PRODUCT DESCRIPTION I (i' New Hardware \ Modification to 

Existing Hardware 

The Trailing-End Anchorage for 31-in. tall Guardrail (SEW31) is comprised of two timber breakaway cable 

terminal (BCT} posts (PDFOl) set into 72-in. long, ASTM ASOO Grade Bsteel foundation tubes (PTE06) such that 

the top of the BCT timber posts are 32 in. from the ground. The two steel foundation tubes are spaced 75 in. 

apart and are connected at the ground by a Strut and Yoke Assembly (PFP02) with a 10-in. long, ASTM A307 

bolt with nut (FBX16a) and washers (FWC16a) under the head of the bolt and the nut at each foundation tube. 

One end of a BCT Anchor Cable Assembly (FCAOl) was attached to the backside of the Trailing-End Anchorage 

Rail Section (RWM14a) with an Anchor Bracket Assembly (FPAOl). The Anchor Bracket Assembly was attached to 

the Trailing-End anchorage Rail Section with eight 1 1 /2-in. long ASTM A307 hex head bolts and nuts (FBXl 6a) 

with washers (FWCl 6a) under the head of the bolt and the nut. The other end of a BCT Anchor Cable Assembly 

(FCAOl) passed through the hole at the bottom of the end timber BCT post (PDFOl) which contained a BCT Post 

Sleeve (FMM02) and was secured through an ASTM A36 steel BCT Bearing Plate (FPBOl ). The rail is attached to 

the timber BCT posts with standard guardrail bolts or ASTM A307 5/8-in. diameter x 10-ln. long guardrail bolts 

and nuts (FBB03). A 12-gauge, Rounded W-Beam End Section (RWE03a) is attached to the end of the TrailingEnd Anchorage Rall Section (RWM14a). A 6-ft long, standard W6x8.5 (or W6x9) ASTM A992 or A36 steel post 

(PWE06), embedded 40 inches in the ground, is placed 150-in. upstream from the last PDF01 post. 

The Trailing-End Anchorage for 31-in. tall Guardrail should be used where needed to anchor the downstream 

end of guardrail and (1) end-on impacts will not occur or (2) the end terminal is placed outside of the clear zone 

for opposite direction traffic. 

The non-gating, redirective length-of-need of the Trailing-End Anchorage (SEW31) is 375 in. from the centerline 

of the last PDF01 post and includes four 6-ft long, standard W6x8.5 (or W6x9) ASTM A992 or A36 steel posts 

(PWE06) or 6-in. x 8-in. Southern Yellow Pine or White Pine posts (PDE02 or PDE20) contained in a standard 

Midwest Guardrail System (SGR20a-c), which is depicted as the 6th Post in the attached Placement Guidelines 

for Shielding Hazards Near Trailing-End Anchorage. Farther downstream from this post, the Trailing-End 

Anchorage becomes a gating terminal, and guidance for using the Trailing-End Anchorage (SEW31) to shield 

hazards near the Trailing-End Anchorage is provided in the attached Placement Guidelines for Shielding 

Hazards Near Trailing-End Anchorage and described by a working width envelope as follows. Note, the working 

width for the gating terminal was determined by the vehicle trajectory. 

(1) At the last PDF01 post, 125 in. of working width recommended. 

(2) At 225" upstream from the last PDF01 post, 65 in. of working width recommended. 

(3) Linearly interpolate between 125 in. and 65 in. such that for every 3 3/4 in. longitudinally upstream from the 

last PDF01 post, 1 in. less of working width recommended. (e.g., at 75 in. upstream from the last PDFOl post, 

105 in. of working width is needed) 

(4) Linearly interpolate between 65 in. and 60 in. such that for every additional 15 in. longitudinally upstream 

from 225 in. upstream from the last PDF01 post, 1 in. less of working width recommended. (e.g., at 255 in. 

upstream from the last PDFOl post, 63 in. of working width is needed) 

(5) At greater than or equal to 300 in. upstream from the last PDFOl post, 60 in. of working width 

recommended.

CRASH TESTING 

A brief description of each crash test and its result: 

3-37 (2270P) 

Two modified versions of test designation no. 3-37 were 

conducted: (1) test no. WIDA-1 was a modified test no. 3-37 with 

the intent of assessing the end ofthe length-of-need rather than 

maximizing vehicle snag and instability; and (2) test no. WIDA-2 was 

a modified test no. 3-37 performed with an 11 OOC instead of a 

2270P to assess vehicle snag and instability. The results from both 

tests are found in MwRSF report no. TRP-03-279-13. 

