ACCEPTANCE By working closely with each state s Department of Transportation and toll road authority, Trinity Highway Products sales and marketing teams are available to aid in the product approval and specification process. Once approved, specified and let, we begin the manufacturing process in one of our several highway safety manufacturing facilities. EVALUATION Trinity Highway Products uses several independent test facilities to conduct the crash tests for product approval required by the Federal Highway Administration. Each product must meet the requirements of NCHRP-0. Test results are then presented to the Federal Highway Administration for review and acceptance to use on the National Highway System. Highway safety concerns are increasing around the world. Every year, more countries make a commitment to improve conditions for their driving public. TRINITY HIGHWAY PRODUCTS Trinity Highway Products, LLC, headquartered in Dallas, Texas, is a leading manufacturer of highway guardrail, highway guardrail end treatments, temporary and permanent crash cushions, truck-mounted attenuators and cable barrier systems. Offering a full line of standard and proprietary products, Trinity Highway Products is a recognized innovator of highway safety products. Trinity Highway Products manufactures products that have been tested, approved, and accepted as meeting established federal and state safety guidelines. In fact, all products offered by Trinity Highway Products have been accepted and approved by the Federal Highway Administration as being National Cooperative Highway Research Program Report 0 (NCHRP Report 0) compliant. With all federally funded highway projects, state departments of transportation are required to specify guardrail end treatments, crash cushions and barriers that meet state and federal requirements. Trinity Highway Products innovations that satisfy such requirements include the ET-Plus Guardrail End Treatment, Trinity Attenuating Crash Cushion Family (TRACC Family), Heart Energy Absorbing Reusable Terminal (HEART ) and Cable Safety System (CASS )

6 END TERMINALS USAGE HIGHWAY PERMANENT UNIDIRECTIONAL TRAFFIC BI-DIRECTIONAL TRAFFIC BRIDGES/TUNNELS MUNICIPAL/CITY END TERMINALS Trinity Highway Products manufactures a wide variety of end terminals. Trinity Highway Products guardrail terminal product line includes a wide variety of end treatments, including the ET-Plus, Euro-ET, SRT- 0 family and the WY-BET Box Beam End Treatment. ET-PLUS The ET-Plus is a federally approved, competitively priced, energy-absorbing end treatment. It can be used at the termination of flexible barriers on the shoulder of a roadway or in the median. The ET-Plus is a cable-anchored system utilizing standard guardrail components. EURO-ET The EURO-ET offers specifiers and installers the latest innovation of the world s leading guardrail end treatment. The European version of the ET-Plus meets or exceeds EN 7-4 P4 criteria. It is uniquely configured to meet European highway safety specifications. SRT-0 The Slotted Rail Terminal (SRT-0 ) is a gating, flared end terminal and is available in a 6-Post and 8-Post System. The SRT/ HBA 6-Post System, has steel breakaway posts, 4 wood CRT posts, and is installed in a straight-line flare. The straight-line flare offers a simple layout on new installations. The 6-Post System also has steel breakaway posts that are typically reusable after NCHRP Report 0 criteria impacts. The SRT 8-Post System has tube sleeves/wood posts, 6 wood CRT posts, and installs on a parabolic flare. The parabolic flare has a footprint similar to the previously used BCTs and MELTs, making replacement easier. Strategically located slots in the w-beam rail enhance SRT-0 performance. ET-PLUS WY-BET The Wyoming Box-beam End Terminal (WY-BET ) uses an oversized outer tube that telescopes over the standard box-beam rail element. When impacted, within NCHRP Report 0 criteria, on the traffic face within the length of need, the terminal functions like the box beam guardrail to contain and redirect the impacting vehicle. ET-PLUS Offset: 0 to (0-60 mm) Length: (7.6 m), 7 6 (.4 m) or 0 0 (.4 m) Post Spacing: 6 - (90 mm) Length of need: 6 (.8 m) ET-PLUS WY-BET SRT-0 Offset: 0 to 4 0 (9-0 mm) Length: 7 6 (.4 m) Length of need: 6 (.8 m) from the end of the terminal (at the rd post) Parabolic or straight flare options Tall and narrow extruder head.

EN 7-4 P4 compliants. meter pay length. SRT-0 FAMILY (9 mm-0 mm) offset results in reduced installation costs. Two steel breakaway posts are typically reusable after an impact within NCHRP Report 0 criteria. Improved angle struts allow for easier installation. Fewer posts and a straight layout provide cost savings in construction, making replacement easier. 8 EURO-ET WY-BET

7 POSTS Trinity Highway Products manufactures a full range of highway posts, from the Steel Yielding Terminal Post to the O-Post and Hinged Break-Away Post. Each model provides distinct advantages for highway use. HIGH PERFORMANCE, LOW MAINTENANCE STEEL YIELDING TERMINAL POST (SYTP) The Steel Yielding Terminal Post (SYTP) is an innovative steel post configuration that can be utilized in the ET-Plus family of products. The ET-Plus with SYTP is available in a wide variety of configurations when specifying a 0 0 (.4m) terminal system. The post is made of standard material with special shop-fabricated holes. Upon an impact within NCHRP Report 0 criteria, the post yields allowing the ET-Plus head to flatten the rails and absorb some of the energy of the impacting vehicle. SYTP is NCHRP Report 0 Test Level compliant. Yielding action minimizes roadside debris often found with conventional wood post options. Reduction in parts inventory. Galvanized steel reduces issues with wood posts caused by weather. Recycled steel offers environmentally sound options as compared to chemically treated wood posts.

11 GUARDRAIL RADIUS RAIL INFORMATION W-BEAM POST SYSTEMS Rail sections specified to be installed on curves having a radius of feet (.m) to 0 feet (4.7m) can be curved in our fabricating facilities prior to delivery. Rail can be curved either convex or concave as required. Terms convex or concave refer to the direction curved, outward or inward, relative to the traffic face of the rail. The diagrams & chart provide data for locating posts and curves. For assistance, please contact our Sales Offices.

STEP 4: Measure from the first mark-off point (point B) over to the mid-point of the taut string. This measurement (D) is the Rise. STEP : Mark-off two points along the curved cloth tape: One at 6, or 90 mm (point B) and the second at -6 or 80 mm (point C). STEP : Pull string directly from starting point (point A) to the second mark-off point (point C). STEP : Check the chart to find the Radius (R), given the Rise (D). Example: a Rise of 4 inches (0 mm) would result in a radius of 60 feet (8. m). Note: Follow the steps above for each piece of rail section in the curved run. The arc may not be consistent and each consecutive piece of rail may differ in radius from the previous one.
