PART 3 - EXECUTION

3.1 PREPARATION OF SURFACE: Prior to application of the slurry seal, the existing pavement surface shall be cleaned and accumulation of water removed.

3.1.1 All dust, dirt, oil, grease, fuel, loose or flaky traffic paint, and other objectionable material shall be removed from the pavement surface.

3.1.2 The Contracting Officer may direct the Contractor to repair cracks and selected unsatisfactory areas according to Section 32 12 11.25:

REPAIR OF BITUMINOUS PAVEMENTS.

3.1.3 All vegetation shall be removed, and these areas treated with a herbicide. The type of herbicide and method of application shall be approved by the Contracting Officer.

3.1.4 Immediately prior to application of the sealer mixture, the surface of the pavement and all crack faces shall be moistened with a fog spray of water from the spray bar on the sealer machine. No free water shall be on the surface of the pavement following the fog spray. The rate of application of the fog spray shall be adjusted during the day to suit pavement temperature, surface texture, humidity, and dryness of the pavement

3.2 PREPARATION AND APPLICATION OF SEALER:

3.2.1 The sealer mixture shall be prepared in a suitable mixing plant, subject to approval by the Contracting Officer.

3.2.2 The sealer shall be mixed in a suitable plant as described in

32 01 13.35-5 paragraph EQUIPMENT. The sealer mixture shall be of the desired consistency with no segregation when deposited on the surface of the pavement. No additional elements shall be added. The sealer mixture shall show no signs of uncoated aggregate, or segregation, or premature breaking of emulsion when applied to the pavement surface.

3.2.3 Where small amounts of sealer are required, making mechanical mixing uneconomical, mixing may be accomplished by hand. The preparation requirements are the same as given in the preceding paragraph for mechanical mixing.

3.2.4 Two coats shall be applied with sand at an application rate of

0.20 gallons per square yard. Each application shall be thoroughly cured before another application is placed. No oversized aggregate particles shall be allowed in the sealer mixture. Streaks shall not be left in the finished

3.2.5 Longitudinal joint between adjacent lanes shall have no visible overlaps, pinholes, or uncovered areas. Thick spots caused by overlapping shall be smoothed immediately with hand squeegees before the sealer mixture cures. Overlaps which occur at transverse joints shall also be smoothed before the sealer mixture cures, so that a uniform surface is obtained which contains no breaks or discontinuities. Joints should be made while the first coat is still workable.

3.2.6 Sealer mixture shall possess sufficient stability so that segregation or premature breaking of emulsion does not occur. The mixture shall be homogeneous following mixing and spreading, free of water or emulsion bleeding.

3.2.7 Areas which cannot be reached with the distributor or areas with minor defects shall have the sealers applied by hand with hand squeegees.

3.3 CURING: Sealed pavement shall be protected from traffic by barricades and markers until the seal has cured a minimum of 24 hours. Areas which are damaged by traffic or from other causes shall be repaired by the Contractor at no additional cost to the Government.

3.4 CLEANUP: On completion of work, all trash, discarded seal material, or other refuse shall be collected and removed from the site and disposed of in accordance with Section 01010: Scope of Work.

3.5 TEST SECTION: Prior to applying the slurry seal, a test section 100 feet long and 20 feet wide shall be placed by the Contractor using the approved mix and equipment in accordance with the specified requirements.

The test section will be evaluated for pavement preparation, workability, stability, curing time, application rate, consistency of thickness, surface finish, joint quality, segregation, premature breaking, and bleeding. The test section may be left in place as part of the finished work if it meets the requirements of the specifications. If not, it shall be removed by the Contractor at no additional cost to the Government.