In test no. WIDA-1, conducted on May 18, 2012, a 5,172-lb pickup 

truck with a simulated occupant seated in the right-front seat, 

impacted the trailing-end anchorage system, with its rail height set 

to the nominal height of 31 inches, at a speed of63.0 mph and at 

an angle of 26.4 degrees. Impact occurred at the sixth post 

upstream from the downstream end of the terminal. At 0.330 sec 

after impact, the vehicle became parallel to the barrier system with 

a speed of45.3 mph. At 0.406 sec, the vehicle exited the system at 

an angle of4.2 degrees and at a speed of43.5 mph. Exterior vehicle 

damage was moderate. Interior occupant compartment 

deformations were minimal, with a maximum deformation of 3/8 

in., consequently not violating the limits established in MASH. 

Damage to the barrier was extensive, consisting of deformed Wbeam rail and guardrail posts, disengaged rail and wood blackouts, 

contacts marks on guardrail and posts, and fractured timber BCT 

posts. The maximum lateral dynamic barrier deflection was 32 ft ­

6.6 in. The working width ofthe system was 32 ft- 6.6 in. which 

included the barrier dynamic deflection. Maximum lateral vehicle 

intrusion behind the traffic-side face ofthe barrier was 124 in. All 

occupant risk measures were well below recommended values, and 

the test vehicle showed no tendency to roll over. 

In test no. WIDA-2, conducted on June 5, 2012, a 2,916-lb small 

passenger car with a simulated occupant seated in the right-front 

seat, impacted the trailing-end anchorage system, with its rail 

height set to the maximum tolerance of 32 inches, at a speed of 

62.0 mph and at an angle of 25.5 degrees. Impact occurred at the 

mid-span between the second and third posts upstream from the 

downstream end of the terminal. After impact, the vehicle's 

Impacting tire slid under the BCT Anchor Cable and BCT Bearing 

Plate, causing the vehicle to pitch downward and roll toward the 

barrier. At 0.248 sec, the vehicle exited the system and angle of 15.9 

degrees and at a speed of32.2 mph. After exiting the system, the 

vehicle yawed 180 degrees. Exterior vehicle damage was extensive. 

Interior occupant compartment deformations were minimal, with a 

maximum of 1 in., consequently not violating the limits established 

in MASH. Damage to the barrier was also extensive, consisting of 

deformed W-beam rail, guardrail posts bearing plate, and 

foundation tube, disengaged rail and wood blockouts, contact 

marks on guardrail and posts, and fractured timber BCT posts. The 

maximum lateral dynamic barrier deflection was 12 ft - 3.3 in. The 

working width of the system was not determined since the terminal 

gated and the vehicle was not redirected. All occupant risk 

measures were below the maximum values, and the test vehicle 

showed no tendency to roll over.

INTENDED USE 


The trailing-end anchorage system is intended fo r use with any Midwest Guardrail System (SG R20a-c, 

SG R2 1a-b. SGR22a-b, SGR23a-b, SG R28a-f. SGR38a-b. SGR39) or equivalent 3 1" [787) tall W-bcam 

guard rail system. The trailing-end anchorage system has been crash tested under Test Level 3 (TL-3) 

conditions and deemed acceptable nccording to the i\1011110/ for Assessing Safety llardware (MASH) 

performance. The trailing-end anchorage system should be used where needed to anchor downstream encl of 

guard ra i I and (I) end-on impacts wi II not occur or (2) end term inal is placed outside of c I ear zone for opposite 

direction traffic. A length of 150·· (381 O] upstream from the first PDFO 1 post must consist of standard (75'. 

[ 1905]) post spacing guardra il before reduced post spacing may start. 

The non-gating, red irecti ve length-of-need of 1he trailing-end anchorage system is 3 I ·_3·· 19525) from the 

centerline of the last PDr:Ql post and includes four PWE06 or PDE02 or PDE20 posts contnined in a standard 

Mid\\ eSt Guardrail System (SG R20a-c). The trailing-end anchorage system should be used in locations where 

a \\Orking width envelope is described as fo llows: 

I. 	 nt the last PDf-0 I post, 125" [3175] of working width recommended; 

2. 	 at 225" [5715] upstream from the last PDFOI post. 65" [ 1651) of working width recommended: 

3. 	 linearly interpolate between 125" [3 175] and 65"(165 1] such that for every 3~" f95l longitudinally 

upstream from the last PDFOI post, 1·· l25] less of working width recommended (e.g., at 75" 11905] 

upstream from the last PDFO I post, I05'' [2667) of working width is recommended); 

4. 	 linearly interpolate between 65" [1651) and 60" [1 524] such that for every additional 15'' 1381] 

longitudinally upstream from 225" [57 15] upstream from the last PDFO 1 post, I" 125j less of working 

width recommended (e.g., at 255'' [6477 1 upstream from the last PDFOl post. 63'' [1600] of working 

width is recommended); and 

5. 	 at greater than or equa l to 300" [76201 upstream from the last PDl'OI post, 60" (1524] of working 

width recommended.
