CITY OF EVERETT SPECIAL PROVISIONS <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 /> HMA Class Course Maximum <br /> ' Compacted Layer <br /> Depth (FT) <br /> 1 inch NA 0.35 <br /> 1 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.
