the written request, submit an Extended- Season Paving Plan on Form CS -413ES that addresses quality control operations in detail. The plan must address steps at the plant and in the field to ensure that a quality product will be delivered and constructed. Do not commence paving during the extended- season until the Representative reviews the Extended- Season Paving Plan. An extension of the paving season will be granted in writing by the District Executive with the following additional requirements:

• For all PG 64E-22 wearing and binder courses, >10 million ESALs wearing courses, 4.75 mm wearing courses, or other wearing courses placed at compacted depths less than 1.5 inches, paving may occur April 1 to November 15.

• For all other courses, paving may occur March 1 to December 15.

• Density acceptance will be by pavement cores, regardless of quantity, for mixtures placed at the minimum compacted depths in Table G. For pavements not meeting the requirements for pavement cores, density acceptance will be by optimum- rolling pattern. For non-RPS pavements , the Representative may waive the pavement core requirement at their sole discretion provided the contractor’s quality control efforts give confidence that optimum density has been achieved throughout the course.

• Utilize a Material Transfer Vehicle (MTV) as specified in Section 108.05(c)5 on any day when the paving length will exceed 1,500 linear feet, unless the Representative determines the MTV to be infeasible for the location.

• Use an approved asphalt JMF, according to the temperature restrictions specified in Section 4 13, Table A.

• Do not ship material to the project until the Representative on the project releases the shipment.

• At least five days before extended- season paving, schedule an extended- season preplacement meeting with the Representative to review, at a minimum, the details of the Extended- Season Paving Plan.

• If the Representative determines that the Extended- Season Paving Plan is not being followed, stop paving operations, modify processes to comply with the Extended- Season Paving Plan, and communicate process modifications to the Representative. Do not resume paving operations until the Representative authorizes paving operations to continue.

• Within 24 hours of paving completion, provide Form CS -413EQC to the Representative with all documentation and measurements associated with the extended- season paving operations outlined in the Extended- Season Paving Plan. Payment will not be made until the documentation is received.

• Paving work completed during the fall portion of the Extended- Season will be subject to a spring eva
