发明名称 Pad for supporting a utility access conduit and method for installing same
摘要 The present invention relates to a pad which supports a utility access conduit in a roadway and permits relative movement between the conduit and the roadway without damaging the seal between them and which supports vehicular traffic for a time comparable to the life of the roadway itself, without the occurrence of any dipping in the vicinity of the access conduit. This is accomplished with a rectangular block or rubber or similar compressibly resilient elastomeric material which has an opening passing through it that snugly engages the access conduit. The invention also relates to a method for installing the pad in either a new or existing roadway.
