Description Text | I have two lengths of Foundation tubes 5’ – from older NDOT plan & 6’ - from the recent Bullnose testing using thrie-beam. Is the 5’ for w-beam still acceptable with the MASH approved loads? Or should I switch to the 6’ only? |

Response | We have been using the 6’ foundation tube for use with the
MGS due to the increased rail height affecting the loading of the anchorage
during initial development of the system. For the bullnose system, we would recommend similar length
foundation tubes for anchoring a free end of the system. Note that the BCT
posts adjacent to the nose of the system use 8’ long foundation tubes as only a
single foundation tube is used for anchorage adjacent to the nose. Thanks |
