  52. 52. TAU-II
  53. 53. FOUNDATION OPTIONS Chart is in QPL 544-0029 Vendor Drawings
  54. 54. FOUNDATION OPTIONS This is not an acceptable pad – asphalt placed over compacted dirt.
  55. 55. CONCRETE FOUNDATIONS 8” threaded rod w/ 6” embedment
  56. 56. ASPHALT FOUNDATIONS 18” threaded rod w/ 16” embedment
  57. 57. ANCHOR EMBEDMENT -Chemical or mechanical anchors are acceptable. -Most common method is using all-thread rod & epoxy. - For a concrete pad, ¾” x 8” threaded rod is used with an embedment depth of 6” in the pad - For asphalt foundations, a ¾” x 18” threaded rod is used with an embedment depth of 16” in the asphalt. -For any anchors in the concrete barrier wall, ¾” mechanical anchors (wedge bolts) are acceptable. -Proper anchor installation procedures are key – dust is blown out of holes; generous amount of epoxy put into holes; epoxy given ample time to cure before tightening, etc. -Not all adhesives listed under QPL 937 HV Type are acceptable. Manufacturer publishes periodic list of those evaluated and found acceptable per manufacturer’s requirements.
  58. 58. ANCHOR EMBEDMENT DEPTH Threads should not extend more than ¼” above the top of the nut when the nut is tight against the backstop ground plate.
  59. 59. ANCHOR EMBEDMENT DEPTH Nuts are not torqued down. No evidence of epoxy flooding out around bolt holes which could indicate not enough epoxy in holes.
  60. 60. ANCHOR EMBEDMENT DEPTH Properly installed front cable anchor plate. Note some epoxy flowing out of holes. No more than ¼” of threads extending above nuts.
  61. 61. CARTRIDGE PLACEMENT Chart is in QPL 544-0029 Vendor Drawings
  62. 62. CARTRIDGE PLACEMENT Type A Cartridge – holes towards the front Type B Cartridge
  63. 63. CARTRIDGE PLACEMENT The writing on the cartridge should face up and is to be legible when standing behind the crash cushion looking towards the nose.
  64. 64. CARTRIDGE PLACEMENT The TAU Configuration chart is printed on the bottom side of each cartridge
  65. 65. SLIDER PANELS & END PANELS End Panel Slider Panel The forward panel overlaps the rearward panel so the forward panel slides over and back .
  66. 66. SLIDER PANELS & END PANELS The rearward panel is “on top” of the forward panel. When impacted, the attenuator will telescope rearward.
  67. 67. SLIDER PANELS & END PANELS The gap between the slider panels should not exceed 3/4”
  68. 68. SLIDER PANELS & END PANELS If you can get your finger in the gap, it’s more than 3/4”!
  69. 69. SLIDER PANELS & END PANELS The end panel is needed even in uni-directional situations to adequately protect the backstop.
  70. 70. BI-DIRECTIONAL CONDITIONS If traffic is approaching the TAU from the backside, a bi- directional transition wing is used to mitigate a reverse impact into the backstop. A “kit” is available for this wing (pictured) or a piece of thrie- beam guardrail and end shoe can be used.
  71. 71. BI-DIRECTIONAL CONDITIONS Drawing is in QPL 544-0029 Vendor Drawings
  72. 72. BARRIER WALL ANCHORING The TAU-II uses two barrier wall anchor tabs – one on each side of the barrier. Whenever the PCB backstop is used on an asphalt foundation, even if not in a bi- directional configuration, the anchor tabs should be used.
  73. 73. TORQUE Slider bolts: 20 ft-lbs If the slider bolts are too tight, the system will not telescope rearward when impacted!
  74. 74. TORQUE Anchors in pad & barrier: On concrete pads – 120 ft-lbs On asphalt pads – 5 ft-lbs Cables: On concrete pads – 500 ft-lbs On asphalt pads – 120 ft-lbs

  91. 91. Inspection for Proper Installation (continued) The SCI SMART CUSHION® is shipped in one piece, fully assembled. During installation the unit only needs to be properly positioned on the pad. Once the SCI SMART CUSHION® is positioned, the holes in the base are used as a template to drill holes to accept the epoxy anchors. SCI SMART CUSHION®
  92. 92. SCI SMART CUSHION® Inspection for Proper Installation (continued) Unit should be centered on the barrier Attenuator should be level and properly oriented on pad CL
  93. 93. Inspection for Proper Installation (continued) Check to make sure all anchors are in place and nuts are tight SCI SMART CUSHION® Proper torque is 125 ft-lbs. On a full collapse, the last set of side panels will telescope 30” beyond the last terminal brace at the rear of the crash cushion.
