PRODUCT DLSCRIPTION 

(e New Hardware or (' Modification to 

Significant Mod1ficat1on Existing Hardware 

The MASH FLEAT terminal Is a flared W-beam guardrai l terminal consisting of: an impact head asse mbly a 

breakaway cabl e anchorage system with a ground strut, three (3 ) rail sections, and eight (8) posts The terminal 

is installed with a straight flare of 3 ft (0.9 m) offset over a length of 39.6 ft (12.1 m) 

The MASH FLEAT impact head assembly Is 6.9 ft (2.1 m) long, consisting of an impact head and an attached 

guide chute that partially encloses the rail. Inside the impact head is a deflector plate which, together w ith the 

kinker beam, sequentially kinks the guardrail as it is fed through the impact head, thu s dissipating the kinetic 

energy of the impacting vehicle 

The anchorage system consists of: an end post (Post 1) and a hinged Post 2 connected with a ground strut, a 

cable anchorage assembly to transmit the force from the rail to the end post and its foundation, and a cable 

release bracket that disengages the cable anchor from the rail upon impact by the end of the guide chute. Post 

1 has a 2.4 ft (0.7 m) long top portion constructed of 6 in. x 6 in. x 0.125 in. ( 152 mm x 152 mm x 3 mm) steel 

tube and a 6 ft ( 1.8 m) long bottom section constructed of W6 x 15 steel I-beam. The top and bottom sections 

are pinned together by a 0.625 in. (16 mm) diameter bolt and nut. Post 2 (the same for Post 3) consists of one 

2.8 ft (0.9 m) long top portion and a 6 ft ( 1.8 m) long bottom portion, both constructed of W6x9 steel I-beam 

and pinned together by a 0.75 in. ( 19 mm) diameter bolt and nut. The upstream end of the cable anchor is 

attached to Post 1 through a 0.625 in. (16 mm) thick, 8.0 in. (203 mm) square steel bearing plate. The 

downstream end of the cable anchor is attached to a cable release bracket designed to disengage from the rail 

section upon impact by the end of the guide chute. The ground strut Is mounted to a second 0.625 in. (16 mm) 

bolt through Post 1 and by the 0.75 in. (19 mm) hinge bolt in Post 2. 

All guardrail sections consist of 1 2-ga W-beam rail sections. The end section is 12.5 ft (3.8 m) long with hole 

patterns for rail splices and attachment of the cable release bracket, as well as slots to initiate kinking. The 

second rail section is 10.4 ft (3.2 m) long so that the next splice is mid-span between Posts 5 and 6. The third rail 

section is 13.5 ft (4. 1 m) long, followed by standard 12.5 ft (3.8 m) rail sections. With the exception of the first 

splice, all splices are mid-span between posts. 

There are eight (8) posts in the terminal section. In addition to the breakaway end post, posts 2 and 3 are 

hinged posts. Posts 4 through 8 are standard 6.0 ft (1.8 m) W6 x 9 steel posts and can utilize 8.0 in (203 mm) or 

12 in. (305 mm) deep wood or recycled plastic blackouts. Post spacing between Posts 1 and 2 and Posts 2 and 

3 is 6.25 ft ( 1.9 m), which is then reduced to 50 in. ( 1 .3 m) through the rest of the terminal from Posts 3 through 

8. The post spacing then reverts back to the standard 6.25 ft (1 .9 m) beyond the terminal. 

The MASH FLEAT Terminal may utilize powder coated or painted rail sections, impact head and other 

components. Reference attachment Powder Coated Report 08/ 27/ 2009.

The vehicle pushed the impact head down 

the length of the guardrail past the Post 4, 

at which point the rail began to buckle and 

the vehicle began to yaw clockwise. The 

vehicle then impacted the rail at the bend at 

the passenger door on the driver side 

before coming to a stop next to the rail on 

the field side, 48.1 ft ( 14.7 m) from the point 

of initial impact. The test vehicle sustained 

moderate damage to the front end and to 

the driver side with a maximum occupant 

compartment deformation of 3 in. (76 mm). 

The vehicle remained upright and did not 

leave its lane. The test article received 

extensive damage from post 1 through post

GENERAL NOTES: 

1. All bolts. nuts, cable assemblies, cable anchors and bearing plates shall be galvanized. 

2. The lower sections or the Posts 1, 2 & 3 shall not protrude more than 4 in above the 

ground {measured along a 5' cord ). Site grading may be necessary to meet this requirement 

3. The lower sections or the hinged posts should not be driven with the upper post attached . 

If the post Is placed in a drilled hole, 1he backfill material mus1 be satisfactorily compac1ed to 

prevent settlement. 

4. When competent rock is encounlered, a 12" 0 post hole. 20 in. deep cored into the rock 

surface may be used if approved by the engineer for Posts 1 and/or 2. Granular material will 

be placed in the bottom of the hole, approx1m;,tely 2 5" deep to provide drainage The first 

post can be field cut to length, placed in the hole and backfilled with suitable backfill. The so,I 

plate may be trimmed if required. 

5. The breakaway cable assembly must be taut. A locking device {vice grips or channel lock 

pliers) should be used to prevent the cable from twisting when tightening nuts.
