It combined the variables of base preparation, overlay thickness, slab size, and fiber enhancement into a series of test sections over a 7.2-mile length. This report identifies the performance of the overlays in terms of deflection reduction, reduced cracking, and improved bonding between the portland cement concrete (PCC) and asphalt cement concrete (ACC) base layers. The original research project was designed to evaluate the variables over a 5-year period of time. A second project provided the opportunity to test overlay rehabilitation techniques and continue measurement of the original overlay performance for 5 additional years. 530 $a Also available via the Internet. 536 $a Sponsored by the Highway Division, Iowa Dept. of Transportation, Project Development Division, and the Iowa Highway Research Board. $d Iowa DOT project TR-432. 650 0 $a Pavements $z Iowa $x Overlays. 650 0 $a Pavements, Concrete $z Iowa $x Maintenance and repair. 650 0 $a Portland cement. 650 7 $a overlays (pavements). $2 trt 650 7 $a portland cement concrete $2 trt 650 7 $a whitetopping $2 trt 700 1 $a Edgar, L.E. 700 1 $a Anderson, D.R. 710 1 $a Iowa. $b Highway Research Board. 710 1 $a Iowa. $b Dept. of Transportation. 856 40 $u http://www.dot.state.ia.us/materials/research/reports/reports%5Fpdf/hr%5Fand%5Ftr/reports/tr432.pdf 939 $a 5576290 941 $a 3 952 $l IAOX771 $d 20240710100729.0 952 $l USUX851 $d 20160823061342.0 956 $a http://locator.silo.lib.ia.us/search.cgi?index_0=id&term_0=A1009C602B0B11DE9A033608A8D7520A 994 $a 02 $b IOZ 952 $l Z7OX851 $d 20090701080000.0Initiate Another SILO Locator Search
