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.

This Environmental Assessment (EA) has been prepared for the Federal Boulevard Improvements Project. The stretch of Federal Boulevard in the Project Area is lined by commercial development with residential development behind the businesses. Federal Boulevard serves as a high travel-demand traffic corridor. This is a local-agency project sponsored by the City and County of Denver (CCD) in conjunction with CDOT and the Federal Highway Administration (FHWA) serving as joint lead agencies., K'ollorado-ju Tenbŏ-si Tenbŏ-k'aunt'i ; taptang pusŏ Yŏnbang Kosoktoro Kwallich'ŏ K'ollorado-ju Kyot'ong-bu., "2014-yŏn 10-wŏl 1-il.", Includes bibliographical references., Saŏp pŏnho: NHPP 2873-172, Saŏp k'odŭ: 19957, Online resource; title from PDF cover (viewed April 2020)

The goal of this project is to investigate the hydraulic efficiencies of Type 13 (bar inlets), Type 16 (vane inlets), and Type R (curb-opening inlets) for street and roadway drainage. Although these inlets have been widely used in many metropolitan areas, the design empirical formulas and coefficients have not been verified., "April 2012.", "Report No. CDOT-2012-3.", Includes bibliographical references (p. 43-44), Description based on online resource; title from PDF cover (viewed September 2012)
The Colorado Department of Transportation (CDOT) is conducting a PEL study for southbound I-225 between Yosemite Street and Interstate 25 (I-25) in the City and County of Denver, Colorado. CDOT is conducting the I-225 PEL (Yosemite to I-25) to assess existing conditions, identify anticipated problem areas, and develop and evaluate transportation improvements to reduce congestion, improve mobility, and enhance the safety of I-225 within the study area. CDOT, in cooperation with the Federal Highway Administration (FHWA), is preparing this PEL study., prepared for Colorado Department of Transportation, Region 1 ; prepared by Felsburg Holt & Ullevig., "November 2013.", Bibliography pages 77-78., CDOT Project No. STA 2254-085 (19187), FHU Reference No. 112200-01., Online resource; title from PDF title page (viewed July 2016)
