3. If the hole continues to take grout at a pumping rate not exceeding the specified flow and pressure the mix ratio shall be changed to 3:1 (w:c). If the majority of the holes accept the 3:1 without signs of slowdown in the rate of take, holes in that stage or location may be started with a 3:1 instead of the 5:1 mix. A change to a different location or stage may require a return to the 5:1 starter mix.

4. Grout mixes shall be thickened from 5:1 to 3:1 to 2:1 to 1:1 after which sand and/or fly ash shall be added to the mix in a graduated manner (5:5:1S, 5:5:2S, etc.). The water- cement ratio shall not be less than one.

Flush the surface with water, when necessary to achieve a clean surface, only when directed by the Contracting Officer; allow the surface to dry after flushing

ASPHALT SURFACE TREATMENT 027860 - 7

3.2 APPLICATION OF FIRST COURSE

A. Bituminous Material

1. Apply bituminous material by means of a bituminous distributor at the temperature specified in paragraph APPLICATION TEMPERATURE OF MATERIALS below or as directed; and within the limits specified in paragraph QUANTITY LIMITS in PART 1.

Apply bituminous material in such a manner that uniform distribution is obtained over all surfaces treated. Unless the distributor is equipped to obtain a satisfactory result at the junction of previous and subsequent applications, building paper shall be spread on the surface for a sufficient distance back from the ends of each application so that flow through the sprays may be started and stopped on the paper in order that allow sprays will operate at full force on the surface treated. Immediately after application, remove and destroy the building paper. Areas inaccessible to the distributor shall be properly treated with bituminous material using the hose attachment. Protect adjacent buildings, structured, and trees to prevent their being spattered or marred.

B. Spreading of Aggregate

1. Immediately following application of bituminous material, spread aggregate uniformly over the surface within the limits of the quantities specified in paragraph QUANITY LIMITS in PART 1. Spreading shall be done with mechanical spreaders. Spread aggregate evenly by hand on all areas missed by the mechanical spreader. Equipment spreading aggregate shall be operated backwards, so that the bituminous material will be covered ahead of the truck wheels. When hand spreading is employed on inaccessible areas, spread aggregate directly from the trucks. Additional aggregate shall be spread by hand over the areas having insufficient cover, and spreading will continue during these operations when necessary.

C. Brooming and Rolling

1. Roll the surface with a pneumatic-tired and a steel-wheeled roller after sufficient aggregate is spread. Continue rolling until no more aggregate can be worked into the treated surface.

The use of the steel-wheeled roller will be discontinued, or a lighter weight steel wheel roller substituted, as directed, if the roller being used causes excessive crushing and shattering of the aggregate. If the aggregate is not distributed properly, broom the surface as soon as possible after the first coverage by the roller, but not until the surface has set sufficiently to prevent excessive marking. Brooming, rolling and supplemental spreading of aggregate shall continue until the surface is cured and rolled sufficiently to key and set the aggregate. In places not accessible to rollers, compact the aggregate with pneumatic tampers. Aggregate that becomes contaminated with foreign matter shall be removed, replaced with clean aggregate, and rerolled, as directed. Maintain and protect the treated areas by use of barricades for a period not to exceed 30 days.

ASPHALT SURFACE TREATMENT 027860 - 8

3.3 APPLICATION OF SECOND COURSE

A. Bituminous Treatment

1. Apply the bituminous material for the second course within 48 hours after construction of the first course, weather permitting. Remove excess aggregate prior to the second application of bituminous material. If the treated surface is excessively moistened by rain, allow the surface to dry for such time as deemed necessary. Perform the second application of bituminous material in the manner specified in paragraph APPLICATION OF FIRST COURSE, including temperature and QUANTITY LIMITS.

B. Aggregate:

1. Immediately following the second application of bitumen, aggregate conforming to the gradation and limits specified in paragraph QUANITTY LIMITS shall be spread uniformly over the bituminous material and processed in the manner specified for the first course.

C. Brooming and Rolling Second Course

1. The surface shall be rolled and broomed in the manner specified for the first course until a thoroughly bonded, smooth, even-textured surface is produced. Sweep off the surface surplus aggregate and remove it prior to final acceptance.

3.4

APPLICATION TEMPERATURE OF MATERIALS

A. Cutback Asphalt

1. Use Saybolt Furol as necessary to provide an application viscosity between 0.00004 and

0.00012 square meters per second 40 and 120 centistokes, kinematic or 20 and 60 seconds.

B. Emulsified Asphalt

Within the following ranges:

RS-1: 21.1-60 degrees C70-140 degrees F

RS-2: CRS-1 and CSR 2: 51.7-85 degrees C125-185 degrees F.

C. Asphalt Cement

1. Use Saybolt Furol as necessary to provide an application viscosity between 0.00004 and

0.00012 square meters per second 40 and 120 centistokes, kinematic or 20 and 60 seconds.

ASPHALT SURFACE TREATMENT 027860 - 9

3.5 TRAVEL APPLICATION

A. Preliminary to providing a complete surface treatment, treat three lengths of at least 100 feet each for the full width of the distributor bar. Use the appropriate typical application rates specified herein for one surface treatment trial. Make other surface treatment trials using various amounts of materials as may be deemed necessary.

3.6 PROTECTION

A. Keep all traffic off surfaces freshly treated with bituminous material. Provide sufficient warning signs and barricades so that traffic will not travel over freshly treated surfaces. Protect the treated areas from traffic for at least 24 hours after final application of bituminous material and aggregate, or for such time as necessary to prevent picking up. Immediately prior to opening to traffic, roll the entire treated area with a self-propelled pneumatic-tired roller.
