SECTION 410

The edges of existing pavements that are to be adjacent to new pavement shall be cleaned to permit the adhesion of bituminous
materials.

3.4 Application of Bituminous Material.

3.4.1 Tack coat. Bituminous material shall be uniformly applied with an approved applicator. When ordered, a pressure
distributor shall be used. The tack coat shall be applied in such a manner as to offer the least inconvenience to traffic and to permit
one-way traffic without pickup or tracking of the bituminous material.

SECTION 403 -- HOT BITUMINOUS PAVEMENT

Description

1.1. This work shall consist of constructing one or more courses of bituminous pavement on a prepared base as shown on the
plans or as ordered. The methods may be classified as hand or machine.

SECTION 401
Appendix A

NHDOT Test Procedure B-7

Sampling Bituminous Paving Mixtures For Acceptance Testing

Sample shall be taken behind the paver after placement and before compaction.
Sample location is randomly selected by the Contract Administrator.

When paving over aggregate base course or cold planed surface, use a rectangular metal plate no less than 12” each side.
Center plate on sample location.

After paver passes over plate, measure back to sample location.
Locate the edges of the plate.

SECTION 401

5.6.3 Pay adjustment, Hot Bituminous Pavement QC/QA Ttems. The pay adjustment for gradation, cross slope,
thickness, asphalt binder content, in place air voids, and ride quality (made up of the sum of all sublots) will be applied to item
1010.3. Pay adjustments may be applied at the end of each month based on all available test results for each lot.

5.7 The accepted quantity of joint adhesive of type specified will be paid for at the Contract unit price per linear foot complete
in place.

SECTION 401

Paving operations shall not resume until the Engineer determines that material meeting the Contract requirements can be

produced. Corrective action will be considered acceptable by the Engineer if the pay factor for the failing property increases. If

it is determined that the resumption of production involves a significant change to the production process, the current lot will be

terminated and a new lot will begin.
3.17.3.6.3 Remeasure and Retest. All requests to the Engineer to remeasure and retest a sublot shall be in writing.
