� I 1 The paver shall be equipped with automatic screed controls with sensors for 2 either or both sides of the paver.The controls shall be capahie of sen�' ig grade � 3 from an outside reference line, sensing the transverse slc�e of the screed, and � 4 providing automatic signals that operate the screed to maintain the desired 5 grade and transverse slope. The sensor shall be constructed so it will operate , 6 from a reference line or a mat referencing device. ( � 8 The transverse slope controller shall be capable of maintaining the screed at � 9 the desired slope within plus or minus 0.1 percent. The paver shall be equipped 10 with automatic feeder controls, properly adjusted to maintain a unifortn depth of 11 materiai ahead of the screed. 12 � 13 Manual operation uf the screed wdl be permitted in the construction �f � 14 irregularly shaped and minor areas. These areas include, but are not limited to, 15 gore areas, road approaches, lapers and left-turn channelization. 1 16 � 17 When specified in the contract, reference lines for vertical control will be 18 required. Lines shali be placed on both outer edges of the (raveled way of � 19 eacli roadway. Horizontal contr ,I utilizing the reference line will be permitted. � 20 The grade and slope for intermediate lanes shall be controlled automatically 21 from reference lines or by means of a mat referencing device and a slope � 22 control device. When the finish of the grade prepared for paving is superior to 23 the established tolerances and when, in the opinion of the Engineer, further 24 improvement to the line, grade, cross-section, and smoothness can best be 25 achieved without the use oi the reference line, a mat referencing device may be i26 substituted for the reference line. Substitution of the device will be subject to 27 the continued approval oi the Engineer. A joint matcher may be used subject to 28 the approval o( the Engineer. The reference line rnay be removed after the I 29 comp!etion of the first course of HMA when approved by the Engineer. 30 Whenevar the Engine�r determines that any of these methods are failing to 31 provide the necessary vertical control, the reference lines will oe reinstalled hy 1 32 ihe Coniractor. 33 34 The Contractor shall fumish and install all pins, brackets, tensioning devices, " 35 wire, and accessories necessary for satisfactory operation of the automalic � 36 control equipment. 37 � 38 If the paving machine in use is not providing the required finish, the Project 39 Engineer may susper�d work as allowed by Section �-08.6. Any cleaning or � 4U solvent type liquids spiiled on the pavement shall be thoroughly removed 41 before paving proceeds. � 42 43 5-04.3(4) Rollers 44 Rcllers shall be of the steel wheei, vibratory, or pneurnatic tire type, in good f 45 condition and capable oi reversing without backlash. Operation of the roller 46 shall be in accordance witli the manufacturer's recommendations. When 47 ore'ered by the Project Engineer for any roiler planned fur use on the project, � 48 the Contractor shali provide a copy of the manufacturer's recommendation for 49 the use ef that roller for com�action of HMA. The number and weight of rollers 50 shall be su�cienl to compact the mixture in compiiance with the requirements � .51 oi Section 5-04.3(10).
