PRODUCT DESCRIPTION 

(e New Hardware or 

• Significant Modification

(' Modification to 

Existing Hardware 

The MAX-TensionTM Median Guardrail Terminal System (MAX-Median) is a re-directive gating end terminal for 

double sided corrugated W-beam barrier systems in median or roadside configurations. The MAX-Median 

system utilizes tensioned cables, telescoping panels, and a cutting tooth to absorb the kinetic energy and 

safely contain or redirect impacting vehicles. The system is comprised of a friction based energy absorbing 

impact head, two tension cables, two support cables, two releasable posts (post 1 and 2), a ground anchor 

assembly, a panel coupler, and an energy absorbing panel coupler with integrated cutting tooth used in 

conjunction with standard AASHTO 12 Gauge guardrail panels, posts, blockouts, and hardware. The system 

length is approximately 27ft [8.2ml and has an effective length of approximately 50 ft [15.25ml, with the 

anchor assembly extending forward approximately 4 ft [1 .2ml. The Length of Need is at Post 3, 9ft 4in [2.86ml 

downstream of the first post. 

The MAX-Median can be applied directly to double sided W-Beam guardrail systems at, or transitioned to, 

31" rail height with panels and post spacing configured at mid-span splice. Transitions to strong post W-beam 

guardrail systems or other barriers where the splice is not mid-span can be accomplished using 3ft 1 1 /2in 

[0.95ml, 9ft 4 1 /2in [2.85ml, or 15ft 7 1 /2in [4.75ml panels after the MAX-Median system (minimum 50ft 

[15.25ml downstream of the first post) in accordance with Federal, State, and local standards. Transitions to 

other barrier systems such as thrie beam or rigid bridge or roadside barriers shall be in accordance with 

Federal, State, and local requirements and attached after the MAX-Median system (minimum 50ft [15.25ml 

downstream of the first post). 

The MAX-Median can be applied with a Oto 2 ft[610mm] offset in accordance with FHWA recommendations. 

The MAX-Median may be configured using wood or composite blockouts with Sin [200mm] depth. 

Reference Enclosure A, "MAX-Tension Median Guardrail End Terminal System TL-3 Configurations 

Justifications". 

The MAX-Median may utilize standard AASHTO 8.Slb/ft or 9lb/ft line posts after post number two. It may 

also utilize standard AASHTO M-180 12 Gauge panels in 12ft-6in [3.8ml or 25ft [7.6ml lengths within the 

system. Reference Enclosure A. The MAX-Median may be painted, stained, or powder coated on surfaces that 

do not effect the function of the system in place of or in addition to galvanizing. Reference Enclosure A for 

details regarding surfaces that may be coated and the components or surfaces that may not. 

Any delineation pattern, tape, or decal may be placed on the Delineation Bracket attached to the MAXMedian impact head. In addition, variations of brackets may be utilized with the MAX-Median (Enclosure A). 

The MAX-Median may display identification decals, tags, or stamps for product identification, component 

tracking and quality control. The identification method and location shall not effect the capacity, function, or 

performance of the MAX-Median. Reference Enclosure A. 

A minor modification to a component is proposed in Enclosure A. The section titled "Stamped vs. Welded 

Traffic Side Slider" details an alternative manufacturing method for the coupler where it is stamped from a 

single sheet of steel instead of welding two components together. This component may be fabricated in either 

configuration with no effect on the capacity, function, or performance of the MAX-Median. 

Manufacturing drawings may be adjusted to ensure manufacturing capability and consistency with MASH 

tested and certified product.

INTENDED USE 

The MAX-TensionTM Median Gua(drail End Terminal (MAX-Median) is a re-directive, gating tension-based end terminal 

for double sided corrugated W-Beam barrier systems in median or roadside configurations. It can be used to protect motorists 

from unforgiving terminations of longitudal barriers. The MAX-Median system absorbs the energy and gradually decelerates 

an impacting vehicle when impacted head-on and contains and redirects a vehicle during side impacts. The beginning of length 

of need is at post 3. The MAX-Median system intergrates directly into a corrugated W-Beam guardrail system. 

The system consists of a friction based energy absorbing impact head, two tension cables and two support cables, releasable post 

I and 2, a ground anchor assembly, a panel coupler, and an energy absorbing panel coupler with integrated cutting tooth used in 

conj unction with standard AASHTO 12 gauge guardrail panels, posts, blockouts, and hardware. The system can be installed on 

any guardrail system at or transitioned to a rail height of 31" [787] with mid-span splices. Contact the manufacturer for further 

infonnation and installation instructions. 

APPROVALS 

The MAX-Tension Median system has been fully tested in conformance with MASH Test Level 3 and is eligible 

for Federal reimbursement.
