It is the intent of this specification to describe a Steel Rail Attachment use, to make a portable, plastic energy dispersement cell meet the NCHRP 350 Requirements for Longitudinal Barrier Wall. The 350 Rail Attachment is intended to be used in conjunction with the Yodock Model 2001 and 2001M, in the prevention of vehicular penetration of a work zone.
This specification recognizes the need for a 350 Rail Attachment used with a portable energy dispersement cell to perform some of the functions of concrete barriers used to control, direct, channel and stop vehicular traffic for purposes of aiding in containment and/or safety.
The 350 Rail Attachment is made of steel and wood. It is manufactured to resist corrosion and withstand the impact of vehicular traffic. The 350 Rail Attachment is mounted to the Yodock Traffic Control System Models 2001 and 2001M. It is comprised of two tubular steel box beam rails, which are bolted to two steel brackets, which are placed within the fork lift holes of the Model 2001 and 2001M. The box beam rails are blocked away from the steel brackets using wood blocks. The rail segments are bolted to the steel brackets with grade 5 carriage bolts. Adjacent rails are spliced together using splice tubes and bolted together using grade 8 hex head bolts.
Box Beam: 1830mm, 89 89 6.4mm
Splice Tubes: 280mm, 64 64 6.4mm
Box Beam Connection Bolts: 19mm diameter 230mm long, grade 5 carriage
Wood Blocks: 102 102 254mm
Splice Tube Bolts: 19mm diameter 114mm long, grade 8 hex
Rails Material: A500 grade B tubular steel
Box Beam Functional Length: 1830mm
Each Rail Attachment shall weigh approximately 200 pounds. When installed on the Model 2001 or 2001M, the Rail Attachment shall be interlocked to form a continuous structure. The installed 2001 or 2001M with 350 Rail Attachments must be terminated with an approved method such as an end treatment or a taper. Both the Model 2001 and 2001M with Rail Attachments must be used in accordance with the user's manual.
The Model 2001 with Rail Attachment has met the requirements of NCHRP 350 TL-3. The Model 2001M with Rail Attachment has met the NCHRP 350-2 requirements. Both models with Rail Attachment have been approved by the Federal Highway Administration for use. See FHWA Approval Letter B97.
