REPLACE THE FIRST PARAGRAPH OF THIS SECTION WITH THE FOLLOWING: Test Strip. Construct a test strip for each HMA mix for contracts with more than a total of 5,500 tons of HMA. For HMA HIGH RAP, construct the test strip at least 14 days prior to production. Test strips are not necessary for temporary pavement. Ensure that the tack coat or prime coat has been placed as specified in 401.03.05 and 401.03.06, before placing HMA. Transport and deliver, spread and grade, and compact as specified in 401.03.07.D, 401.03.07.E, and 401.03.07.F, respectively, and according to the approved paving plan. Construct a test strip for the first 700 to 1,200 square yards placed for each job mix formula. If the paving lot area is less than 700 square yards, the District Local Aid Office may waive the coring requirements. While constructing the test strip, record the following information and submit to the RE: D. Transportation and Delivery of HMA. THE SECOND SENTENCE OF THE FIRST PARAGRAPH IS CHANGED TO: Do not allow trucks to leave the plant within 1 hour of sunset unless lighting for night operations is provided as specified in 108.06. THE SECOND PARAGRAPH IS CHANGED TO: Ensure that weigh tickets are signed and sealed by a certified weighmaster. Individual weigh tickets do not need to be signed and sealed if using an automated batching plant or automated drum plant. THE FOURTH PARAGRAPH IS CHANGED TO: When using an automated batching plant, obtain weigh tickets from the printer used in conjunction with an automated batching and mixing system. Ensure the printed ticket shows the individual weights of the various components of the HMA in a batch, the total weight of each batch, and the sum of all batch weights in the truckload. If using an automated batching plant or automated drum plant, at the completion of each day’s work, provide certification from the weighmaster that the total net weight supplied was correct. E. Spreading and Grading. G. Opening to Traffic. THE FOLLOWING IS ADDED AFTER THE LAST PARAGRAPH: Ensure that RPMs are installed and rumble strips are constructed within 14 days of opening each day’s surface paving to traffic. H. Air Void Requirements FOR LOCAL AID PROJECTS, THIS SUBSECTION IS REPLACED BY THE FOLLOWING. Pavement lots are defined as approximately 15,000 square yards of pavement in

paving to traffic. H. Air Void Requirements FOR LOCAL AID PROJECTS, THIS SUBSECTION IS REPLACED BY THE FOLLOWING. Pavement lots are defined as approximately 15,000 square yards of pavement in Surface area. If pavement lot area is less than 5000 square yards, the Local Aid District Office may waive the air voids requirements. The RE will designate an independent testing agency (Laboratory) to perform the quality assurance sampling, testing and analysis. The Laboratory is required to be accredited by the AASHTO Accreditation Program (www.amrl.net). The Laboratory’s accreditation must include AASHTO T 166 and AASHTO T 209. The Laboratory Technician 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. The Laboratory will determine air voids from 5 (Five) 6 inch diameter cores taken from each lot in random locations within the traveled way and at least one core in each travel lane. The HMA Core Sampling Plan form provided on the Local Aid Website must be utilized by the Laboratory to determine the random locations of the cores. The Laboratory may rerun the random location functions on the HMA Core Sampling Plan form to resolve any conflicts generated by the HMA Core Sampling Plan form and physical limitations of the HMA lot, such as utility conflicts, or the specifications HELEN AVE., LAWRENCE AVE., FLORENCE PL., AND LOWELL AVE., IMPROVEMENTS PROJECT Page 42 of 76
