Provide the circulating system <br />for the asphalt binder designed to ensure proper and continuous circulation <br />during the operating period. Provide a valve for the purpose of sampling the <br />asphalt binder placed in either the 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 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 equipped <br />with an approved dial-scale thermometer, a mercury actuated thermometer, an <br />electric pyrometer, or another approved thermometric instrument placed at the <br />discharge chute of the drier to automatically register or indicate the temperature <br />of the heated aggregates. Provide  device in full view of the plant operator. <br />3. Heating of Asphalt Binder – Provide heating so the temperature of the asphalt <br />binder does not exceed the maximum recommended by the asphalt binder <br />manufacturer nor be below the minimum temperature required to maintain the <br />asphalt binder in a homogeneous state. Provide method to heat the asphalt <br />binder in a manner that will avoid local variations in heating and provide a <br />continuous supply of asphalt binder to the mixer at a uniform average <br />temperature with no individual variations exceeding 25°F. Also, when a WMA <br />additive is included in the asphalt binder, the temperature of the asphalt binder <br />shall not exceed the maximum recommended by the manufacturer of the WMA <br />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 the <br />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 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 hauling <br />equipment with HMA. Do NOT use petroleum derivatives or other coating material <br />that contaminate or alter the characteristics of the HMA. For live bed trucks, the <br />conveyer shall be in operation during the process of applying the 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 finishing <br />courses of HMA plant mix material in lane widths required by the paving section <br />shown in the Plans.
