Extent of Top-down Cracking in Colorado

Pages : 64
Book Description
In 2000, a forensic evaluation was conducted on a project that was exhibiting early longitudinal cracking near the wheel paths. A team of national asphalt experts conducted this forensic evaluation. The forensic team concluded that the cracking on the project was surface initiated cracking and was caused by a number of contributing factors. One of the contributing factors to the early distress that was identified by the experts were the pockets of segregation that were observed at the bottom of the surface lift but were not apparent on the surface. The object of this study was to determine the extent of "top-down cracking" in Colorado, what causes it, how can it be prevented, if it occurs how is the distress treated, and how quickly does the distress need to be treated.
Performance Evaluation of Various Corrosion Protection Systems of Bridges in Colorado

Book Description
Corrosion of reinforced concrete structures has been a significant problem for many state and transportation agencies since the application of deicing salts was introduced. Much research has been conducted to develop corrosion protection systems that can prolong the life span of reinforced concrete structures. The Colorado Department of Transportation (CDOT) has several routine and experimental measures to prevent corrosion of the rebar including epoxy-coated rebar, calcium nitrite admixture, organic corrosion inhibitors, a thick cover of quality concrete, and a waterproofing membrane covered by an asphalt overlay. An extensive literature review was performed to collect information on various corrosion protection systems that have been used in the U.S. and around the world. Current CDOT practices in terms of corrosion protection measures were reviewed. A draft inspection plan for Colorado's bridge structures was proposed.
