THE LENGTH OF THE TENSIONED CABLE NECESSARY TO INSTALL A FUNCTIONAL ANCHOR SYSTEM SHALL BE INCLUDED IN ITEM 606, CABLE BARRIER WITH CONCRETE LINE POST FOUNDATION. INSTALLATION SHALL BE AT THE LOCATIONS SPECIFIED IN THE PLANS, IN ACCORDANCE WITH THE MANUFACTURER'S SPECIFICATIONS. SYSTEMS SHALL HAVE A MAXIMUM DEFLECTION OF 8 FEET AND THE MAXIMUM LONGITUDINAL DISTANCE BETWEEN POSTS SHALL BE 15 FEET. INSTALLATION WILL BE A FOUR CABLE HIGH TENSION SYSTEM INSTALLED IN SOCKETED POSTS FOUNDATION WITH A FOUR FOOT WIDE "NO MOW STRIP". DELINEATE THE CABLE BARRIER USING TYPE 6 BARRIER REFLECTORS PER ITEM 626 OR USING FLEXIBLE POSTS PER ITEM 620 AS CALLED FOR IN THE PLANS OR DIRECTED BY THE ENGINEER. ANCHOR TERMINAL STRUTS SHALL BE COVERED COMPLETELY ON BOTH SIDES WITH YELLOW TYPE J, ASTM D 4956 TYPE XI REFLECTIVE SHEETING, PER CMS 730.193. TRANSITIONS TO W-BEAM GUARDRAIL ARE NOT ALLOWED. REFER TO MANUFACTURER FOR MAXIMUM OFFSET FROM BREAK POINT. TORPEDO OR BULLET SPLICES ARE NOT ALLOWED. ALL CABLE SPLICES SHALL BE A SWAGED OR OPEN BODY DESIGN THAT ALLOWS FOR ANNUAL INSPECTION BETWEEN THE WEDGE AND STRANDS OF CABLE. POSTS ARE SET IN SOCKETED CONCRETE FOUNDATIONS AND SHALL NOT BE PERMANENTLY INSTALLED UNTIL THEIR RESPECTIVE RUNS OF TENSIONED CABLE GUARDRAIL ARE READY FOR FINAL CONNECTION TO THE END TERMINAL ASSEMBLY. THE CONTRACTOR SHALL REPLACE ANY POSTS DAMAGED DURING INSTALLATION AS DETERMINED BY THE ENGINEER AT NO ADDITIONAL COST TO THE STATE.~~ Designer Note: High tension cable barrier systems shall only be installed to meet the requirements of Location and Design Manual Section 601.2 Median Barrier Warrants. The most current approved products and models are updated regularly online, as such, individual products should generally not be listed on the plans. Cable barrier should be delineated using Type 6 Barrier Reflectors per Item 626 or using flexible posts per Item 620 and the delineation should be itemized and paid for under its respective item number. Designer should look at the entire corridor before selecting which side of the median the cable will be installed on. At breaks in the runs of cable such as turnarounds the layout of the cable should limit the gating potential of the cable end treatments. Installing the end treatments behind the trailing bridge parapets can eliminate the gating part of the end treatments. When overlapping cable runs eliminate all of the gating part of the end treatments. Review Figure 602-3 and 602-4 of L&D Vol. 1 for appropriate layouts.
