Method of measurement and basis of payment.

Asphaltic concrete pavement shall comply and be constructed in accordance with:

WisDOT 450, General Requirements for Asphaltic Surface

WisDOT 455, Asphaltic Materials

WisDOT 460, Hot Mix Asphalt Pavement (HMA)

ALLOWANCES

If so stated in the specification “Allowances”, installation testing will be paid as an allowance. All other testing will be incidental to the Work.

If there is no reference in the specification section to “Allowances”, then testing costs will be incidental to other Work items.

SUBMITTALS

Action Submittals:

Submit two (2) copies of each asphaltic concrete mix design proposed for the project.

Informational Submittals:

Submit two (2) copies of the results of quality control testing.

Submit daily one (1) copy of weight tickets showing the net weight for each truckload of asphalt delivered and placed. Provide gross, tare, and net weights as well as date, time, ticket number, project, and mix type.

QUALITY ASSURANCE

Testing:

Obtain an independent testing laboratory approved by the Owner to provide quality control testing.

Testing agency shall perform a minimum of one density test for every 1,500 square yards of each layer of pavement placed or fraction thereof.

Retests are required within testing areas not meeting minimum density requirements.

If density testing results are below minimum requirements, submit proposed corrective action to Engineer.

FIELD OR SITE CONDITIONS

Place asphaltic mixture only on a prepared, firm, and compacted base, foundation layer, or existing pavement substantially surface-dry and free from loose and foreign material. Do not place pavement over frozen subgrade or base, when roadbed is unstable or during rain or snow.

Cold Weather Paving Remove Subsections 450.3.2.1.1(1) of the State Specifications and replace with the following:

Asphaltic pavement shall not be placed when the air temperature in the shade and away from artificial heat sources is less than 36 ̊ F. If Engineer allows placing asphaltic mixtures below the specified minimum temperature, either at the Contractor’s request or to complete the Work to the stage the contract requires, the Work will be performed at the Contractor’s risk. Final inspection of the asphaltic concrete pavement will be deferred until May of the following year. Before final acceptance of the Work, restore all pavement damage or defects the Engineer attributes to temperature or other weather conditions. Repair or replace areas of pavement as identified by the Engineer.

Wet Weather Conditions In the event of sudden or impending rain, material in transit will be permitted to be laid at the Contractor’s risk providing the pavement is free of standing water and the proper temperature of the delivered asphalt material is maintained. Approval to unload the trucks in transit shall in no way relax the requirements of quality, density, or smoothness of the asphalt being placed.

PRODUCTS

Aggregate in the pavement mix shall conform to Section 460 of WisDOT “State Specifications”, and comply with the minimum layer thicknesses as listed below:

Minimum Layer

Pavement Mix Design Prior to beginning construction, submit copies of the State approved design mixes for materials proposed to be used on this project.
