4. MONITORING OF TRAFFIC: The contractor shall work with the park to best utilize area during joint cleaning and sealing operations. Signs and or flagging may be utilized for flow of tour route traffic.

5. RIGHT-OF-WAY: All work under this contract shall be done within the confines of Hamburg-Purdy road. Upon completion, the contractor shall leave the area free from surplus sealant or debris from the cleaning and sealing process. It shall be the responsibility of the contractor to restore any items (i.e. curbs, sidewalks, driveways, shrubbery, utility facilities, etc.) within the area damaged due to the sealing process.

6. TRAFFIC CONTROL: The work shall be carried out at all times in a manner causing a minimum interference with visitor traffic. The contractor shall provide necessary barricades and warning signs. The contractor shall barricade or divert traffic from all cleaning and sealing until it is cooled for a sufficient period of time to prevent scuffing or flushing of the joints wherever possible. The contractor shall post signs (in areas determined ), at least 24 hours prior to commencement of cleaning and sealing operations. It shall be the contractors responsibility to coordinate with the park to ensure all vehicles are prevented from entering the work site.

7. UTILITIES TO BE MARKED: The contractor shall work with park staff to mark and record each utility opening or manhole which is affected if any. Any utility facility which is broken or damaged by the contractor shall be replaced entirely at the contractors cost.

8. JOINT CLEANING AND SEALING APPLICATION: This work consists of routing, cleaning, sealing, and filling cracks in concrete asphalt pavement surfaces. Clean expansion joints to a depth of 2 inches. Clean longitudinal and transverse joints to a depth of 1.5 inches. Fill designated joints with poured joint filler. Reseal joints immediately after cleaning. Place sealant below concrete surface to preclude the tracking of sealant onto concrete roadway surfaces.

9. WEATHER LIMITATIONS: Bituminous mixtures shall not be placed (1) when either the air temperature or the temperature of the surface on which the mixture is to be placed is below 40 degrees F. (2) on any wet or frozen surface or (3) when weather conditions prevent the proper handling or finishing of the mixture, as determined by the park or his/her designated representative. Mixture shall not be placed during inclement weather.

10. EQUIPMENT REQUIREMENTS: Equipment; Furnish equipment with the following capabilities:

· Router – A power rotary impact router or vertical spindle router capable of creating a reservoir to the required depth and width without damaging adjacent pavement.

· Air Lance - A hot compressed air lance capable of providing clean, oil-free compressed air at a volume of 100 cubic feet (2.8 cubic meters) per minute, a pressure of 120 pounds per square inch (830 kilopascals), and a temperature of 2000 °F (1100 °C).

· Application Wand - A wand attached to a heated hose attached to a heated material chamber that maintains material temperature within manufacturer’s tolerances. Supply proper wand tips for desired application.

· Heating Kettle - An indirect-heating double boiler capable of constant and effective agitation. Fill the space between the inner and outer shells with oil or other heat transfer medium. Provide an accurate and calibrated thermometer with a range from 200 to 600 °F in 5 °F graduations (90 to 320 °C in 2 °C graduations) located so the material temperature can be safely checked.

· Squeegee or Screed - A hand-held squeegee or screed of appropriate configuration for filling cracks flush with the surface, underfilling cracks to recess below the surface, or overfilling cracks to an overband shape.

· Compressor - A compressor capable of producing oil- and water-free air at a minimum rate of 100 cubic feet (2.8 cubic meters) per minute with a minimum continuous line pressure of 125 pounds per square inch (860 kilopascals).

11. CLEANING AND SEALING SPECIFICATION:

· Cleaning: Prevent debris from entering waterways, travel lanes open to public traffic, or areas designated not to be disturbed. Remove dirt, dust, and other deleterious material from the crack walls and cavity using a stream of air or other approved methods. Blow or brush dry material off the pavement surface.

· Sealing and Filling: Dry the crack surfaces with the hot air lance before sealing or filling. Do not seal or fill cracks when the pavement surface temperature is below 40 °F (5 °C) and weather conditions are rainy or foggy.

· Sealing: Submit a copy of and adhere to the manufacturer’s recommendations for heating and applying the hot applied crack material. Heat the material to pouring temperature in a heating kettle and continuously agitate the material.

· Discard Sealant When:

· Heated above the safe heating temperature recommended by manufacturer.

· Held at pouring temperature for more than 12 hours.

· Reheated more than once.

· Not consistent or uniform in appearance.

12. PROCESS OF SEALING AND PREP:

· Warm and dry the crack surfaces using a hot-compressed air lance if the pavement temperature is lower than 40 °F (5 °C) or moisture is present. Keep the lance moving to prevent burning the pavement surface. Place and finish the material within 5 minutes after heating the pavement surface with the lance.

· Use an application wand to place material in each crack or joint from the bottom up. Insulate the wand to maintain pouring temperature while placing material. Return the wand to the heating kettle immediately after sealing each crack. Use a squeegee or screed to strike off the material.
