CITY OF EVERETT SPECIAL PROVISIONS I <br /> to the start of work, including the manufacturer's recommended heating time <br /> and temperatures, allowable storage time and temperatures after initial <br /> heating, allowable reheating criteria, and application temperature range. <br /> Confine hot poured sealant material within the crack. Clean any overflow of <br /> sealant from the pavement surface. If, in the opinion of the Engineer, the <br /> Contractor's method of sealing the cracks with hot poured sealant results in an <br /> excessive amount of material on the pavement surface, stop and correct the <br /> operation to eliminate the excess material. <br /> 5-04.3(4)A2 Crack Sealing Areas Prior to Paving <br /> In areas where HMA will be placed, use sand slurry to fill the cracks. <br /> 5-04.3(4)A3 Crack Sealing Areas Not to be Paved <br /> In areas where HMA will not be placed, fill the cracks as follows: I <br /> a. Cracks 1/4 inch to 1 inch in width -fill with hot poured sealant. <br /> b. Cracks greater than 1 inch in width —fill with sand slurry. <br /> 5-04.3(4)B Vacant <br /> 5-04.3(4)C Vacant <br /> 5-04.3(6) Mixing ' <br /> After the required amount of mineral materials, asphalt binder, recycling agent and <br /> anti-stripping additives have been introduced into the mixer, mix the HMA until <br /> complete and uniform coating of the particles and thorough distribution of the <br /> asphalt binder throughout the mineral materials is ensured. <br /> Ensure the temperature of the HMA when discharged does not exceed the optimum I <br /> mixing temperature by more than 25°F as shown on the reference mix design report <br /> or as approved by the Engineer. Also, when a WMA additive is included in the <br /> manufacture of HMA, ensure the discharge temperature of the HMA does not <br /> exceed the maximum recommended by the manufacturer of the WMA additive. A <br /> maximum water content of 2 percent in the mix, at discharge, will be allowed <br /> providing the water causes no problems with handling, stripping, or flushing. If the <br /> water in the HMA causes any of these problems, reduce the moisture content in <br /> accordance with Engineer's directions. <br /> Storing or holding of the HMA in approved storage facilities for less than 24 hours <br /> will be permitted with Engineer's approval. Engineer will reject HMA held for more <br /> than 24 hours after mixing. Dispose of rejected HMA at no expense to the City. <br /> Provide the storage facility having an accessible device, indicating the amount of <br /> material in storage, located at the top of the cone or about the third point. Engineer <br /> will NOT accept HMA from the storage facility when the HMA in storage is below <br /> the top of the cone of the storage facility; except, as the storage facility is being <br /> emptied at the end of the working shift. <br /> Size recycled asphalt pavement (RAP) utilized in the production of HMA prior to <br /> entering the mixer to produce a uniform and thoroughly mixed HMA. If there is <br /> evidence of the recycled asphalt pavement not breaking down during the heating <br /> and mixing of the HMA, immediately suspend the use of the RAP until Engineer <br /> approves changes necessary to provide adequate RAP breakdown and mixing. <br /> After introducing the required amount of mineral materials, RAP, new asphalt binder I <br /> and asphalt rejuvenator into the mixer, mix the HMA until complete and uniform <br /> coating of the particles and thorough distribution of the asphalt binder throughout <br /> the mineral materials, and RAP is ensured.
