Description
This report presents the development of ultra-high performance concrete (UHPC) using locally available materials that reduce construction costs compared with commercial products. With the aim of achieving a specified compressive strength of 20 ksi, a UHPC mixture is formulated. The implications of various constituent types are examined with an emphasis on silica compounds (silica fume, silica powder, silica sand, finer silica sand, pyrogenic silica,...

Description
Currently, CDOT has no uniform statewide procedure to size detour drainage structures and permanent hydraulic structures using existing methodologies may result in failures. The main objective of the study is to develop a statewide detour drainage structure design procedure that also considers environmental impacts and mitigation measures.

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....

Description
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,...

In December 2004, a Corridor Development and Management Plan (CDMP) for the Ports to Plains Corridor was completed. While the recommendations for the plan were far reaching and extensive, the need for improved truck parking and rest area deficiencies was given a limited analysis, resulting in generalized recommendations for improvements along the Corridor. The Ports to Plains Steering Committee initiated this study to provide an additional Public/Private...
