193 407.9 -PROTECTION OF THE PAVEMENT AND TRAFFIC CONTROL : The Contractor shall be responsible for the protection of the surface against damage by their equipment and personnel. Traffic shall not be permitted on any part of the work under construction until the treatment has cured sufficiently to prevent raveling or picking up under traffic. The applicable provisions of 636 shall apply for regulating traffic.
407.10 Quantities of Materials :
The application rates referenced in Table 407.10 shall be used as guide to assure the proper amount of asphalt is distributed over the pavement surface under various pavement conditions. The undiluted application rate refers to the unmodified emulsion tha t meets all standard specifications of the specified grade. When an SS or CSS grade emulsion is diluted with water at the allowable 1:1 ratio, the residual asphalt content is defined as the amount of asphalt remaining on the pavement surface after all wat er has evaporated from the emulsion. Unless otherwise specified on the Plans, the recommended application rates for undiluted and diluted asphalt fog seal shall be as specified in Table 407.10. These rates are provided for guidance and may be adjusted as directed by the Engineer based on field conditions. TABLE 407.10 Surface to be Sealed Application Rate (gal/sy) (Note 1) Undiluted Diluted (1:1) Oxidized HMA 0.06 – 0.08 0.12 – 0.15 Chip Seals See Specification 405 Note 1: Application rates are for slow setting emulsions grades (SS and CSS) that contain approximately 60% asphalt material. Non -Tracking Emulsions may contain different asphalt contents. Refer to manufacturer’s recommendations for application rates.
407.11 Method of Measurement :
No materials shall be removed from the Project for any purpose until the operation has been completed and the quantities of materials incorporated into the operations have been determined, except when authorized by the Engineer. The quantity of “Asphalt Material” for fog seal shall be the number of gallons, prior to dilution, incorporated into the completed work. Any applicable dilution rates, shall be supplied to the Engineer by the Contractor on the material delivery ticket. Dry sand or stone chips used as a blotter course due to excessive use of fog seal shall be considered incidental to the work.
407.12 Basis of Payment :
The quantiti es, determined as provided above, will be paid for at the contract unit prices bid for the items listed below, which prices and payments shall be full compensation for furnishing all the materials and doing all the work prescribed in a workmanlike and acce ptable manner, included all labor, tools, equipment, supplies, and incidentals necessary to complete the work.
