The rapid cure allows minimum traffic delay when tested under California Test 434. 86-5.01A(4) Installation Details Install loop conductors without splices and end in the nearest pull box. Seal the open end of the cable jacket or tubing similar to splicing requirements to prevent water from entering. Do not make final splices between loops and lead-in cable until loop operations under actual traffic conditions are authorized. Splice all loop conductors for each direction of travel for the same phase of a traffic signal system, in the same pull box, to a detector lead-in cable that runs from the pull box adjacent to the loop detector to a sensor unit mounted in the controller cabinet. End all loop conductors in a pull box or a terminal strip in the cabinet. Identify and band conductors for inductive loop installations. Band conductors, in pairs, by lane, in the pull box adjacent to the loops and near the end of the conductors in the cabinet. Bands must comply with section 86-2.09. If HMA surfacing is to be placed, install loop conductors before placing the uppermost layer of HMA. Install conductors in a compacted layer of HMA immediately below the uppermost layer. Install conductors as shown, except fill the slot with a sealant flush to the surface. When cutting loops: 1. Saw cuts must be cleaned with compressed air to remove all excess moisture and debris. For repairing damaged saw cuts, all loose spalled material must be cleaned away from the saw cut, chipping back to sound asphalt concrete or concrete pavement, and cleaned away from the loop wires. 2. Residue from slot cutting activities must not be allowed to flow across shoulders or lanes occupied by traffic and must be removed from the pavement surface before residue flows off. Dispose of residue from slot cutting activities. 3. Before setting, surplus sealant must be removed from the adjacent road surface without using solvents. 86-5.01A(5} Preformed Inductive Loops Preformed inductive loops must be the type shown. The loop must be 6-foot square unless otherwise shown. The loop must consist of 4 turns of No. 16, or larger, wire with Type THWN or TFFN insulation. Encase the loop wires in 3/8-inch, minimum, Schedule 40 or Schedule 80 PVC or polypropylene conduit and seal the conduit to prevent the entrance of water and the movement of wires within the conduit. The loop wires from the preformed loop to the adjacent pull box must be twisted together into a pair, at least 2 turns per foot, and encased in Schedule 40 or Schedule 80 PVC or polypropylene conduit between the preformed loop and the adjacent pull box or detector handhole. The lead-in conduit must be sealed to prevent the entrance of water at the pull box or hand hole end. In new roadways, place the preformed loops and lead-in conduits in the base course with the top of the conduit flush with the top of the base. Cover with HMA or concrete pavement. Protect preformed loops and lead-in conduits from damage before and during pavement placement. In new reinforced concrete structure decks, secure the preformed loops to the top of the uppermost layer of reinforcing steel using nylon wire ties. Hold the loop parallel to the structure deck by using PVC or polypropylene spacers where necessary. Place conduit for lead-in conductors between the uppermost 2 layers of reinforcing steel. Do not install preformed inductive loops in existing structure decks. Preformed loop installation in existing pavement must comply with the following: 1. Preformed loops and lead-in conduits must be placed in 1-1/4-inch-minimum-width slots cut into the existing pavement. The top of the conduit must be 2 inches, minimum, below the top of pavement. 938 SECTION 86 ELECTRICAL SYSTEMS 2. Slots in asphalt concrete pavement must be filled with elastomeric or hot-melt rubberized asphalt sealant. 3. Slots in concrete pavement must be filled with epoxy sealant or hot melt rubberized asphalt sealant. 86-5.01 B Magnetic Detectors Cable from the pull box adjacent to the magnetic detector sensing element to the field terminals in the controller cabinet must be the type specified for inductive loop detectors. 86-5.01 C Microwave Vehicle Detection System (Side Fire) Reserved 86-5.01 D Emergency Vehicle Detector System Reserved 86-5.02 PEDESTRIAN PUSH BUTTON ASSEMBLIES Housing must be either die-cast or permanent mold-cast aluminum. Assembly must be rainproof and shockproof in any weather condition. The switch must be a single-pole, double-throw switching unit with screw-type terminals rated 15 A at 125 V(ac), and must have~ 1. Plunger actuator and a U frame to allow recessed mounting in the push button housing 2. Operating force of 3.5 lb 3. 1/64-inch maximum pre-travel 4. 7/32-inch minimum overtravel 5. 0.0004-to 0.002-inch differential travel 6. 2-inch-minimum-diameter actuator Wherever a pedestrian push button is attached to a pole, shape the housing to fit the pole curvature and secure. Include saddles to make a neat fit if needed. Wherever a pedestrian push button is mounted on top of a 2-1/2-inch-diameter post, fit the housing with a slip-fitter and use screws for securing rigidly to post. Pedestrian push button signs must be porcelain-enameled metal or structural plastic. Install the push button and the sign on the crosswalk side of the pole. Point arrows on the push button signs in the same direction as the corresponding crosswalk. Attach the sign on a Type 8 push button assembly. For Type C pedestrian push button assembly, mount the instruction sign on the same standard as the push button assembly, using 2 straps and saddle brackets. Straps and saddle brackets must be corrosion-resisting chromium nickel steel and comply with ASTM A 167, Type 3028. Theftproof bolts must be stainless steel with a chromium content of 17 percent and a nickel content of 8 percent. 86-6 LIGHTING 86-6.01 HIGH-PRESSURE SODIUM LUMINAIRES High-pressure sodium luminaires must be the enclosed cutoff type. Each luminaire must consist of a housing, a reflector, a refractor or lens, a lamp socket, an integral ballast, a terminal strip, and a lamp. Housing must be manufactured from aluminum. Painted or powder-coated housing must withstand a 1 , 000-hour salt spray test as specified in ASTM 8 117. Other metal parts must be corrosion resistant. Each housing must include a slip fitter that can be mounted on a 2-inch pipe tenon and can be adjusted 5 degrees from the axis of the tenon. Clamping brackets of the slip-fitter must not bottom out on the housing bosses when adjusted within the ± 5 degree range. 939
