CITY OF EVERETT SPECIAL PROVISIONS <br /> <br />Beverly Lake Water Quality Retrofit Division 5 – SURFACE TREATMENTS August 2023 <br /> <br />AND PAVEMENTS <br />WO No. – UP3745 SP - 167 <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 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 />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 <br />NOT intermingle HMA produced from more than one JMF. During a work shift place <br />each strip of HMA to a single JMF established for the class of HMA specified, unless <br />there is 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 <br />acceptance 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 <br />of HMA in the following applications: sidewalks, road approaches, paths, trails, <br />temporary pavement, and pavement repair. Engineer will need to approve other <br />nonstructural applications of HMA accepted by commercial evaluation. Sampling <br />and testing of HMA accepted by commercial evaluation will be at the Engineer’s <br />option. <br />The mix design will be the initial JMF for the class of HMA. The Contractor may <br />request a change in the JMF. Any adjustments to the JMF will require the Engineer’s <br />approval and may be made in accordance with this section. <br />5-04.3(9)A HMA Tolerances and Adjustments <br />1. Job Mix Formula Tolerances – Provide mixture at the time of <br />acceptance within the following tolerances: <br />For Asphalt Binder and Air Voids (Va), the acceptance limits are determined by <br />adding the tolerances below to the approved JMF values. These values will
