Fix an armored thermometer to the tank with a temperature range from 40 to 400 degrees F so that the temperature of the bituminous material may be determined at all times.

2.7.9. Power Brooms and Power Blowers

Use power brooms and power blowers suitable for cleaning the surfaces to which the bituminous coat is to be applied.

2.7.10. Vacuum Sweeper

Self-propelled, vacuum pickup capable of completely removing loose material and debris from pavement surface.

2.7.11. Miscellaneous Equipment

Additional equipment shall include, but not be limited to, stiff bristle brooms; squeegees to spread asphalt cement; rollers to smooth fabric; scissors or blades to cut fabric; and brushes for applying cement at fabric overlaps.

2.8. Waybills and Delivery Tickets

Certified copies of waybills and delivery tickets for all materials actually used shall be submitted during the progress of the work.

2.9. Environmental Requirements

Apply hot-mix asphalt coat only when the surface to receive the hot-mix asphalt is dry. A limited amount of moisture (approximately 0.03 gallon/square yard) can be sprayed on the surface of unbound material when prime coat is used to improve coverage and penetration of asphalt material. Apply hot-mix asphalt only when the atmospheric temperature has not been below 45 degrees F for the 12 hours prior to application. Wind conditions shall be suitable for installation: Wind chill may affect the proper application temperatures of materials; materials may be blown about, creating safety dangers; wrappers, coverings, and other debris may become airborne.

2.10. Sequencing

Ensure temporary protection measures are in place to preclude moisture intrusion or damage to installed materials.

2.11. Warranty

Provide material and workmanship warranties meeting specified requirements. Provide a manufacturer’s warranty that has no dollar limit, covers defects in workmanship and material, and has a minimum duration of 1 year.

2.12. Curing Period

Following application of the bituminous material and prior to application of the succeeding layer of asphalt mixture allow the bituminous coat to cure and water or volatiles to evaporate prior to overlaying. Maintain the tacked surface in good condition until the succeeding layer of pavement is placed, by protecting the surface against damage and by repairing and recoating deficient areas. [Allow the prime coat to cure without being disturbed for a period of at least 48 hours or longer, as may be necessary to attain penetration into the treated course. Furnish and spread enough sand to effectively blot up excess bituminous material.]
