TRUCK TESTS ON TEXAS CONCRETE MEDIAN BARRIER

THE TEXAS CONCRETE MEDIAN BARRIER, WITH INCLINED SURFACES, SATISFACTORILY RESTRAINED AND REDIRECTED A LARGE 48,800-LB TRACTOR-TRAILER TRAILER TRUCK WITH LOAD UNDER THE FULL-SCALE IMPACT TEST CONDITIONS OF 35 MPH AT A 19-DEG ANGLE, 34 MPH AT A 16-DEG ANGLE, AND 45 MPH AT A 15-DEG ANGLE. THE TRUCK WAS REMOTELY CONTROLLED FROM A CHASE PICKUP VEHICLE. THERE WAS DAMAGE TO THE SHEET METAL OF THE FRONT FENDER AND RUNNING BOARD OF THE TRACTOR. ESTIMATED REPAIR COST WAS LESS THAN $200. MAINTENANCE OF THE BARRIER WOULD REQUIRE, AT MOST, A LIGHT SANDBLASTING JOB TO REMOVE THE UNSIGHTLY TIRE SCRUB MARKINGS. THE SMALL AMOUNT OF CONCRETE SPALLING THAT OCCURRED IN THE IMMEDIATE AREA OF IMPACT WOULD REQUIRE NO MAINTENANCE. THE FENCE AND LIGHT POLE ON TOP OF THE BARRIER WERE NOT DAMAGED. /AUTHOR/
