(University of Kansas Center for Research, Inc., 2011-12)Bridge deck crack surveys were performed on twelve bridges on US-59 to determine the effects of mixture proportions, deck type, and girder types on the crack density of reinforced concrete bridge decks. Of the twelve, eight ... -
Field Experiments for Comparing the Effectiveness of Graphics Displayed in a Portable Changeable Message Sign in Highway Work Zones
(University of Kansas Center for Research, Inc., 2012-01)The traditional message format on a portable changeable message sign (PCMS) is text-based, which has been found to have several limitations in recent studies. The use of graphic-aided messages on PCMSs has many advantages ... -
Corrosion Performance of Prestressing Strands in Contact with Dissimilar Grouts
(University of Kansas Center for Research, Inc., 2012-04)To improve the corrosion protection provided to prestressing strands, anti-bleed grouts are used to fill voids in post-tensioning ducts that result from bleeding and shrinkage of older portland cement grouts. Environmental ... -
Effect of Simulated Cracks on Lap Splice Strength of Reinforcing Bars
(University of Kansas Center for Research, Inc., 2012-06)The effect of preexisting cracks, oriented in the plane of and parallel to the reinforcing steel, on the strength of No. 11-bar lap splices was investigated by testing six beams – three with a splice length of 79 in. and ... -
Rapid Macrocell Tests of 2304 and XM-28 Reinforcing Bars
(University of Kansas Center for Research, Inc., 2012-11)The corrosion resistance of 2304 and XM-28 stainless steel bars, produced by a single mill and supplied by a single supplier, was evaluated using the rapid macrocell test outlined in Annexes A1 and A2 of ASTM A955-12. Bars ... -
Anchorage of High-Strength Reinforcing Bars with Standard Hooks: Initial Tests
(University of Kansas Center for Research, Inc., 2013-01)This report describes the initial tests on the anchorage strength of standard hooked bars in concrete. The goal of the testing is to determine the effects embedment length, side cover, tail cover, quantity of transverse ... -
Rapid Macrocell Tests of 2205 and XM-28 Reinforcing Bars
(University of Kansas Center for Research, Inc., 2013-01)The corrosion resistance of 2205 and XM-28 stainless steel bars from two producers and provided by a single supplier was tested in accordance with Annexes A1 and A2 of ASTM 955-12. Three heats of stainless steel were tested: ... -
Development of a Work Zone Training Program
(University of Kansas Center for Research, Inc., 2009-08)Safety in highway work zones has been a major concern for many decades. Over the years, government agencies and highway industry have developed work zone safety training programs to educate general public, professionals, ... -
Stainless Steel Reinforcement as a Replacement for Epoxy Coasted Steel in Bridge Decks
(University of Kansas Center for Research, Inc., 2013-08)The use of deicing salts in the United States has resulted in the steady deterioration of roadway bridge decks due to the corrosion of reinforcing steel. Since the middle 1970s, the principal corrosion protection techniques ... -
