MASH test 3-11 on the 5-inch cast in place deck barrier anchors

Description: "A full-scale crash test was performed to evaluate the impact performance of a Texas T223 concrete beam and post bridge rail anchored to a 5-nch cast-in-place deck (CIPD). The testing followed the MASH standards for Test Level 3 ( TL-#) longitudinal barriers. The test performed was American Association of State Highways and Transportation Officials (AAHSTO) Manual for Assessing Safety Hardware (MASH) test 3-11, which involves a 2270P (500 lb) pickup truck impacting the critical impact point (CIP) of the barrier at a nominal impact speed and angle of 62 mi/h and 25degress, respectively. This test evaluated the strength of the barrier and its anchorage to the 5-inch CIPD."

Determination of Minimum Height and Lateral Design Load for MASH Test Level 4 Bridge Rails

Description: "This research had the objectives of determining the minimum rail height and lateral design impact load for MASH test level 4 bridge rails. Using parametric finite element analysis and subsequent crash testing, the researchers determined the minimum recommended rail height for MASH TL-4 impact conditions to be 36 inches. Later Design impact for MASH TL-4 test conditions was determined to be 80 kips."
