IN I <br /> I <br /> 73 IN I , moi- r` - ' _ , , �, :. <br /> � .: ,. . <br /> 12 <br /> IN <br /> IN <br /> 3304 Transportation of the Mixture. <br /> Transport the mixture in tight vehicles previously cleaned of all foreign material . After <br /> cleaning, thinly coat the inside surface of the truck bodies with soapy water or an asphalt release <br /> agent as needed to prevent the mixture from adhering to the beds . Do not allow excess liquid to <br /> pond in the truck body. Do not use diesel fuel or any other hazardous or environmentally <br /> detrimental material as a coating for the inside surface of the truck body. Cover each load during <br /> IN cool and cloudy weather and at any time it appears rain is likely during transit with a tarpaulin or <br /> waterproof cover meeting requirements of 320 - 5 . 4 . <br /> 3304 Preparation of Application Surfaces . <br /> 330-8 . 1 Cleaning : Prior to the laying of the mixture, clean the surface of the base or <br /> pavement to be covered of all loose and deleterious material by the use of power brooms or <br /> blowers , supplemented by hand brooming where necessary. <br /> 3304 . 2 Patching, Leveling, and Overbuild Courses : Where an asphalt mix is to be <br /> placed on an existing pavement or old base which is irregular, and wherever the plans indicate , <br /> bring the existing surface to proper grade and cross -section by the application of patching, <br /> leveling, or overbuild courses . <br /> 330-8.3 Application Over Surface Treatment : Where an asphalt mix is to be placed <br /> FF <br /> over a newly constructed surface treatment, sweep and dispose of all loose material from the <br /> paving area. <br /> 3304 .4 Coating Surfaces of Contacting Structures : Paint all structures which will be <br /> in actual contact with the asphalt mixture, with the exception of the vertical faces of existing <br /> pavement, curbs and gutter, with a uniform coating of asphalt binder to provide a closely bonded, <br /> watertight joint . <br /> 3304 . 5 Tack Coat : <br /> 3304 .5 . 1 Tack Coat Required : Apply a tack coat, as specified in Section 300 , <br /> on existing pavement structures that are to be overlaid with an asphalt mix and between <br /> successive layers of all asphalt mixes . <br /> 330-8 . 5 .2 Tack Coat at Engineer' s Option : Apply a tack coat on the following <br /> surfaces only when so directed by the Engineer : <br /> 1 . Freshly primed bases . <br /> 2 . Surface treatment. <br /> 330-9 Placing Mixture. <br /> 330-9 . 1 Requirements Applicable to All Types : <br /> 330-9. 1 . 1 Alignment of Edges . Lay all asphalt concrete mixtures , including <br /> leveling courses , other than the pavement edge just adjacent to curb and gutter or other true <br /> edges , by the stringline method to obtain an accurate , uniform alignment of the pavement edge . <br /> Control the unsupported pavement edge to ensure that it will not deviate more than ± 1 . 5 inches <br /> from the stringline . <br /> 330-9 . 1 .2 Temperature of Spreading : Maintain the temperature of the mix at the <br /> time of spreading within the master range as defined in 330 - 6 . 3 . The minimum frequency for <br /> taking mix temperatures on the roadway will be as indicated in 330 -6 . 3 . Any load or portion of a <br /> load of asphalt mix on the roadway with a temperature outside of the master range shall be <br /> rejected for use on the project. The Engineer will be immediately notified of the rejection . <br /> 330-9 . 1 .3 Rain and Surface Conditions : Immediately cease transportation of <br /> asphalt mixtures from the plant when rain begins at the roadway. Do not place asphalt mixtures <br /> - 72 - <br /> FPID ( S ) : 423186 - 1 - 58 - 01 <br />
