3.2.3 Application of Bituminous Material

Following the preparation and inspection of the pavement surface, apply the seal coat material at the specified application rates. Uniformly apply the bituminous material in a single pass of the distributor and with either a double or triple lap spray over the surface to be sealed. Apply bitumen to a dry surface with a minimum pavement temperature of 70 degrees Fahrenheit. Spread building paper on the surface for a sufficient distance back from the ends of each application so that flow through the spray bar may be started and stopped on the paper and so that all sprays will be operating at the proper pressure on the surface to be sealed. Immediately after the bituminous material application, remove the building paper.

Apply bituminous material to all areas missed with the distributor. No smoking, fires, or flames, other than the heaters that are a part of the equipment, will be permitted within 25 feet of heating, distributing, and transferring operations of bituminous material other than bituminous emulsions.

3.2.4 Aggregate Application Rate

Spread the aggregate in the quantities shown in TABLE III. The exact quantities within the range specified, which may be varied to suit field conditions, will be determined by the Contractor, and approved by the Contracting Officer prior to use. The aggregate weights shown in this table are those of aggregate having a specific gravity of 2.65. If the specific gravity of the aggregate to be used is less than 2.55 or greater than 2.75, make adjustments in the number of pounds of aggregate required per square yard to insure a constant volume of aggregate per square yard of treatment.

3.2.5 Application of Aggregate

Spread the specified quantity of cover aggregate uniformly over the bituminous material. Provide sufficient aggregate on trucks at the work site to cover the distributor load of bituminous material before the bituminous material is applied. No bituminous material may be down more than 3 to 4 minutes before it is covered with aggregate. Uniformly spread aggregate with aggregate-spreading equipment. Lightly recover areas having insufficient cover with additional aggregate by hand during the operations whenever necessary.

3.2.6 Rolling and Brooming

Begin rolling operations immediately following the application of cover aggregate. Perform rolling using pneumatic-tired rollers. Operate the rollers at a speed that will not displace the aggregate. Continue rolling until the aggregate is uniformly distributed and keyed into the bituminous material. Sweep off the surface and remove all surplus aggregate not less than 24 hours nor more than 4 days after rolling is completed. Immediately prior to opening to traffic, roll the entire treated area with a self-propelled pneumatic-tired roller.

3.3.1.3 Stripping

Perform stripping test on aggregate from each source, in accordance with ASTM D3625/D3625M, prior to incorporation into the work and when the source is changed.

3.3.2 Bituminous Material Sample

Obtain a sample of the bituminous material used under the supervision of the Contracting Officer. The sample will be retained by the Government.

3.4 TRIAL APPLICATION - SEAL COAT

Prior to applying the seal coat, place a test section at least 100 feet long by 20 feet wide using the approved job materials and roll them in accordance with the specified requirements. Perform tests to determine the application rates of the bitumen and aggregate. If the tests indicate that the seal coat test section does not conform to the specification requirements, make necessary adjustments to the application equipment and to the spreading and rolling procedures, and construct additional test sections for conformance to the specifications. Where test sections do not conform to specification requirements, remove seal coat at no expense to the Government; no separate payment will be made for seal coat materials and labor, either in placement or removal of any test section. Perform quality control sampling and testing during construction as required in paragraph FIELD QUALITY CONTROL above.

3.5 FOG SEAL APPLICATION

3.5.1 Sample Application

Determine the required application rate from a sample installation. Select an area of the prepared pavement at least 300 feet long and as wide as the distributor spray bar. Dilute emulsified asphalt with an equal part of water or as agreed to by the Contracting Officer. Apply the water diluted asphalt emulsion in at least three test sections; each a minimum of 100 feet long. Make trial applications at residual rates of 0.058, 0.14, and

0.20 gallons/square yard. The trial application rates may be modified if approved by the Contracting Officer. Additional trial applications may be made if warranted by pavement surface conditions. Use the rate which has been satisfactorily applied without leaving an excess of asphalt residue on the surface and has been approved, for the fog seal.

3.5.2 Application Inspection

Inspect application of fog seal for uniformity. During application, take one sample for each 500 square yards of surface area to receive emulsified asphalt. Weigh samples to determine conformance with application rate.

3.5.3 Inspection Reports

Furnish a written report citing climatic temperature during application of fog seal, emulsion temperature during application, rate of emulsion application, and any significant observations.

3.5.4 Application

Following preparation of the surface, apply the water diluted asphalt emulsion at the rate determined from the trial application. Maintain application temperature of emulsified asphalt between 75 and 160 degrees F.

