Project Limits before the results of a quality control sample from the mixture indicate that the mixture meets gradation and volumetric requirements specified in Table 902.02.03-1 and Table 902.02.04-1 and ME approval. The ME will reject mixture produced at initial restarting that does not meet gradation and volumetric requirements specified in Table 902.02.03-1 and Table 902.02.04-1. The ME will test a minimum of 1 sample per 3,500 tons for moisture, basing moisture determinations on the weight loss of an approximately 1,600 gram sample of mixture heated for 1 hour in an oven at 280 ± 5 °F. Ensure that the moisture content of the mixture at discharge from the plant does not exceed 1.0 percent.

Bulk specific gravity of the compacted mixture is determined according to AASHTO T 166. 902.02.04 Sampling and Testing THE FOLLOWING SUBSECTION IS ADDED: E. Acceptance of HMA. The Department may accept the HMA as specified in 902.02.04.A through 902.02.04.E by employing staff or an independent testing agency at the HMA plant during production. The inspector who performs the quality assurance sampling shall be certified by the Society of Asphalt Technologists of New Jersey as an Asphalt Plant Technologist, Level 2. Form “DS-8 HMA Testing Summary Report – State Aid” provided on the Local Aid Website must be utilized by the Laboratory to report their findings to the RE. Alternatively, the Department may accept the HMA by Certification of Compliance according to 106.07. SECTION 903 – CONCRETE 903.01 CEMENT THE ENTIRE SUBSECTION TEXT IS CHANGED TO: Use cement, listed on the QPL, that is either portland cement or blended hydraulic cement and conforms to the following: Portland Cement, Type I, II, and Type III ................................................................................................ ASTM C 150 Blended Hydraulic Cement, Type IS, IP, and IL ..................................................................................... ASTM C 595 Only use Type III portland cement for Class V concrete, prestressed Items, and precast Items. Use portland cement pre-blended with a maximum of 25 percent fly ash, by weight, or a maximum of 5 percent silica fume by weight, or with a maximum of 50 percent slag by weight for blended hydraulic cement Type IS or IP. Use portland cement pre-blended with a minimum of 5 percent limestone content and a maximum of 15 percent limestone content by HELEN AVE., LAWRENCE AVE., FLORENCE PL., AND LOWELL AVE., IMPROVEMENTS PROJECT Page 70 of 76
