Description

1.1 This work shall consist of preparing and applying one or more seal coats of bituminous material to a gravel or stone course.
This work shall also consist of a tack coat applied to a bituminous concrete surface or a Portland cement concrete surface.

Materials
2.1 Bituminous material shall be the type and grade specified or ordered and shall conform to the requirements of Section 702.

2.2 Blotter material shall be natural sand composed of hard, durable particles, free from loam, showing uniform resistance to
abrasion. Gradation shall conform to Table 520-2.

Construction Requirements

3.1 Limitations. Bituminous material shall not be applied on a wet surface, or when weather conditions would prevent the proper
application and curing of the coat. The quantities, rate of application, temperatures, and areas to be treated shall be approved before
application of bituminous material.

3.2 Equipment.
Equipment required for this work shall be as follows:

(a) A distributor shall be so designed, equipped, maintained, and operated such that bituminous material at even heat may be
applied uniformly on variable widths of surface up to 12 ft, at readily determined and controlled rates from 0.02 to 2.0
gal/yd?, with uniform pressure, and with an allowable variation from any specified rate not to exceed 0.02 gal. Distributor
equipment shall include a tachometer, pressure gauges, accurate volume measuring devices or a calibrated tank, and a
thermometer for measuring temperatures of tank contents. Distributors shall be equipped with a power unit for the pump
and with full circulation spray bars adjustable laterally and vertically. The spray bar shall contain spray nozzles providing
a fan-shaped spray pattern adjusted so the vertical axis is perpendicular to the pavement surface. The spray pattern and
spray bar height shall be adjusted to provide a uniform application of the tack coat without double coverage. The
distributor shall be equipped with a mechanical device to adjust the spray height as material is discharged to keep a
uniform height above the pavement for full coverage without overlapping. The distributor shall also be equipped with a
hand-held spray attachment for applying the material to areas inaccessible to spray bars and to fill in irregular areas to
provide full coverage. Approved sampling valves shall be installed in distributors and transport tank trucks to permit
taking representative samples of the contents. The recommended location of the sampling valve is in the rear bulkhead of
the tank roughly one-third of the height above the bottom. The inlet pipe shall project into the contained liquid as shown
in AASHTO T 40. At least 1 qt of material shall be drained off through the sampling valve and discarded before the
desired sample is taken. New sample containers will be furnished by the Engineer. To prevent the loss of solvents,
containers shall be sealed with a tight fitting cover immediately after being filled.

(b) A rotary power broom for sweeping treated surface.

(c) A steel-wheeled roller.

(d) A self-propelled pneumatic-tired roller.

{e) A sand spreader capable of spreading blotter material in sufficient quantity to prevent traffic pickup of the applied
bituminous material.

(f) A steel-brush drag of an approved type.

3.3 Preparation of Surface to be Treated.

3.3.1 Tack coat. The existing surface shall be patched and shall be free of irregularities to provide a reasonably smooth and
uniform surface to receive the treatment. Unstable corrugated areas shall be removed and replaced with suitable patching materials.

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.

3.4.1.1 A tack coat shall be applied immediately prior to placement of pavement. The rate of application of emulsified asphalt
shall be between 0.02 and 0.08 gal/yd’, based on the application table below. The Engineer may further modify the rate depending
on the relative absorbance and texture of the pavement surface.

3.5 Seal Coat.
3.5.1 When directed, a seal coat shall be applied at the rate in gallons per square yard specified on the plans or as ordered.

3.5.1.1 Bituminous material shall be applied to the width of the section to be sealed by means of a pressure distributor in a
uniform, continuous spread. When traffic is maintained, not more than one half of the width of the section shall be treated in one
application. Care shall be taken that the application of bituminous material at junctions is not in excess of the specified amount.
Excess material shall be squeegeed from the surface. Skipped areas or deficiencies shall be corrected.

3.5.1.2 When traffic is maintained, one-way traffic shall be permitted on the untreated portion of the roadbed. As soon as the
bituminous material has been absorbed by the surface and no longer picks up, traffic shall be transferred to the treated portion, and
the remaining width of the section shall be sealed.

3.5.2 Blotter material at the rate ordered shail be applied before the bitumen has set; the entire treated surface shall be dragged,
rolled and maintained. The remaining blotter material shall be removed.

3.6 Finished Appearance.

3.6.1 Any bituminous material splashed or sprayed onto exposed surfaces of curbs, sidewalks, or other masonry structures shall
be removed by sandblasting at the Contractor's expense.

Method of Measurement
4.1 Bituminous surface treatment will be measured by the ton, in accordance with 109.01, to the nearest 0.1 ton.

4.1.1 Blotter material furnished will be subsidiary.
4,2 Asphalt emulsion for tack coat will be measured by the gallon, in accordance with 109.01, to the nearest gallon.

4.2.1. The measurement will be based on a calibrated meter mounted on the distribution vehicle or calibrated tank chart. The
meter shall be calibrated at least twice per year. Measurement will be at the delivered temperature (no adjustment).

Basis of Payment
5.1 The accepted quantities of bituminous surface treatment will be paid for at the Item Bid Price per ton for bituminous material,
complete in place.
