Infiltration-induced landslides are common hazards to roads in Colorado. A new methodology that uses recent advances in unsaturated soil mechanics and hydrology was developed and tested. The approach consists of using soil suction and moisture content field information in the prediction of the likelihood of landslide movement. The testing ground was an active landslide on I-70 west of the Eisenhower/Johnson Memorial Tunnels. Results indicate that the unique hydrology of the site is a key component in its stability and considering the whole water basin and not just the failure area is important., Authors: Alexandra Wayllace, Ning Lu, Jonathan Godt., "December 2017.", Includes bibliographic references (pages 36-38), Report No. CDOT-2017-12, Online resource; title from PDF cover (viewed August 2019)

Mount Evans Highway (SH 5) has been severely damaged by permafrost degradation and freeze-thaw processes. We assessed the effects of the current roadway configuration on the permafrost, hydrologic processes, vegetation, and soils of the Summit Lake Park wetland complex. We also reviewed and synthesized available literature to develop design recommendations for mitigating permafrost degradation, thaw-induced subsidence and frost damage, and hydrologic alterations to alpine wetlands. The existing roadway has profoundly altered permafrost conditions, hydrological processes, and wetland plant communities., Jeremy R. Shaw, David J.

The majority of Simple Made Continuous bridges currently in use are constructed with concrete diaphragms. This report presents the results of numerical analysis and laboratory testing of an alternative simple-made-continuous connection scheme that uses steel diaphragms in lieu of concrete diaphragms. A bridge using steel diaphragms was constructed by the Colorado Department of Transportation in 2005 serves as a basis for the research presented herein. Preliminary analysis discovered potential design flaws in the current bridge connection. This bridge should be inspected and retrofitted based on the results of the physical test. Steel diaphragms are a promising alternative for future SMC bridges and the design guidance provided in this report can be used to create better bridge designs., Robert Johnson, Rebecca Atadero., "December 2018.", Performing organization: Department of Civil & Environmental Engineering, Colorado State University., Includes bibliographical references (pages 84-88), Report No. CDOT-2018-21, Online resource; title from PDF cover (viewed September 2019)

Internally cured concrete has been rapidly emerging over the last decade as an effective way to improve the performance of concrete. Internal curing (IC) holds promise for producing concrete with an increased resistance to early-age cracking and enhanced durability. It is a simple and effective way to cure concrete., Wesley A.

Project Bundling is a contract procurement strategy that is being widely used by many State Transportation Agencies. It is claimed that project bundling can reduce project costs and expedite project delivery. To understand the current state of the practice and perception about project bundling among STA representatives as well as how practices and perceptions differ with STA's level of project bundling experience, a survey was conducted. This report presents the detailed findings of the survey, including the benefits and challenges of the bundling method., Yongwei Shan, Saurav Shrestha, Paul Goodrum, Keith Molenaar., "March 2023.", Prepared in cooperation with the US Department of Transportation, Federal Highway Administration., Includes bibliographical references (page 89-90), Online resource; title from PDF cover (viewed November 2023), TPF-5(260) --Project 6 5260.06., Report number CDOT-2023-02.
Traffic noise abatement in mountain corridors can be difficult because traditional roadside barriers may be ineffective due to topography or may not fit the setting. This study examined current best practices from around the world to gather concepts for mitigating traffic noise in mountain corridors in Colorado. A literature review of prospective noise abatement actions found that noise barriers are the most effective direct noise abatement measure, although quieter pavements could have an important supporting role., Dale Tischmak., "July 2013.", Bibliography: pages 46-49., Online resource; title from PDF cover (viewed March 2016), "Prepared in cooperaton with the U.S. Department of Transportation, Federal Highway Administration.", Report no.
