INTENDED USE

The Pinned Cross-Bolt F-Shape Concrete Traffic Barrier is a MASH TL-3 system intended for 

installation along roadsides where a traffic barrier system is required, either permanent or 

temporary. The system consists of 13-ft 11⁄2-in (4-m) long precast concrete f-shape traffic 

barriers, for a total installation length of 170-ft 71⁄4-in (52-m). The precast concrete traffic 

barrier sections are 32-in (813-mm) high and 23.5-in (597-mm) wide at the base. The Barrier 

was pinned (anchored) to pavement via precast anchor pockets for lateral restraint on 

asphalt pavement, traffic side only, with three (3) threaded bolts 3/4-in (19-mm) diameter, 

12-in (305-mm) in length, using a 3/4-in (19-mm) nut and a 7/8-in (22-mm) plate washer 

with a plastic insert (ReDD®)for the 3/4-in (19-mm) diameter anchor rods. Each anchor was 

installed in holes drilled 9 degrees from plumb (vertical), 7-in (178-mm) deep X 3/8-in (10-

mm) diameter into 3.5-in (89-mm) thick asphalt pavement and subbase, then secured 

with an epoxy system as per the manufacturer's instructions. The threaded rod is epoxied 

6-in into the asphalt and subbase. Test artical dynamic deflection is 1-in (25-mm) for 1100C 

and 2-in (50.8-mm) for 2270P. 

Test article exhibited concrete spalling at barrier joints and at toe of barrier, and, scuffing 

on the traffic face of the precast concrete traffic barrier at the impact site, including 

spalling of anchor pockets. There was no observed damage to the anchor bolts 

individually from both MASH crash tests 3-10 or 3-11. 

APPROVALS

The Pinned Cross-Bolt F-Shape Concrete Traffic Barrier has been fully tested in compliance 

with MASH, 2016 Test Level 3 and is determined eligible for reimbursement by the FHWA.
