Dept. of Transportation and DevelopmentSaber, AzizLouisiana State University (Baton Rouge, La.)US Transportation CollectionSeveral LTRC funded studies haveevaluated fatigue damage from heavytruck loads (GVW 100,000 lb.) onLouisiana Bridges.(1-4) The finalreports for these studiesrecommended a field investigation toverify the theoretical studies. LTRCFinal Report 418 entitled \ue2\u20ac\u153MonitoringSystem to Determine the Impact ofSugarcane Truckloads onNon-Interstate Bridges\ue2\u20ac? contains apartial list of bridges that are subjectto overloaded sugarcane trucks (GVW1000,000 lb.). In this proposedstudy, the researcher will select oneof the bridges listed in LTRC FinalReport 418, design, and install amonitoring system to verify the resultspredicted in the report andrecommend an implementationmeasure