To obtain uniform application of the fog seal at the junction of previous and subsequent applications, spread building paper on the surface of the applied material for a sufficient distance back from the ends of each application so that flow from the spray bar may be started and stopped on the paper, and so that all sprayers will operate at full force.

Immediately after application, remove and properly dispose of the building paper. Treat spots unavoidably missed with the hand spray equipment. Base bids on application of diluted emulsion at 0.0514 gsy. If the actual amount required is more or less than 0.14 gsy, an adjustment in the contract price will be made as provided by the contract.

3.6 SITE PROTECTION

During applications, protect adjacent buildings, structures, vehicles, manhole covers, inlet grates, and trees to prevent being spattered or marred.

3.7 TRAFFIC CONTROL

Protect freshly placed coatings from damage by traffic. Provide sufficient warning signs and barricades to prevent traffic over freshly treated surfaces. Protect treated areas from traffic for at least 24 hours after final application of coatings, or for such time as necessary to prevent picking up. Provide warning signs and barricades for proper traffic control, in accordance with MUTCD.

Provide steel cable anchor brackets conforming to ASTM A709/A709M Grade 36 or ASTM A36/A36M. Provide anchor posts and anchor post plates conforming to ASTM A36/A36M. Galvanize cable anchor brackets, anchor posts, and anchor post plates after fabrication in accordance with ASTM A123/A123M.

Provide steel [rods] [hook or J bolts] conforming to ASTM A449 or ASTM A568/A568M and galvanize the top 6 inches in accordance with ASTM A123/A123M. Provide hex nuts conforming to ASTM A563.

2.2.6 Concrete

ASTM C94/C94M, using 3/4 inch maximum aggregate, and having minimum compressive strength of 4000 psi at 28 days. Reinforcing steel must be deformed bars conforming to ASTM A615/A615M, ASTM A706/A706M, or ASTM A1035/A1035M grade 40.

3.1 POSTS

Posts may be placed by driving or by setting in excavated holes. Post holes for guardrail posts must be round and at least 4 inches larger, in diameter, than the greater dimensions (not the diagonal) of the posts, and must be backfilled around the posts with material removed or other suitable soil, placed in lifts not exceeding 4 inches, each lift thoroughly tamped.

When placed by driving, drive the posts plumb, to the depth and in the position indicated. Remove posts which are broomed, split or damaged in any other way and replace with a sound post. Carry on driving operations in such manner that nearby structures, shoulders, or pavements are not damaged. Cuts and abrasions in preservative-treated posts and blocks must have the newly exposed surfaces treated with at least three applications of the same type of preservative with which the material was originally treated. Each application must be reasonably dry before the succeeding coat is applied. At the time a timber post is installed, any seasoning check which extends the full length of the piece cannot exceed 1/4 inch in width. Adjust posts used for vertical transition in length so that a minimum of 60 inches will be buried. Where guardrail cross buried structures and 60 inches of bury is not obtainable, install the guardrail post as deep as possible and with a 24 inch diameter concrete encasement for the full depth of bury.

3.2 THREE CABLE GUARDRAIL

3.2.1 Posts

Set all posts plumb and firm and spaced as indicated.

3.2.2 Cable Splices, Compensating Devices and Turnbuckle Cable End Assemblies

Stagger cable splices. Provide a minimum of 20 feet between any pair.

Provide a minimum of 100 feet between cable splices on the same cable. For length of cable runs up to 1000 feet, use a compensating device on one end and a turnbuckle on the other end of each individual cable. For length of cable runs from 1000 feet to 2000 feet, use a compensating device on the ends of each individual cable. For length of cable runs over 2000 feet, start a new stretch by interlacing at the last parallel post.

3.2.3 Pretension of Cable

Install and tension the cable barrier as follows:

a. Properly seat the spring in the compensator device and permanently mark the unloaded spring position on the compensator rod.

b. Install spring end assemblies at one end of the barrier and secure to the anchor.

c. With cable strung through the hook bolts, introduce tension into the cable at the opposite end of the barrier to compress the installed springs approximately 3.5 inches.

d. Clamp this tension in the cable while the end assemblies are installed at the second anchor.

e. Remove the slack between the clamp point and the second anchor by taking up the turnbuckle. If springs are also used at this end, compress them approximately 3.5 inches.

f. After two weeks at this setting, reset the spring compression as indicated based on the temperature at the time of adjustment.
