Other sealants may be used if approved by th�Engincer. � 3) Nylon or polypropylene rope is not required. ; 4) Loops shall not be installed in rainy weather or at temperntures below d0°. 5'� Loops shall be placed in the sawcut in a clockwise direetion. 6) Homeruns for 6' x 15' loop detectnrs may be run 'in a common sawcut only if they are attached to the same phase. I 7) The !oop sealant shall be applied in accordance with the manufacturer's recommendutions 8) Loop wiie shall be a minim�m size of No. !4 AWG stranded copper, Class B, with chemically cross linked polyethylene type RFIH-RHW insulation rated for a minimum of 600 volts. I 4) l�he area around the wnduit stub-em shall be patchcd with hot mix asphalt concrete if it is greater than 2" in width. I 10) The sawcuts shall be of unifonn depth and any sharp edges, abrasions or ridges shall be removed prior to placing the wirC. I 1) 'The sawcuc de.pth shala be a minimum of 3%z" and shall provide a minimum of 2" cover above the loop I w�ires. 12) 'fln:sava�cuf 5vidth shall be a minimum of 1/4" for the loop and 3/8" for tl�e home run. 131 The s�wc��t shall be cleaned out with a high pressure water stream and then dried with compressed air Ipria�t.�lacing the wire. S4) All splices betwcen the loop wire and the loop lead-in cable shall be soldered and utilize a Scoroh Cast I L'-poxy 82-k31 sptice kit in conformance with Standard Plan 806A. ! i) N'hcn fhc roadw.ay is to be overlaycd as a part of the project, thc loops shall be installed prror to the � !inal ot�r,rlay. 1 ' p 49c.�WeNf3 U_spePewryw¢da Uarid{ivuns yid Assiximcs.Inc.
