Historic streetcar systems of Colorado
Historic streetcar systems of Colorado
Transportation impacts to historic streetcar lines in Denver and other communities in Colorado are often unforeseen given that many tracks lay underneath paved streets and are not well documented. This results in frequent unanticipated discoveries during construction of publicly assisted transportation improvement projects in Colorado. A historic context was developed to provide a consistent methodology for the evaluation of historic streetcar lines. A corresponding GIS component was developed to provide reliable and consistent mapping of the former streetcar line in Colorado along with pertinent information relative to each streetcar line, including ownership, technical information, dates of operation, and current condition, if known., Nick VanderKwaak, Jennifer Wahlers, Dianna Litvak, Ethan Raath., "September 2020.", "Performing organization: Mead & Hunt, Inc., ARCH Professionals, AECOM.", Includes bibliographical references pages 377-415., Report No. CDOT-2020-11.", Online resource; title from PDF cover (viewed October 2020)

Hot mix asphalt voids acceptance review of QC/QA data 2000 through 2010
This report analyzes the quality control/quality assurance (QC/QA) data for hot mix asphalt (HMA) using voids acceptance as the testing criteria awarded in the years 2000 through 2010. Analysis of the overall performance of the projects is accomplished by reviewing the Calculated Pay Factor Composite (CPFC) and Incentive/Disincentive Payments (I/DP). Analysis of each of the elements: asphalt content, voids in mineral aggregate (VMA), air voids, mat density, and joint density is presented in tables, figures, and reports. Various data groupings are used to evaluate the data including: year, region, and grading. The specification and the projects are performing reasonably well. The results for the data show that quality of the projects is remaining fairly consistent. No definite upward or downward trends can be seen in the data. Over the eleven-year time period more projects have received incentive payments than disincentive payments. The average CPFC over the eleven years evaluation is 1.00569. The quality levels in the individual elements are at relatively high levels. The VMA and mat density elements show the best results being above 93 percent within the specification limits. The asphalt content and air voids elements are at approximately 90 percent. The joint density pay factor is under 1.0 but is expected to rise as contractors gain experience in this area., Final report., "Report No. CDOT-2011-15.
