13 TB Rev. 3 Page 1 TB of Rev. 3 Page 1 of 4 Concrete Reactive Tension System-Quickchange Moveable Barrier (CRTS-QMB) Specification The Concrete Reactive Tension System-Quickchange Moveable Barrier (CRTS-QMB) is designed to meet the rigid requirements of deployment in moveable barrier applications where positive separation technology is required and where lane widths and lateral space are limited. Description Each barrier element of the CRTS-QMB shall be 32" (810 mm) high, 18" (460 mm) wide and 39" (1000 mm) long (Attachment, Figure 1, B000711). The individual elements shall weigh approximately 1500 pounds (680 kg) and rest on four rubber feet to increase the coefficient of friction between the barrier element and the road surface. The barrier elements are connected in an end-to-end fashion with tensioning hinge mechanisms and steel pins that are at least 1.3 " (33 mm) in diameter. The minimum length of CRTS-QMB to create a longitudinal barrier is 100 feet (30 meters). Each end of the CRTS-QMB must be anchored to the roadway with an anchorage that is capable of reacting a 100,000-pound (450,000 Newton) tensile load in the barrier for NCHRP TL-3 installations or capable of at least a 50,000 pound (225,000 Newton) tensile load in the barrier for an NCHRP TL-2 installation, in order to perform with the minimum deflection characteristics. If the end of the CRTS-QMB is not anchored to the roadway a minimum length of 80 sections must be deployed upstream of the point where minimum deflection is required for a TL-3 system, or 40 sections must be deployed upstream of the point where minimum deflection is required for a TL-2 system.. Minimum deflection characteristics for the CRTS-QMB system are shown in the attached RTS- QMB Deflection Curve.

14 TB Rev. 3 Page 2 of 4 Materials The primary elements of the CRTS-QMB shall be constructed of ASTM, A- 36 steel and high strength concrete. All external steel shall be stainless steel or hot dipped galvanized in accordance with ASTM, A 123. All structural welds shall be continuous. CONSTRUCTION METHODS: Barriers will be manufactured by either the wetcast or drycast methods. Minimum concrete 28-day compressive strength shall be 4,000 psi. All surface voids or rock pockets shall be repaired. Surface bugholes caused by trapped air bubbles shall be permitted. Air entrainment shall be as specified by the ordering agency, +/ %. System Requirements The CRTS-QMB system, when installed in accordance with the manufacturers instructions, shall function as a longitudinal barrier and be able to resist the impact of vehicles in accordance with the National Cooperative Highway Research Program Report 350 (NCHRP 350) Test Level 3. The system shall minimize lateral displacement upon impact. The system shall minimize clearance between barrier hinges, resulting in a nominal metal to metal connection. During impact by an errant vehicle, the tension in the barrier system resists the penetration of the vehicle and limits the lateral displacement of the barrier. Reactive Tension System Variable Length Barriers (RTS-VLBs) shall be added to the length of the CRTS-QMB installation in order to allow a smooth lateral transfer through the Barrier Transfer Machine. The number and location of QVLB units that shall be required will vary depending on specifics of the application, number and degree of curves, changes in elevation, etc.

17 TB Rev. 1 Page 1 of 3 Narrow Steel Shelled-Quickchange Moveable Barrier (NSS-QMB) Specification The Narrow Steel Shelled-Quickchange Moveable Barrier (NSS-QMB) is designed to meet the rigid requirements of deployment in moveable barrier applications where positive separation technology is required and where lane widths and lateral space may be limited, or maximum durability is required. Description The barrier elements shall be 32 (810 mm) high, 39 (1000 mm) in length, and 13 (330 mm) wide. The profile is 13 (330 mm) wide except for a heavy steel base, which shall be 24 (610 mm) wide. The barrier shall allow for the incorporation of a lane line at the intersection of the base and the vertical section. The small protrusion of the base shall provide an audible signal upon contact by an errant vehicle s tire (Attachment Figure 1, B001204). The individual elements shall weigh approximately 1600 pounds (725 kg) and shall rest on four rubber feet to increase the coefficient of friction between the barrier element and the road surface. The barrier elements are connected in an end-to-end fashion with tensioning hinge mechanisms and steel pins that are at least 1.3 " (33 mm) in diameter. Each end of the NSS-QMB must be anchored to the roadway with an anchorage that is capable of reacting a 100,000-pound (450,000 Newton) tensile load in the barrier for NCHRP TL-3 installations or capable of at least a 50,000 pound (225,000 Newton) tensile load in the barrier for an NCHRP TL-2 installation, in order to perform with the minimum deflection characteristics. If the end of the NSS-QMB is not anchored to the roadway a minimum length of 80 sections must be deployed upstream of the point where minimum deflection is required for a TL-3 system, or 40 sections must be deployed upstream of the point where minimum deflection is required for a TL-2 system. Materials The primary elements of the NSS-QMB shall be constructed of ASTM, A-36 steel and high strength concrete. All external steel shall be hot dipped galvanized in accordance

18 TB Rev. 1 Page 2 of 3 with ASTM, A 123. All structural welds shall be continuous. The shell shall be constructed of 0.25 (6.4 mm) A-36 steel. System Requirements The NSS-QMB system, when installed in accordance with the manufacturers instructions, shall function as a longitudinal barrier. Narrow Steel Shelled Variable Length Barriers (NSS-VLBs) shall be added to the length of the NSS-QMB installation in order to allow a smooth lateral transfer through the Barrier Transfer Machine. The number and location of NSS-VLB units that shall be required will vary depending on specifics of the application, number and degree of curves, changes in elevation, etc.
