• Abstract:
  This report, in two volumes, compiles the static, pendulum and full-scale crash test results of alternative small sign support systems for Arizona Department of Transportation (ADOT). The tests were conducted and evaluated in accordance with the recommendations of NCHRP Report 230 and the 1985 AASHTO "Standard Specifications for Structural Supports for Highway Signs, Luminaires and Traffic Signals". Results of this research indicate that three-3 lb/ft or (based on energy based analysis) two-4 lb/ft 80 ksi Marion steel u-post supports and stubs assembled using a 4 inch nested splice (support assembled behind the stub) with 1/2 inch spacers and grade 9 bolts, nuts and washers will meet the evaluation criteria. It also is apparent from the results of this study that a slip-base retrofit for a sign support system with up to three P2 Uni-Strut posts will meet the evaluation criteria. In all cases, tests were conducted in NCHRP Report 230 (2) Classification Sl (STRONG) soil. In cases where installation in a "weak" soil is anticipated, further evaluation is required.
