This research is being conducted to evaluate the performance of various preventive maintenance treatments over time and under different environmental conditions to assess the economics of each treatment type., "May 2006.", "Report No. CDOT-DTD-R-2006-6.", "Sponsored by Colorado Department of Transportation in cooperation with the US Department of Transportation, Federal Highway Administration.", Includes bibliographical references (p. 74-76)., Mode of access: World Wide Web.
In 2006, CDOT initiated development of a specification for aggregates used in truck arrester beds. First, it was necessary to know what was currently in the arrester beds throughout the state. Each bed needed to be evaluated for safety, performance, and maintenance needs., January 2008., "Report No. CDOT-2008-1, Final Report.", Mode of access: World Wide Web.

This report provides a summary of the roadway characteristics, multimodal facilities, and traffic and safety conditions; identifies infrastructure deficiencies; and summarizes important existing environmental resources in the U.S. Highway 34 (US 34) Planning and Environmental Linkages (PEL) Study Area. This information will be used to determine if obtaining additional data is required, to assess improvement needs, and to guide the development of corridor alternatives. The existing conditions presented in this report represent a snapshot in time current to September 15, 2017, and will be used to determine additional data collection needs for the PEL., prepared for Colorado Department of Transportation ; by CH2M HILL, Inc., "March 2018.", Online resource; title from PDF cover (viewed June 2018), Final.

The Colorado-specific safety knowledge base, developed and effectively applied in the design process at CDOT, is not yet used to inform the planning process. This report transfers the use of these Colorado-specific, predictive and diagnostic tools to the transportation planning process. It develops a proposed methodology for the Explicit Consideration of Safety in the Transportation Planning Process by focusing on science-based and data-driven project selection, which considers susceptibility to cost-effective correction, rather than simply observed frequency and severity of crashes. This methodology will aid in ranking and prioritizing safety aspects of projects in concert with other attributes, such as mobility, air quality, noise, etc. It effectively translates state-of-the-art safety analysis techniques into an applied, practical methodology that transportation planners and practicing engineers can use., Jake Kononov, Richard G.

Express Lanes increase roadway capacity and help manage congestion on Colorado highways by adding lanes that provide a choice to drivers. Motorists can choose to ride the bus, carpool or pay a toll to use the express lanes as an alternative to the free general purpose lanes., video file MPEG 48MB, Produced by Colorado Department of Transportation, Online resource; title from title screen (viewed August 2019)

Roadside vegetation is exposed to a variety of biotic and abiotic stresses that can impact plant health. Drought, pollution, disease, insects, lack of nutrients, and roadbed management practices may potentially act alone or synergistically to adversely af

Colorado Department of Transportation (CDOT) does not have evidence how the Dynamic Cone Penetrometer (DCP) test results correlate to other test methods (say, R-value) for Colorado's pavement subgrade. Even, the correlation between single-mass, and dual-mass DCP (which are two ways of conducting DCP test) is still unknown. Pavement Mechanistic Empirical Design (PMED) guide provides some correlations among different subgrade tests. However, those correlation are derived from national data. Research was thus needed to investigate the correlation between single-mass, and dual-mass DCP, and determine correlations among other subgrade tests for Colorado's pavement soils., Md Rashadul Islam and Sylvester A.

The objective of this study is to determine if the development of a standardized subset of bridge plans s feasible and cost effective. The past 30 years of successful Colorado Department of Transportation bridge design can be used as a starting point to create a standardized subset of bridge plans., Michael McMullen, Chengyu Li., "September 2015.", Prepared in cooperation with the US Department of Transportation, Federal Highway Administration., Cover carries incorrect report number of CDOT-2015-05.
