ITEM 407.01040009-NON-TRACKING TACK COAT

DESCRIPTION

This work shall consist of preparing and treating an existing Portland cement concrete surface or asphalt pavement surface with a non-tracking tack coat in accordance with the Contract documents or as directed by the Engineer.

MATERIALS

Non-tracking tack coat shall be agitated or circulated to ensure a homogenous tack coat prior to sampling or application of material. The consistency of the non-tracking tack coat shall be appropriate for pumping and uniform application. Non-tracking tack coat shall not be diluted with water and must meet the physical requirements of the following table:

ITEM 407.01040009 – NON-TRACKING TACK COAT

The application is considered satisfactory when the material is applied uniformly with no visible evidence of streaking or ridging and the application rate is ±10% of the specified rate.

METHOD OF MEASUREMENT

The quantity to be paid for will be to the nearest whole gallon of Trackless Tack Coat asphalt emulsion for tack coat measured at 60°F. The following formula will be used to calculate material quantity at 60°F:

Volume@60°F = VolumeD x [1 - (∆T x 0.00025)] ∆T = Delivered Temperature (°F) – 60

VolumeD = Quantity Delivered (gal)

BASIS OF PAYMENT

The unit price bid per gallon for tack coat shall include the cost of furnishing all labor, materials, and equipment necessary to complete the work.

Notes: 1. All aggregate percentages are based on the total weight of the aggregates.

2. In no case shall the job mix tolerance fall outside the general limits.

3. The asphalt content is based on the total weight of the mix. When using slag aggregates in the mix, the asphalt content shall be increased accordingly, a minimum of 25 percent for an all-slag mix.

4. Use a Performance-Graded Binder (PG Binder) appropriate for the county in which the mix will be used, as specified in Table 6-4 of the Comprehensive Pavement Design Manual. The footnotes to Table 6-4 will not apply.

5. The use of conventional Hot Mix Asphalt (HMA) will be allowed under this contract if warm mix modified asphalt is not available.
