PRODUCT DESCRIPTION 

(e New Hardware or 

• Significant Modification 

(' Modification to 

Existing Hardware 

-The Concrete Reactive Tension System Fiber Series (CRTS-F) is a fiber and steel reinforced concrete barrier 

connected end to end with tensioning hinge mechanisms and steel pins. Each barrier segment is 

approximately 39 in (1.0 m] and weighs approximately 1435 lb (650 kg). The barrier is 18 in (460 mm] wide. 

-The CRTS-F system can be utilized with or without VLBs. VLB positioning is configured in accordance with the 

requirements of the barrier application. Typical VLB spacing is 1 in 17 CRTS-F barrier segments or fewer, 

however, some applications may require more. 

-The length of need tests, 3-10 (TTI Crash Test No. 690900-LTS5) and 3-11 (TTI Crash Test No. 690900-LTS6) for 

CRTS-F were performed by Texas Transportation Institute (TTI) and have demonstrated acceptable 

performance in accordance with MASH 2016. 

-Some applications may require a transition to permanent or fixed barrier or other fixed roadside hardware. 

This request for eligibility of reimbursement of federal funds is for a crash worthy transition of CRTS-F to fixed 

barrier systems. 

-The transition consists of typical CRTS-F barrier segments and VLBs anchored to the roadway in a prescribed 

method. A steel transition structure provides the shape transition between the CRTS-F and fixed barrier 

geometries. Steel brackets are used to facilitate the anchorage of CRTS-F segments to the roadway using 

mechanical or adhesive anchors. 

-MASH testing was conducted using a portable safety shaped concrete barrier anchored to the roadway to 

represent a permanent or fixed rigid barrier. To accommodate variations in barrier profiles, the steel transition 

structure may be altered to fit. The steel transition structure shall maintain equivalent or greater structural 

composition and material properties. 

-Markings may be stamped into the steel transition structure for identification, quality assurance, and tracking. 

In some cases, a metal identification tag may be fastened to the barrier. 

CRASH TESTING 

By signature below, the Engineer affiliated with the testing laboratory, agrees in support of this submission that 

all of the critical and relevant crash tests for this device listed above were conducted to meet the MASH test 

criteria. The Engineer has determined that no other crash tests are necessary to determine the device meets 

the MASH criteria.

Results 

3-21 (2270P) 

The CRTS-F Transition was judged to have 

successfully met all of the evaluation criteria 

for MASH Test 3-21 for longitudinal barriers. 

The Transition satisfied the MASH structural 

adequacy criteria for its intended function 

as a longitudinal barrier. The test article 

redirected the 2270P vehicle in a controlled 

manner. The vehicle did not penetrate, 

underride, or override the installation. The 

test article exhibited controlled permanent 

and dynamic deflection in the test. 

All of the occupant risk criteria were 

satisfied in testing the CRTS-F Transition. 

Theoretical OIVs in the longitudinal and 

lateral directions were well below the 

preferred limit of 30.0 ft/s (9.1 m/s). 

Ridedown accelerations in the longitudinal 

and lateral directions were below the 

prefered limit of 15 G. No detached 

components posed a threat to the occupant 

compartment, other vehicles, pedestrians or 

personnel in a work zone. 

There was minimal deformation to the 

occupant compartment of the 2270P 

vehicle. There was no intrusion into the 

occupant compartment. The test vehicle 

remained upright during and after the 

collision with moderate roll and pitch. 

The CRTS-F Transition was judged as 

satisfying the applicable MASH vehicle 

trajectory criteria.

INTENDED USE 

The Concrete Reactive Tension® QuickChange® Moveable Barrier System Fiber Series (CRTS-F) is a MASH TL-3 

longitudinal barrier capable of rapid lateral transfer by a transfer vehicle. The CRTS-F is designed to meet the rigid 

requirements of deployment in moveable barrier applications where positive separation is required, and where lane 

widths and lateral space are limited. 

The CRTS-F is a steel and fiber-reinforced concrete barrier connected end to end with tensioning hinge mechanisms 

and grooved steel pins. Each barrier segment is approximately 39 in [1.0 m] in length and weighs approximately 

1435 lb [650 kg]. The barrier is 18 in [457 mm] wide. Steel variable length barriers (VLB) are used in conjunction 

with the concrete segments. The system is applicable to asphalt or concrete road surface. Some applications may 

require a transition to permanent or fixed barrier or other fixed roadside hardware. 

The CRTS-F transition consists of typical CRTS-F barrier segments in accordance with eligibility letter HSST-l /B277 anchored to the roadway in a prescribed method. A steel transition structure provides the shape transition 

between the CRTS-F and fixed barrier geometries. Steel brackets are used to facilitate the anchorage ofCRTS-F 

segments to the roadway using mechanical or adhesive anchors. 

MASH testing was conducted using a portable safety shaped concrete barrier anchored to the roadway to represent a 

permanent or fixed rigid barrier. To accommodate variations in barrier profiles, the steel transition structure may be 

altered to fit. The steel transition structure shall maintain equivalent or greater structural composition and material 

properties. 

APPROVALS
