CITY OF EVERETT SPECIAL PROVISIONS <br /> <br />Water Main Replacement “Y” – Ph 2 Div 5 – SURF TREATMTS & PVMTS October 2025 <br />Work Order No. UP 3814 SP-166 <br />Category 2: Sensitive information <br />Category 2: For official use only / disclosure permissible by law. <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: <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 anti- <br />stripping additives have been introduced into the mixer, mix the HMA until complete and <br />uniform coating of the particles and thorough distribution of the asphalt binder throughout <br />the mineral materials is ensured. <br />Ensure the temperature of the HMA when discharged does not exceed the optimum <br />mixing temperature by more than 25°F as shown on the reference mix design report or <br />as approved by the Engineer. Also, when a WMA additive is included in the manufacture <br />of HMA, ensure the discharge temperature of the HMA does not exceed the maximum <br />recommended by the manufacturer of the WMA additive. A maximum water content of 2 <br />percent in the mix, at discharge, will be allowed providing the water causes no problems <br />with handling, stripping, or flushing. If the water in the HMA causes any of these <br />problems, reduce the moisture content in accordance with Engineer’s directions. <br />Storing or holding of the HMA in approved storage facilities for less than 24 hours will be <br />permitted with Engineer’s approval. Engineer will reject HMA held for more than 24 hours <br />after mixing. Dispose of rejected HMA at no expense to the City. Provide the storage <br />facility having an accessible device, indicating the amount of material in storage, located <br />at the top of the cone or about the third point. Engineer will NOT accept HMA from the <br />storage facility when the HMA in storage is below the top of the cone of the storage <br />facility; except, as the storage facility is being emptied at the end of the working shift. <br />Size recycled asphalt pavement (RAP) utilized in the production of HMA prior to entering <br />the mixer to produce a uniform and thoroughly mixed HMA. If there is evidence of the <br />recycled asphalt pavement not breaking down during the heating and mixing of the HMA, <br />immediately suspend the use of the RAP until Engineer approves changes necessary to <br />provide adequate RAP breakdown and mixing. After introducing the required amount of <br />mineral materials, RAP, new asphalt binder and asphalt rejuvenator into the mixer, mix <br />the HMA until complete and uniform coating of the particles and thorough distribution of <br />the asphalt binder throughout the mineral materials, and RAP is ensured. <br />5-04.3(7) Spreading and Finishing <br />Lay the mixture upon an approved surface, spread, and strike off to the established <br />grade and elevation. Provide HMA pavers complying with Section 5-04.3(3) to distribute <br />the mixture. Unless Engineer directs otherwise, provide the nominal compacted layer <br />depth to NOT exceed the following:
