CITY OF EVERETT SPECIAL PROVISIONS <br /> <br />Water Main Replacement “Y” – Ph 1 Div 5 – SURFACE TMTS & PVMTS March 2024 <br />Work Order No. UP 3814 SP-167 <br />storage facility having an accessible device, indicating the amount of material in <br />storage, located at the top of the cone or about the third point. Engineer will NOT <br />accept HMA from the storage facility when the HMA in storage is below the top of the <br />cone of the storage facility; except, as the storage facility is being emptied at the end of <br />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 and <br />mixing of the HMA, immediately suspend the use of the RAP until Engineer approves <br />changes necessary to provide adequate RAP breakdown and mixing. After introducing <br />the required amount of mineral materials, RAP, new asphalt binder and asphalt <br />rejuvenator into the mixer, mix the HMA until complete and uniform coating of the <br />particles and thorough distribution of the asphalt binder throughout the mineral <br />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 <br />distribute the mixture. Unless Engineer directs otherwise, provide the nominal <br />compacted layer depth to NOT exceed the following: <br /> <br />HMA Class Course <br />Maximum <br />Compacted Layer <br />Depth (FT) <br />1 inch NA 0.35 <br />3/4 & 1/2 inch Wearing 0.30 <br />3/4 & 1/2 inch Other 0.35 <br />3/8 inch NA 0.15 <br /> <br />On areas where irregularities or unavoidable obstacles make the use of mechanical <br />spreading and finishing equipment impractical, the paving may be done with other <br />equipment or by hand. <br />When more than one JMF is being utilized to produce HMA, place the material <br />produced for each JMF using separate spreading and compacting equipment. Do NOT <br />intermingle HMA produced from more than one JMF. During a work shift place each <br />strip of HMA to a single JMF established for the class of HMA specified, unless there is <br />a need to make an adjustment in the JMF. <br />5-04.3(8) Aggregate Acceptance Prior to Incorporation in HMA <br />For HMA accepted by nonstatistical evaluation the aggregate properties of sand <br />equivalent, uncompacted void content and fracture will be evaluated in accordance <br />with Section 3-04. Sampling and testing of aggregates for HMA accepted by <br />commercial evaluation will be at the Engineer’s option. <br />5-04.3(9) HMA Mixture Acceptance <br />Engineer will use nonstatistical, or commercial evaluation for determining acceptance <br />of HMA. <br />Engineer will use nonstatistical evaluation for the HMA acceptance, unless Contract <br />specifies Commercial Evaluation. <br />Engineer will use Commercial evaluation for Commercial HMA and for other classes of <br />HMA in the following applications: sidewalks, road approaches, paths, trails, temporary
