401.13.4 When a Lot of asphalt pavement is determined to be statistically non -conforming
in accordance with Criteria ‘B’ of Section 401.7.4, the Division will review the plans and project records to determine if there is an acceptable explanation for this deficiency. If it is determined that a def iciency does exist, one of the following adjustments may be used. If the deficiency is less than ¾ inch, the Division may choose to accept the material at a price equal to the bid price times the ratio of the average thickness divided by the specified thi ckness. If the deficiency is ¾ inch or greater, the Division may require that an additional lift of material [specified to the nearest ¼ inch of the deficiency] be placed at the Contractor’s expense. Retesting of the overlay will be at the expense of the Contractor in accordance with MP 109.00.20.

When stone or gravel is specified in the contract, the coarse aggregate shall consist of gravel or other acceptable polish resistant aggregate, or combination thereof meeting the requirements of 703.1 through 703.3, except as amended in this subsection. When slag is specified in the contract, the coarse aggregate shall be slag which meets the requirements o f 703.3, except as amended in this subsection. Acceptable dolomite may be used alone or as a part of a coarse aggregate blend on roadways with a projected ESAL value of less than 3,000,000. On roadways with a projected ESAL value of 3,000,000 or greater, acceptable dolomite may be used only as a part of the coarse aggregate blend and shall not exceed 50% of that blend.

The total thin and elongated pieces, when tested as per MP 703.00.25, shall not exceed five percent (5%) . 402.2.2 -Superpave Mix Designs: For Superpave mix designs, the coarse aggregate or blends thereof shall have a minimum angularity requirement as specified in MP 401.02.28, Table 401.02.28C and, except fo r those carbonate rocks which may be designated as acceptable polish resistant aggregate, the portion obtained on the No. 4 (4.75 mm) sieve shall contain no more than 15 percent (15%) carbonate particles. Flat and elongated particles shall be tested in accordance with ASTM D4791 and the procedure modification referenced in MP 703.00.25 . The total flat and elongated particles, measured at a 5:1 ratio, shall not exceed ten percent (10%) by weight for all pav ements where the estimated traffic level is greater than or equal to 0.3 million ESALs. 402.3 -FINE AGGREGATE : 402.3.1 -Marshall Mix Designs: Fine aggregate shall meet the requirements of 702.3. 182 402.3.2 -Superpave Mix Designs: Fine aggregate shall meet the requirements of 702.3 along with the addition of the fine aggregate angularity and sand equivalent requirements noted in MP 401.02.28, Table 401.02.28C. 402.4 -MIXING : The skid resistant paving mix shall be type designated on the plans. 402.5 -MEASURMENT AND PAYMENT : Method of measurement and basis of payment will be in accordance with the applicable sections of Section 401. 402.6-PAY ITEM : ITEM DESCRIPTION UNIT 402001 -* “design method” Asphalt Skid Resistant Pavement, “aggregate type”, Type “mix type” Ton Sequence number “design method” shall be either Marshall or Superpave “aggregate type” shall be either stone and gravel or slag “mix type” from Table 401.4.2A or 401.4.2B
