    2. Asphalt shall comply with INDOT Specifications for Asphalt Cement, Prime Coat, and Tack Coat.
    3. Provide hot plant mixed asphaltic concrete paving materials meeting INDOT Standard Specifications including the INDOT temperature requirements.
  3. ASPHALT
    1. Each asphalt course shall be compacted to 92% Voidless Density.
    2. Asphalt shall be placed true to profile and grade as shown in the City of Plymouth - Design Standards. Final surface deviations shall not exceed 1/8" in six feet. Proper drainage must be achieved away from the street section. Low Areas that would pond water must be replaced/repaired to the satisfaction of the City Representative.
      1. Headers and stakes should be placed to achieve the proper street profile and grade.
      2. To insure minimum pavement course thicknesses, remove all loose materials from the compacted base and minimize tire cuts in the base caused by the paver or the trucks.
    3. Apply the asphalt prime coat and tack coat as required, and in accordance with the manufacturer's recommendations and INDOT Standard Specifications.
    4. Frames and covers shall be adjusted to meet final grades.
    5. Follow the following asphalt placement guidelines:
      1. Do not accept material unless it is covered with a tarpaulin until unloaded, and unless the material has a temperature of not less than 280 degrees F.
      2. Do not commence placement of asphaltic concrete materials when the atmospheric temperature is below 50 degrees F, nor during fog, rain, or other unsuitable conditions.
      3. Spread material in a manner which requires the least amount of handling.
      4. After the material has been spread to the proper depth, roll until the surface is hard, smooth, unyielding, and true to the thickness and elevations shown on the Drawings.
      5. Roll in at least two directions until no roller marks are visible.
      6. Protect the asphalt paved surfaces from traffic until it is set and cured.
      7. Do not place a subsequent lift on placed asphalt until it is set and cured.

    3. Testing shall be performed in a manner that evaluates the project as a whole.
      1. Five (5) tests will be taken on each panel for every 1000 linear feet of panel or portion thereof.
      2. The compaction tests shall exceed the 92% Voidless Density as previously stated.
        1. If these tests do not exceed the 92% Voidless Density; the City Representative at his/her own digression based upon the performance of proper construction methods may accept the panel if:
          1. The average of the five (5) tests is greater then 92% Voidless Density, and
          2. All test values are above 90% Voidless Density.
        2. If the compaction tests do not meet the above criteria, the Department Head may accept the product upon evaluation of the construction methods and conditions. The Department Head may require a maintenance agreement with the developer.
      3. If a panel is rejected it must be repaired/replaced. If the repair or replacement does not occur, the City may reject the entire street by not receiving it into public domain. Reference: City of Plymouth - Standard Specifications A.100 - City Requirements.
