Furnish a Type 1 Working Drawing of the <br /> manufacturer's product information and recommendations to the Engineer <br /> prior to the start of work, including the manufacturer's recommended heating <br /> time 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 <br /> an excessive amount of material on the pavement surface, stop and correct <br /> the 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: <br /> a.

Also, when a WMA additive is <br /> included in the manufacture of HMA, ensure the discharge temperature of the <br /> HMA does not exceed the maximum recommended by the manufacturer of the <br /> WMA additive. A maximum water content of 2 percent in the mix, at discharge, <br /> will be allowed providing the water causes no problems with handling, stripping, or <br /> flushing. If the water in the HMA causes any of these problems, reduce the <br /> moisture content in 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. <br /> Engineer will NOT accept HMA from the storage facility when the HMA in storage <br /> is below the top of the cone of the storage facility; except, as the storage facility is <br /> being emptied at the end of the working shift. <br /> Water Main Replacement"V" Division 5—SURFACE TREATMENTS April, 2021 <br /> WO No.—UP3730 AND PAVEMENTS <br /> SP-152 <br />
