Numerous projects have been constructed and tested, allowing researchers to identify the important elements contributing to the projects' successes. These elements include surface preparation, overlay thickness, synthetic fiber reinforcement usage, joint spacing, and joint sealing. Although the main factors affecting thin whitetopping performance have been identified by previous research, questions still existed as to the optimum design incorporating these variables. The objective of this research is to investigate the interaction between these variables over time. Laboratory testing and field testing were conducted to achieve the research objectives. Laboratory testing involved shear testing of the bond between the Portland cement concrete (PCC) overlay and the ACC surface. Field testing involved falling weight deflectometer deflection responses, measurement of joint faulting and joint opening, and visual distress surveys on the 9.6 mile project. The project was located on Iowa Highway 13 extending north from the city of Manchester, Iowa to Iowa Highway 3 in Delaware County. Variables investigated include ACC surface preparation, PCC thickness, slab size, synthetic fiber reinforcement usage, and joint spacing. This report documents the planning, construction, and performance of each variable in the time period from summer 2002 through spring 2006. The project has performed well with only minor distress identification since its construction. 530 $a Also available via the Internet. 536 $a Sponsored by the U.S. Federal Highway Administration, Iowa Highway Research Board, and Iowa Dept. of Transportation $d CTRE project 01-95. $d HR-1093 $d IHRB project TR-478 $d CTRE project 01-95. 650 0 $a Pavements $x Testing. $x Testing. 650 0 $a Pavements, Composite $x Testing. 650 0 $a Pavements, Asphalt $x Testing. $9 27073 650 7 $a whitetopping. $2 trt 650 7 $a asphalt pavements. $2 trt 650 7 $a overlays (pavements). $2 trt 650 7 $a falling weight deflectometers. $2 trt 700 1 $a Morud, Jennifer L. 700 1 $a Tabbert, Toni R. 710 1 $a Iowa. $b Department of Transportation. 710 1 $a Iowa. $b Highway Research Board. 710 1 $a United States. $b Federal Highway Administration. 710 2 $a Iowa State University. $b Center for Transportation Research and Education. 856 40 $u http://www.operationsresearch.dot.state.ia.us/reports/reports%5Fpdf/hr%5Fand%5Ftr/reports/tr478.pdf 941 $a 3 952 $l IAOX771 $d 20240710101017.0 952 $l OVUX522 $d 20180103024701.0 952 $l USUX851 $d 20160823082044.0 956 $a http://locator.silo.lib.ia.us/search.cgi?index_0=id&term_0=B5EFF89C493111E49277FB87DAD10320 994 $a C0 $b IOZInitiate Another SILO Locator Search
