4. MAINTENANCE REQUIREMENTS

3. Cleaning of cracks: The cracks shall be steel wire brushed, broomed, cleaned using compressed air or pressurized water jet, or cleaned and dried using a hot lance (use of a back-pack hot air blower will not be sufficient), as shown in the Schedule of Items, in order to remove all loose material, vegetation, and other objectionable material.

The cracks shall be sealed from the bottom up. The filler material shall be placed within 1/8-inch of the top of the crack. Any excess material shall be leveled flush to the surface with a "V" shaped squeegee device. The excess material will be squeegeed so as not to exceed 1 1/2- inches on each side of the crack. Excess material remaining in the squeegee at the end of the crack will be distributed over the crack in a return motion. If settlement of the filler material occurs, the cracks shall be refilled until they are again within 1/8-inch of the finished surface. No excess build-up of filler material will be permitted. Any spillage or loose material shall be removed from the surface.

5. Weather Limitations: The filler material shall not be applied when it is raining, excessive moisture is present, or either atmospheric or pavement temperature is 45 degrees Fahrenheit and falling. Filler material may be applied when moisture is not present and either the atmospheric or pavement temperature is 40 degrees Fahrenheit and rising.

5. MEASUREMENT

The quantity will be measured by the linear foot, lump sum, or pound of filler material used as shown in the Schedule of Items. When measurement by the pound is specified, the Government may require the weighing of equipment for determination of actual quantities of material used. Payment by the pound will not include any materials wasted or not used as specified.

1. Payment shall be made at the contract unit price for cracks repaired as specified. This payment shall be full compensation for all labor, equipment, materials, traffic control, tools and incidentals necessary to complete the work.
