DYNAMIC TESTS OF STEEL BOX BEAM AND CONCRETE MEDIAN BARRIERS

A STUDY TO DETERMINE THE EFFECTIVENESS OF (1) A STEEL BOX BEAM MEDIAN BARRIER DESIGN DEVELOPED BY THE NEW YORK DEPARTMENT OF PUBLIC WORKS AND (2) A CONCRETE MEDIAN BARRIER DESIGN DEVELOPED BY THE NEW JERSEY HIGHWAY DEPARTMENT, BY MEANS OF FULL-SCALE DYNAMIC IMPACT TESTS IS REPORTED. THREE TESTS WERE CONDUCTED ON THE BASIC NEW YORK 6 X 8 X 1/4-IN. BOX BEAM DESIGN AT SPEEDS OF 71, 64 AND 49 MPH AND APPROACH ANGLES OF 25, 25 AND 7 DEG, RESPECTIVELY, WITH SLIGHT MODIFICATIONS TO THE BEAM-TO-POST CONNECTIONS FOR EACH TEST. THREE TESTS WERE CONDUCTED ON THE 32-IN. HIGH NEW JERSEY CONCRETE BARRIER DESIGN AT SPEEDS OF 38, 65, AND 63 MPH AND APPROACH ANGLES OF 7, 7, AND 25 DEG, RESPECTIVELY. FINDINGS INDICATE THAT BOTH THE BOX BEAM AND THE CONCRETE MEDIAN BARRIER DESIGNS PERFORM EFFECTIVELY AND ARE SUITABLE FOR USE ON FLAT, PAVED MEDIANS FREE OF CURBS, DIKES, DITCHES, AND SAWTOOTH SLOPES. THE MEDIAN WIDTH FOR PLACEMENT OF THE BOX BEAM BARRIER SHOULD BE AT LEAST 10 FT TO PROVIDE FOR LARGE DEFLECTIONS. THE CONCRETE BARRIER APPEARS TO BE RELATIVELY MAINTENANCE FREE AND IS PARTICULARLY SUITABLE FOR PLACEMENT ON NARROW MEDIANS. /AUTHOR/
