Where blast cleaning is used for the removal of painted traffic stripes and pavement markings, the area shall be shielded so that no material from the blasting operation is allowed to enter the area that is open to the public traffic. Sand or other material deposited on the pavement as a result of removing traffic stripes and markings shall be removed as the work progresses. Accumulations of sand or other material which might interfere with drainage or might constitute a hazard to traffic will not be permitted. Traffic stripes shall be removed before any change is made in the traffic pattern. Blast cleaning for removal of traffic stripes shall be feathered out to irregular and varying widths. Pavement markings shall be removed by blast cleaning a rectangular area, rather than just lettering or markings, so the old message cannot be identified. After removal of traffic stripes and pavement markings, a fog seal coat shall be applied in conformance with the provisions in Section 37, Bituminous Seals", of the Standard Specifications and the following: In traffic stripe removal areas, the fog seal coat shall be applied over the traffic stripe removal area and to irregular and varying widths with an average width of 2 feet on each side of the blast cleaned traffic stripe removal area. In pavement marking removal areas, the fog seal coat shall be applied to the blast cleaned rectangular area. Full compensation for fumishing and applying fog seal as specified herein shall be considered as included in the contract price paid per square foot for removal of traffic stripe and pavement marking and no separate payment will be made therefor. Nothing in these special provisions shall relieve the Contractor from his responsibilities as provided in Section 7-1.09, "Public Safety," of the Standard Specifications. TRAFFIC STRIPES AND PAVEMENT MARKINGS. Traffic stripes and pavement markings shall be thermoplastic and shall conform to Section 84-2, "Thermoplastic Traffic Stripes and Pavement Markings," of the Standard Specifications. PAVEMENT MARKERS. Pavement markers shall conform to Section 85 "Pavement Markers" of the Standard Specifications. TRAFFIC DELINEATION. Immediately after any construction operations where traffic delineation is obliterated or when directed by the Engineer, the contractor shall replace all obliterated pavement delineation with temporary delineation during the some work period, and in no case later than 7:30 a.m. following such work period. Temporary delineation consists of reflective traffic line tape applied in pieces not less than 4 inches long nor less than 4 inches wide, spaced no more than 20 feet apart on tangents and no more than 10 feet apart on curves. Apply reflective traffic line tape in accordance with the manufacturer's instructions. Temporary delination must be the some color as the permanent delineation. Remove temporary delineation applied to asphalt concrete patches immediately prior to applying asphaltic emulsion tackcoat for asphalt concrete overlay. Traffic stripes and pavement markings shall conform to Section 84, "Traffic Stripes & Pavement Markings," of the Standard Specifications and these special provisions. Traffic stripes and pavement markings shall be thermoplastic and shall conform to Section 84-2, "Thermoplastic Traffic Stripes and Pavement Markings". The first sentence of Section 84-2.01 "Materials" shall be revised to read: The thermoplastic materials shall conform to State Specification 8010-21C-19. Pavement markers shall conform to Section 85 "Pavement Markers," and these special provisions: Pavement markers shall be placed with rapid set epoxy per Section 95-2.04 of the Standard Specifications. DETECTORS. Detectors shall conform to the provisions in Section 86-5, "Detectors," of the Standard Specifications and these special provisions. Location and layout of detector loops shall be as directed by th City Engineer. CONSTRUCTION MATERIALS: Loop detector lead-in cables shall conform to the provisions in Section 86-5.01A (4), "Construction Materials," of the Standard Specifications and these special provisions. Loop detector lead-in cables shall be Type B, and shall conform to the following: Loop wires in the pull box shall be twisted at a minimum rate of 5 turns per foot, and the splice must be soldered and completely waterproof. Connect one end of the shield to earth ground (at cabinet) and insulate other end with no possible path to earth ground. All spade connectors used to attach to terminals inside the controller cabinet shall be crimped and soldered to the conductor. INSTALLATION DETAILS: Installation details shall conform to the provisions in Section 86-5.01A (5), "Installation Details," of the Standard Specifications and these special provisions. Slots cut in the pavement shall be blown out and dried before installing inductive loop detectors. After conductors are installed in slots cut in the pavement, the slots shall be filled with epoxy sealant conforming to the requirements in Section 95-2.09 "Epoxy Sealant for Inductive Loops," to within 1/8 inch of the pavement surface. The sealant shall be at least 1/2 inch thick above the top conductor in the saw cut. Before setting, surplus sealant shall be removed from the adjacent road surfaces without the use of solvents. In lieu of the epoxy sealant specified above, slots may be filled with either of the following materials: 1. An elostomeric sealant conforming to Section 86-5.01A (5) of the Standard Specifications. 2. Asphaltic Emulsion Inductive Loop Sealant conforming to Section 86-5.01A (5) of the Standard Specifications. Identification of each conductor pair shall consist of labeling the phase and detector slot number (e.g.' - 6J2L, 8J8U, 315U, etc.) in permanent ink on a tag suitable, for such purposes (Stuart Electric Ty Rap, Catalog No. TY5532 or approved equal). If asphalt concrete surfacing is to be placed, the loop detector conductors shall be installed prior to placing the uppermost layer of asphalt concrete... The conductors shall be installed, as shown on the plans, in the compacted layer of asphalt concrete immediately below the uppermost layer. „ Installation details shall be as shown on the plans, except the epoxy sealant shall fill the slot flush to the surface. Detector loops in concrete pads shall be sealed with epoxy sealant. PREEMPTION SYSTEM. The contractor shall provide a fully operational preemption system. The contractor shall furnish and install Opticom 711 (Single Unit) preemption devices as indicated on the signal plans including all cables and mounting hardware. The contractor shall also furnish and install an Opticom 754 phase selector unit in the controller cabinet. Exact preemption hardware mounting placement shall be determined by the Enginee� in the field. The optical detector cable (3-M Optlicom Model 138 or equal) shall have four conductors of AWG #20 (7X28) stranded individually tinned drawn wire to provide signal integrity and transient protection. The individually tinned copper, color -coded insulation shall be as follows: i-01 a. Orange for delivery of opticgj,,,,tect power,( -k) b. Negative return wire for optica etec or powev.;k-) C. Yellow for optical detector signals #1 =i . • •, d. Blue for optical detector signal # *W 3;. TRAFRC SIGNAL INTERCONNECT.hal Interconnect Cable sMll.be six or twelve pair as shown .h the plans and shall confolto the provrj'bnsci ion 8672.08E, "Signal Interconnect Cable," of the Standard S if s an""'these rovisions. The conductors shall be solid #19 AWGaled copper `I> ed airs. The conductors shall be no less than 4 turns a 4 P p r inches for twel .pair cable and 3.5 turns per 14 inches for six pair cable. TER cable shall have a�orrugated copolymer -coated 8 -mil aluminum tape appli longitudinally over rhe core wrap. These cabl(s must meet the requirements of -39 and ANSI/ICEA S-84-608-1988.
