Abstract

Temporary concrete barriers are one of the most common types of roadside hardware found on the nation's highways. However, unresolved issues exist for some installations. These issues include the need for a tie-down system for barrier installations placed on asphalt roadway surfaces and an approach transition between temporary concrete barriers and rigid barriers. The objective of this research was to design a tie-down temporary barrier for use on asphalt road surfaces and then apply that tie-down system to the design of an approach transition from freestanding to rigid barriers. The tie-down and transition systems were to be evaluated according to Test Level 3 safety performance criteria set forth in NCHRP Report No. 350. For the asphalt tie-down system, three steel pins were installed in holes on the front face of the barrier. The new tie-down design was crash tested according to NCHRP Report No. 350 Test Designation 3-11. The test was judged acceptable, barrier deflections were reduced, and all barrier...
