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-163 <br />Provide for the setup and operation of the field testing facilities of the City as <br />provided for in Section 3-01.2(2). <br />5. Sampling HMA – Provide for sampling HMA by one of the following methods: <br />a. A mechanical sampling device attached to the HMA plant. <br />b. Platforms or devices to enable sampling from the hauling vehicle without <br />entering the hauling vehicle. <br />5-04.3(3)B Hauling Equipment <br />Provide trucks used for hauling HMA having tight, clean, smooth metal beds and a <br />cover of canvas or other suitable material of sufficient size to protect the mixture <br />from adverse weather. Securely attach cover whenever the weather conditions <br />during the work shift include, or are forecast to include precipitation or an air <br />temperature less than 45°F or when time from loading to unloading exceeds 30 <br />minutes to protect the HMA. <br />Provide an environmentally benign means to prevent the HMA mixture from <br />adhering to the hauling equipment. Drain excess release agent prior to filling <br />hauling equipment with HMA. Do NOT use petroleum derivatives or other coating <br />material that contaminate or alter the characteristics of the HMA. For live bed <br />trucks, the conveyer shall be in operation during the process of applying the <br />release agent. <br />5-04.3(3)C Pavers <br />Provide HMA pavers that are self-contained, power-propelled units, with <br />an internally heated vibratory screed and shall be capable of spreading and <br />finishing courses of HMA plant mix material in lane widths required by the paving <br />section shown in the Plans. <br />Provide HMA paver in good condition and have the most current equipment <br />available from the manufacturer for the prevention of segregation of the HMA <br />mixture installed in good condition and in working order. Provide equipment <br />certification listing the make, model, and year of the paver and note retrofitting of <br />any equipment. <br />Operate the screed in accordance with the manufacturer’s recommendations and <br />so it effectively produces a finished surface of the required evenness and texture <br />without tearing, shoving, segregating, or gouging the mixture. Provide a copy of <br />the manufacturer’s recommendations upon City’s request. Extensions producing <br />the same results, including ride, density, and surface texture as obtained by the <br />primary screed will be allowed. Do NOT use extensions without augers and an <br />internally heated vibratory screed in the Traveled Way. <br />When specified in the Contract, reference lines for vertical control will be required. <br />Place lines on both outer edges of the Traveled Way of each Roadway. Horizontal <br />control utilizing the reference line will be permitted. Control the grade and slope <br />for intermediate lanes automatically from reference lines or by means of a mat <br />referencing device and a slope control device. When the finish of the grade <br />prepared for paving is superior to the established tolerances and when, in the <br />opinion of the Engineer, further improvement to the line, grade, cross-section, and <br />smoothness can best be achieved without the use of the reference line, a mat <br />referencing device may be substituted for the reference line. Substitution of the <br />device will be subject to the continued approval of the Engineer. A joint matcher <br />may be used subject to the approval of the Engineer. The reference line may be <br />removed after the completion of the first course of HMA when approved by the <br />Engineer. Whenever the Engineer determines that any of these methods are <br />failing to provide the necessary vertical control, the reference lines will be <br />reinstalled by the Contractor.
