PART 3 EXECUTION

3.01 PREPARATION FOR SEAL COAT

A. Immediately before applying the asphaltic emulsion, the surface to be sealed shall be clean and dry. Cleaning shall be performed by sweeping, flushing or other means necessary to remove all loose articles of paving, all dirt and all other extraneous material.

32 01 13 - 4

B. When seal coats are to be applied to an untreated material, a prime coat consisting of liquid asphalt shall be applied to the material in place at a rate of from 0.35-gallon per square yard.

3.02 APPLYING ASPHALT

A. Unless otherwise specified, heat and apply asphalt in conformance with the provisions in Section 93, "Liquid Asphalts" of CALTRANS Standard Specifications, 2006. The application rates of shall be 0.35 gallons per square yard for the first application and 0.25 gallons per square yard for the second application.

B. Asphalt shall not be applied when weather conditions are unsuitable. Seal coats requiring screenings shall not be applied until sufficient screenings are on hand to immediately cover the asphaltic emulsion, or when the atmospheric temperature is below 65 degrees Fahrenheit or above 110 degrees Fahrenheit, or when the pavement temperature is below 80 degrees Fahrenheit. Fog seal coat shall not be applied when the atmospheric temperature is below 40 degrees Fahrenheit.

C. The COR will notify the Contractor, no later than 4:00 PM, if it is anticipated that the next working day will not be suitable for the application of seal coat. This notice may be given on the day preceding the date the Contractor intends to begin work, any working day after the Contractor has begun work, and any day previously named by the COR as a day unsuitable for applying seal coat. When the COR has declared a day to be unsuitable by reason of expected low temperature or unsuitable weather conditions, the Contractor shall not apply any new seal coat. If maintenance of previously applied seal coat can be performed, the Contractor shall continue to perform the maintenance. These unsuitable days will not be counted as working days regardless of the actual weather conditions and the fact that seal coat maintenance work is performed by the Contractor.

D. If the Contractor has not been notified by the COR of an anticipated unsuitable day and at the beginning of the work day the weather is unsuitable for the application of seal coats, but maintenance of previously applied seal coat can be performed, the Contractor shall not apply any seal coat. Binder and screenings brought to the project shall be returned, stored or disposed of as directed by the COR. The Contractor shall continue maintenance of previously applied seal coat. Applying asphalt shall be discontinued sufficiently early in the day to permit the termination of traffic control prior to darkness. Asphalt shall be applied to the pre-approved areas.

E. Asphalt shall not be applied a greater distance than can be immediately covered by screenings, unless otherwise permitted by the COR.

F. The cut off of asphalt shall be made on building paper or similar material spread over the surface. Paper shall also be placed over the treated surface for a sufficient length at the beginning of a spread to avoid spraying existing pavement or previously placed screenings and so that the nozzles are spreading properly when the uncovered surface is

32 01 13 - 5 reached. The building paper shall then be removed and disposed of in a manner satisfactory to the COR.

G. The distribution of asphalt shall not vary more than 15 percent transversely from the average as determined by tests, nor more than 10 percent longitudinally from the specified rate of application as determined by CALTRANS’s California Test 339.

3.03 SPREADING SCREENINGS

A. Screenings for seal coats shall be spread immediately following the application of the asphaltic emulsion. The spread rate of screenings for the various types of seal coats shall be:

1. First Application spread rate of 26 pounds/square yard.

2. Second application spread rate of 16 pounds/square yard.

B. Screenings shall be spread by means of a self-propelled chip spreader, equipped with a mechanical device which will spread the screenings at a uniform rate over the full width of a traffic lane in one application. The joint between adjacent applications of screenings shall coincide with the line between designated traffic lanes.

C. Operating the chip spreader at speeds which cause the chips to roll over after striking the bituminous covered surface will not be permitted.

D. The transverse cut off of screenings shall be complete and any excess screenings shall be removed from the surface prior to resuming operations.

