The spreader box shall consist of a rectangular frame 10 feet or more in width and not less than 8 feet long, equipped for towing, and with a squeegee screed across the inside of the box about threequarters toward the rear which is adjustable for thickness of application and crown of pavement. The squeegee on the spreader box may be neoprene rubber belting, 1/2 inch thick and 6 to 8 inches in width, held vertically across the width of the box (preferable with 4 inches of "free rubber" for aggregate flexibility) and anchored to an adjustable frame. The front and side of the box shall be lined with 1/4 inch thick belting to prevent slurry leakage and to assure proper spreading. The slurry box shall be equipped with wheels in order that it may be raised off the pavement and quickly towed into position for use on adjacent lanes.(#`  @b.` SprayType Applicator or Distributor: Shall be used for applying the slurry when approved by the Contracting Officer. This equipment shall be equipped with an agitator to keep the slurry uniformly mixed before and during application and so designed to uniformly spread the slurry on the pavement surface at the specified rates of application.(#`  (#  @c.` Other Tools or Equipment: Brushes, hand squeegees, hose equipment, aggregate batched, and sand spreaders, tank trucks, water distributors and flushers, power sweepers, power blowers, barricades, shall be provided as required.(#` 2.03 MIXES: A.@Quantities And Composition of Materials Per Square Yard: The approximate amounts and composition of materials per square yard for the sealcoat shall be as provided in Table 2.

The cracks shall then be cleaned by blowing with compressed air.(#@ B.@Resurfacing: Bituminous pavement surfaces which have been softened by petroleum derivatives or have failed due to any other cause shall be removed to the full depth of the damage and replaced with new bituminous concrete coarser than that of the existing pavement. Areas of the pavement surface to be treated shall be in a firm consolidated condition and sufficiently cured so that there is no concentration of oils on the surface. Areas that have been subjected to fuel or oil spillage shall be wire brushed to remove any accumulations. The accumulations removed by air blowing and the area primed with shellac or a synthetic resin which will not allow the oil in the pavement to bleed through to prevent disbonding of the protective coating. Prior to placing the sealcoat, the surface of the pavement shall be clean and free from dust, dirt, or other loose foreign matter, grease, oil, or any type of objectionable surface film. The existing surface shall be cleaned with a power blower and wire brushes, when approved by the Contracting $ Officer. Where vegetation exists in cracks, the vegetation shall be removed and the cracks cleaned to a depth of two inches. These cracks shall be treated with a concentrated solution of an approved herbicide. (#@ 3.02 APPLICATION: A.@Crack Sealing:(#@  @1.Crack Filling: Cracks shall be sealed immediately following final cleaning of the sides of the cracks. The sides of the cracks shall be surface dry, and the atmospheric and pavement temperatures shall both be above 40 degrees F at the time of installation of crack sealing materials. Open cracks ready for sealing that cannot be sealed under the conditions specified or when rain interrupts filling operations,shall be blown out and allowed to dry prior to installing the crack sealing materials. Crack sealer shall be heated and applied at the temperature specified by the manufacturer. Cracks shall be filled with crack sealer without formation of voids or entrapped air. More than one application of crack sealer may be necessary to fill cracks to the required level. Excess or spilled sealer shall be removed from the pavement and discarded.(#  @2.Weather Limitation:. Crack repair materials shall not be applied in wet cracks or where frost, snow or ice is present nor when the ambient temperature is below 40 degrees F (4 degrees C).(# B.@Resurfacing:(#@  @1.Premixing: When the emulsion and aggregate are blended, the material shall be premixed to produce a slurry seal coat. The quantities of materials to be combined in each batch shall be according to the proportions shown in Table 2.(#  @2.Mixing: Before application, the materials shall be proportioned accurately and mixed by approved mixing equipment. The emulsion and the water are first charged into the mixer and blended to the desired consistency. Aggregate shall be added at a slow and uniform rate while the mixing is continued, mineral aggregate and the latex rubber additive shall then be added. After all the constituents are in the mixer, the mixing shall continue for approximately five minutes longer. The mixing shall produce a smooth, free flowing, homogeneous mixture of uniform consistency. Slow mixing shall be continuous from the time the bitumen is placed into the mixer until the slurry is applied by distributor truck or poured into the spreading equipment. During the entire mixing process, no breaking, segregating, or hardening of the emulsion, nor balling, lumping, or swelling of the aggregate shall be permitted. When transit mixers are used, the drum shall be rotated at its lowest possible speed. The emulsion shall be continuously circulated or agitated from $  the time it has been mixed until its application on the pavement surface. Spray bar nozzles, pumps, or other equipment can be cleaned with coaltar toluene or xylene.(#  @3.Application: After the pavement surface has been inspected, the coating shall be applied over the pavement in three applications according to the method described below. The emulsion shall be thoroughly agitated before use and during use so that a homogeneous consistency is assured for proper and uniform application. The slurry shall be applied at a uniform rate to provide the desired amount. Care shall be taken not to overload the box with slurry but a sufficient quantity shall be maintained to supply a feed against the full width of the squeegee. During the application, surfaces of adjacent structures shall be protected to prevent them from being spattered or marred.(#  @a.` Hand Method: The emulsion shall be applied in two or three coats in the amounts per square yard as stated in Table 2. The material shall be poured in rows on the pavement and spread with a squeegee or brush. This procedure shall be continued until the entire area is covered. The first coat shall be allowed to dry and cure sufficiently to prevent pickup before the second coat is applied.(#`  @b.` Distributor or Applicator: When applied by distributor or approved applicator, the emulsion shall be applied uniformly to the surface of the pavement at the prescribed pressures and in the amounts per square yard as specified in Table 2. The first application shall be cured sufficiently to drive over without damage before the second application is applied. In areas inaccessible to the distributor application may be by the hand method.(#`  @4.Curing: The applied emulsion sealcoat shall be allowed to cure for not less than four hours between coats and not less than fortyeight hours after the 3rd coat, during which time all traffic shall be excluded from the area that has been sealed.(#  @5.Weather Limitations: The tar emulsion seal coat shall not be applied when the weather is foggy or when rain threatens, nor when the atmospheric or pavement temperature is below 50 degrees F, unless otherwise approved by the Contracting Officer. (#  @  3.03 FIELD QUALITY CONTROL: A.@Sampling and Testing: The Government will test all materials and bear such costs; except, the Contractor will bear the costs of retesting when required by initial failure of materials or work to meet specified requirements. The Government will order all tests.
