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 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)