E. Stockpiling of screenings prior to placing will be permitted; however, any contamination resulting during storage or from reloading operations will be cause for rejection.

F. Screenings shall be surface damp at the time of application, but excess water on the aggregate surface will not be permitted. Screenings shall be redampened in the vehicles prior to delivery to the spreader when directed by the COR.

G. Asphalt shall be covered with screenings before setting or “breaking” of the asphalt occurs.

3.04 FINISHING

A. After the screenings have been spread upon the asphaltic emulsion, piles, ridges or uneven distribution shall be carefully removed to ensure against permanent ridges, bumps or depressions in the completed surface. Additional screenings shall be spread in whatever quantities may be required to prevent picking up by the rollers or traffic, after which the surface shall be rolled.

32 01 13 - 6

B. Rollers shall be pneumatic-tired type. A minimum of 2 pneumatic-tired rollers conforming to the provisions in Section 39-5.02, Compacting Equipment, shall be furnished.

C. Initial rolling shall consist of one complete coverage and shall begin immediately behind the spreader. Asphalt and screenings shall not be spread more than 2,500 feet ahead of completion of initial rolling operations. Secondary rolling shall begin immediately after completion of the initial rolling. The amount of secondary rolling shall be sufficient to adequately seat the screenings and in no case shall be less than 2 complete coverages.

D. Unless otherwise provided in the special provisions or directed by the COR, seal coat surfaces shall be maintained, including the traffic control required for maintenance operations, for a period of 4 consecutive calendar days beginning on the day screenings are applied to the asphaltic emulsion. Maintenance of the surface shall include brooming and the distribution of screenings over the surface to absorb any free bituminous material, to cover any area deficient in cover coat material and to prevent formation of corrugations. Clean sand may be used in lieu of screenings to cover any excess of asphalt which comes to the surface. The use of roadside material for this purpose will not be permitted.

E. Brooms for finishing and maintaining seal coat screenings shall be the self-propelled type. When brooming is required adjacent to curbs, gutters, dikes, berms, railings or other barriers which would prevent loose screenings from being swept completely off the roadway, the self-propelled brooms shall also be capable of removing the loose screenings from the surface during brooming. In addition to the self-propelled brooms required for maintaining previously placed screenings, at each location where screenings are to be spread, a minimum of 3 self-propelled brooms shall be available, prior to the start of spreading the screenings at a location.

F. The surface of the seal coat shall be broomed as often as necessary during the 4 calendar day maintenance period to maintain the surface free of loose screenings. At the end of the 4 consecutive calendar day maintenance period, any excess screenings shall be removed from paved areas. Brooming of seal coat surfaces shall be performed in such a manner that the screenings set in the asphalt will not be displaced. The exact time of brooming will be determined by the COR. As a minimum, brooming will be required at the following approximate times:

1. Immediately prior to opening any lane to public traffic, not controlled with pilot cars.

2. As a first order of work on the morning following application of screenings, on any lane that has been open to public traffic, not controlled with pilot cars.

3. At the end of the 4 calendar day maintenance period.

G. Excess screenings remaining on the surface after the first application of a "double" seal coat shall be removed prior to the second application of asphaltic emulsion.

32 01 13 - 7

H. When directed by the COR, excess screenings shall be salvaged and stockpiled at designated locations.

I. Excess screenings which in the opinion of the COR are not salvable and which interfere with drainage shall be removed and disposed of by the Contractor at the Contractor's expense. The removed screenings shall be disposed of in conformance with the provisions in Section 7-1.13, Disposal of Material Outside the Highway Right of Way, or along embankment slopes, or at other suitable locations if permitted by the COR.

J. The completed surface shall present a uniform appearance and shall be free from ruts, humps, depressions or irregularities due to an uneven distribution of asphalt or screenings.

3.05 MAINTENANCE

A. Maintain paved areas until acceptance of work by Government.
