CITY OF EVERETT SPECIAL PROVISIONS <br /> 5-04.3(3) Equipment <br /> 5-04.3(3)A Mixing Plant <br /> Provide plants used for the preparation of HMA conforming to the following <br /> requirements: <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. <br /> Provide the circulating system for the asphalt binder designed to ensure <br /> proper and continuous circulation during the operating period. Provide a <br /> valve for the purpose of sampling the asphalt binder placed in either the <br /> storage tank or 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 <br /> asphalt binder feed line at a location near the charging valve at the mixer <br /> unit and location convenient and safe for access by Inspectors. Provide <br /> plant equipped with an approved dial-scale thermometer, a mercury <br /> actuated thermometer, an electric pyrometer, or another approved <br /> thermometric instrument placed at the discharge chute of the drier to <br /> automatically register or indicate the temperature of the heated <br /> aggregates. Provide device in full 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 <br /> asphalt binder manufacturer nor be below the minimum temperature <br /> required to maintain the asphalt binder in a homogeneous state. Provide <br /> method to heat the asphalt binder in a manner that will avoid local <br /> variations in heating and provide a continuous supply of asphalt binder to <br /> the mixer at a uniform average temperature with no individual variations <br /> exceeding 25°F. Also, when a WMA additive is included in the asphalt <br /> binder, the temperature of the asphalt binder shall not exceed the <br /> maximum recommended by the manufacturer of the WMA additive. <br /> 4. Sampling and Testing of Mineral Materials — Provide HMA plant <br /> equipped with a mechanical sampler for the sampling of the mineral <br /> materials meeting the requirements of Section 1-05.6 for the crushing and <br /> screening operation. Provide for the setup and operation of the field <br /> testing facilities of the City as provided for in Section 3-01.2(2). <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.
