DEVELOPMENT OF A THREE CABLE GUIDE RAIL SYSTEM AND OTHER GUIDE RAIL TESTS, 1967-68.

IMPACT TEST WERE CARRIED OUT ON GUIDE RAIL SYSTEMS FOR RURAL HIGHWAYS. THE TESTS CONFIRMED THAT AN EFFECTIVE POST AND CABLE SYSTEM COULD BE DEVELOPED AND THAT IT WOULD LIKELY TAKE FORM OF THREE 1/2 IN. STEEL CABLES MOUNTED IN 6 IN. CEDAR POSTS SPACED AT 12 FT. CENTERS. A SPECIAL PROVISION WOULD BE REQUIRED TO FACILITATE CABLE TENSIONING AND ANCHORING. THE MORE COSTLY ALTERNATIVE OF HEAVY OR LIGHT STEEL BEAMS ON SIMILAR POSTS DID NOT PREVENT THE TEST VEHICLES (UNDER THE SAME CONDITIONS OF IMPACT) FROM LEAVING THE ROAD. PRELIMINARY TESTS ON TERMINATING DEVICES OR METHODS FOR STEEL BEAM GUIDERAILS AND ON STRONG BEAM DESIGN OF ALUMINUM MEDIUM BARRIERS, INDICATED THE NEED FOR FURTHER DEVELOPMENT WORK TO ACHIEVE SATISFACTORY SYSTEMS. /CGRA/
