This study determined the feasibility of using driven piles to stabilize highway embankment slopes. The activities performed under this study were a detailed literature review, a national survey of state DOTs, a review of inspection and stabilization mitigation reports, targeted field inspections, a cost comparison analysis, and a finite element study. The results of this study show that driven piles can be a cost-effective solution to stabilizing highway embankment slopes., "Sponsored by the Colorado Department of Transportation in cooperation with the U.S. Department of Transportation, Federal Highway Administration.", "December 2010.", "Report No. CDOT-2010-8, final report."--Cover, Includes bibliographical references (p. 35-36, B-10-B-11), Mode of access: World Wide Web.
The Colorado Department of Transportation (CDOT) has been collecting data from the Hamburg Rutter and the French Rutter for over 20 years. No specifications have been written in that time for either the Hamburg Rutter or the French Rutter. This is largely due to the need for a companion test to be developed so dry asphalt mixes would not be designed specifically for passing the Hamburg Rutter test. This report looks at the state of practice within other states that own similar equipment. Cracking tests that could be run with the Hamburg Rutter are examined from a review of literature to determine if there is a suitable companion test for the Hamburg Rutter that would work to keep asphalt levels in the mix high enough to prevent cracking and fatigue., Kim Gilbert, "Prepared in cooperation with the US Department of Transportation, Federal Highway Administration.", "November 2013.", Bibliography: pages 28-29., Report No. CDOT-2013-5, Final Report., Online resource; title from PDF cover (viewed March 2016)

The U.S. Geological Survey (USGS), in cooperation with the Colorado Department of Transportation, determined the peak discharge, annual exceedance probability (flood frequency), and peak stage of two floods that took place on Big Cottonwood Creek at U.S. Highway 50 near Coaldale, Colorado on August 23, 2016, and on Fountain Creek below U.S. Highway 24 in Colorado Springs, Colorado on August 29, 2016., Michael S.

The purpose of this plan is to identify visual intrusions or adverse visual elements within the Colorado Department of Transportation right-of-way along the Peak to Peak Scenic and Historic Byway. The plan's intent is to improve the scenic quality of the Peak to Peak Scenic and Historic Byway noticeably and to enhance the viewer's experience., prepared for Tourism and Recreation Program, Nederland, Colorado ; prepared by Steven P.

As recently as 1969 about half the school aged children in the United States walked or bicycled to school. Today fewer than 15% of school children walk or bike to school and as much as 20-30% of morning traffic is generated by parents driving their children to school. Children are less active today and the majority of children living within a 1/2 mile of schools are driven in private vehicles. Obesity rates are on the rise and the cost of obesity and other health related challenges have significant impacts on the rising cost of health care in the Unites States, not to mention the lifestyles of our children. In response to these challenges, in an effort to encourage healthy living, the Colorado Department of Transportation has developed a series of pedestrian and bicycle safety lesson plans in support of the Colorado Safe Routes to School program. These lesson plans, which help educators teach children about safe walking and bicycling, introduce a variety of skills that can help children stay safe while they walk by teaching them skills that will help them safely cross the street. Statistics show that child pedestrians are disproportionately represented in injury crashes and that the typical factors in those crashes that can be mitigated by education and practice., Online resource; title from PDF cover (viewed November 2016)

The replacement of the CDOT Region 1 Twin Bridge over Smith Road and Union Pacific Rail Road (UPRR) on I-70 provided an excellent opportunity for the performance evaluation of GRS (geosynthetically reinforced soils) abutment. The performance of the GRS abutment was measured using SAA (shape accel array) for lateral deformation and vertical settlement measurement, Geokon 4810 for horizontal earth pressure, 4800 for vertical earth pressure, 4420 for separation measurement between abutment and top of sheet pile wall, 4150 for strain of anchor rod, and optic fiber for geosynthetic strain measurement., Nien-Yin Chang, Hien Manh Nghiem, and Kevin Lee., "March 2020.", "Performing organization: University of Colorado, Department of Civil Engineering.", Report No. CDOT-2020-07.", Online resource; title from PDF cover (viewed September 2020)
Chip seals are used extensively by CDOT for extending pavement life. Chip seals utilizing locally available and minimally processed aggregates should be a more economical pavement preservation treatment than chip seals constructed with higher quality, more expensive aggregates. Low traffic roadways may not demand such materials to perform acceptably. After four winters and three summers service both experimental chip seals are performing well. It appears that locally available, minimally processed aggregates can be successfully applied as chip seal aggregate on low volume roadways., Scott Shuler., "Prepared in cooperation with the US Department of Transportation, Federal Highway Administration.", "July 2013.", Bibliography: pages 72-82., Report No. CDOT-2013-7., Final Report., Online resource; title from PDF cover (viewed March 2016)

This study is the evaluation of two thin bonded epoxy overlays. These two products were compared on the basis of physical properties, including mean texture depth, surface friction, bond strength, ability to stop chloride intrusion, and anti-icing properties, as well as traffic safety and cost. Both overlays worked as intended when they were initially applied on the bridge decks. Mean texture depth and friction testing have shown that they both provide a durable wearing surface with good traction., submitted by Logan Michael Young, Stephan Durham, Rui Liu ; submitted to Colorado Department of Transportation, Applied Research and Innovation Branch., "Prepared in cooperation with the U.S. Department of Transportation, Federal Highway Administration."--Technical report documentation page., "June 2014.", Includes bibliographical references (pages 250-254)., Report No. CDOT-2014-2., Final report., Online resource; title from PDF title page (viewed April 2016)
