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.

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.

Book Description
This study was approved by the CDOT's Research Implementation Committee as a high priority research with the goal of improving the accuracy of the existing and forecasted traffic loads of CDOT's highway network. The overall scope of this project involved examination of those resources directly related to the current statewide ESAL classification system and the generation of this final report discussing the research and analysis conducted and recommendation of procedures required for CDOT to develop and implement a more site-specific ESAL classification system. In this study Nichols Consulting Engineers (NCE) analyzed all available CDOT permanent and portable weigh-in-motion (WIM) data.

Book Description
NSA is a comprehensive collection of international nuclear science and technology literature for the period 1948 through 1976, pre-dating the prestigious INIS database, which began in 1970. NSA existed as a printed product (Volumes 1-33) initially, created by DOE's predecessor, the U.S. Atomic Energy Commission (AEC). NSA includes citations to scientific and technical reports from the AEC, the U.S. Energy Research and Development Administration and its contractors, plus other agencies and international organizations, universities, and industrial and research organizations. References to books, conference proceedings, papers, patents, dissertations, engineering drawings, and journal articles from worldwide sources are also included. Abstracts and full text are provided if available.

Book Description
The purpose of this project was to document the installation of a post-tensioned concrete masonry sound wall constructed as part of a widening and sound wall project along US 36 near Denver, Colorado. In addition, the wall was instrumented at the time of construction to monitor the loss in prestress in the steel tendons over time due to concrete masonry creep and shrinkage and steel relaxation. Tendon tension was monitored for one year to obtain values for the accumulated losses. Accurate losses in post-tensioned concrete masonry are important for economical design. Currently, there are limited data to support an accurate prediction of prestress loss in concrete masonry.
