trench. All cuts shall be accomplished in a single pass with a circular pavement cutting saw.
3. The trench shall be blown free of debris and moisture after the trench has been cut. If the loop wire is not immediately installed the Contractor shall install either a wood or other filler, approved by the Royal Commission, to prevent the slot from collapsing. If a curb is proposed for construction where the loops are being installed, a conduit shall be installed through the curb below the roadway level and terminate in the access channel.
4. The wire forming the loop shall be continuous throughout its length and installed without splices. The loop wire shall extend from the trench to the nearest handhole. At this point they shall be sealed for future splicing to loop detector leads.
5. The loop detector wire shall be installed in the following manner. After the trench is blown free of debris and moisture, the turns of wire shall be laid in the slot so that there are no kinks or curls, and no straining or stretching of the insulation around the corners of the slot. A piece of wood with rounded corners shall be used to seat the wire in the bottom of the trench. After the wire is placed, it shall be rechecked for slack, raised portions, andlor tightness. if any of the foregoing are found, they shall be corrected.
6. The two wires from the slot, which form the lead-in wires, shall be twisted together with a minimum of seven turns per 300 mm from the loop to the nearest handhole.
7. The completed loop wire shall be checked for continuity using a suitable tester that will not exceed the voltage rating of the lead insulation.
8. The Contractor shall perform a resistance test on the loop wire to determine that the resistance to ground is ten megohms or greater. If the resistance to ground, prior to placing the sealant is less than ten megohms, the wire should be checked for insulation damage. The Contractor shall make such corrective measures as necessary until the desired readings are obtained.
9. The channel shall be sealed with joint sealant (Bitumen 85125 supplied by National Trading Establishment, P.O. Box 5044 Jeddah. Tel No. 02-672 3308) applied in accordance with the manufacturer's instructions. The sealer shall not be placed in the channel during precipitation of any kind. The Contractor shall ensure that the channel is completely filled with the sealer and that there are np air bubbles in the sealer below the surface. The sealer shall be placed in the channel and not on the roadway. Any sealer which is accidentally applied to the roadway shall be removed. The Contractor shall ensure that the sealer is sufficiently hardened before allowing traffic to move over the area.
10. At those locations where the saw cuts are in a roadway that slopes and the sealant runs and puddles, the Contractor shall, starting at the low end, place the sealant and then place a 50 mm wide strip of masking tape on the roadway surface over the saw cut to contain the sealant.
