CITY OF EVERETT SPECIAL PROVISIONS I <br /> 1. Equipment for Preparation of Asphalt Binder — Equip tanks for the <br /> storage of asphalt binder to heat and hold the material at the required <br /> temperatures. Accomplish the heating by steam coils, electricity, or other <br /> approved means so that no flame is in contact with the storage tank. Provide <br /> the circulating system for the asphalt binder designed to ensure proper and <br /> continuous circulation during the operating period. Provide a valve for the <br /> purpose of sampling the asphalt binder placed in either the storage tank or <br /> in the supply line to the mixer. <br /> 2. Thermometric Equipment— Provide an armored thermometer, capable of <br /> detecting temperature ranges expected in the HMA mix, fixed in the asphalt <br /> binder feed line at a location near the charging valve at the mixer unit and <br /> location convenient and safe for access by Inspectors. Provide plant <br /> equipped with an approved dial-scale thermometer, a mercury actuated <br /> thermometer, an electric pyrometer, or another approved thermometric <br /> instrument placed at the discharge chute of the drier to automatically register <br /> or indicate the temperature of the heated aggregates. Provide device in full <br /> view of the plant operator. <br /> 3. Heating of Asphalt Binder — Provide heating so the temperature of the <br /> asphalt binder does not exceed the maximum recommended by the asphalt <br /> binder manufacturer nor be below the minimum temperature required to <br /> maintain the asphalt binder in a homogeneous state. Provide method to <br /> heat the asphalt binder in a manner that will avoid local variations in heating <br /> and provide a continuous supply of asphalt binder to the mixer at a uniform <br /> average temperature with no individual variations exceeding 25°F. Also, <br /> when a WMA additive is included in the asphalt binder, the temperature of <br /> the asphalt binder shall not exceed the maximum recommended by the <br /> manufacturer of the WMA additive. <br /> 4. Sampling and Testing of Mineral Materials—Provide HMA plant equipped <br /> with a mechanical sampler for the sampling of the mineral materials meeting <br /> the requirements of Section 1-05.6 for the crushing and screening operation. <br /> Provide for the setup and operation of the field testing facilities of the City <br /> as provided for in Section 3-01.2(2). 1 <br /> 5. Sampling HMA — Provide for sampling HMA by one of the following <br /> methods: <br /> a. A mechanical sampling device attached to the HMA plant. <br /> b. Platforms or devices to enable sampling from the hauling vehicle <br /> without 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 release <br /> agent. i <br /> Watermain Replacement"U" Division 5—SURFACE TREATMENTS October 1, 2019 <br /> AND PAVEMENTS <br /> WO No.—UP3698 SP-150 I <br />
