Application of Roller compacted concrete in Colorado's roadways
Application of Roller compacted concrete in Colorado's roadways
Roller Compacted Concrete (RCC) is a no-slump concrete mixture that is transported, placed, and compacted with the same construction equipment as asphalt pavement. After only nine months of service, the RCCs already showed noticeable changes in all of the selected properties tested. More tests and field inspections should be conducted in the future after a longer monitoring period to verify and validate the initial findings observed in the material properties and surface conditions of the RCC pavements., "October 2012.", "Report No. CDOT-2012-11.

Arapahoe Road/I-25 interchange system level feasibility study
Arapahoe Road/I-25 interchange system level feasibility study
This report documents the information required for the I-25 and Arapahoe Road Interchange System Feasibility Study, in compliance with the Colorado Department of Transportation (CDOT) Policy Directive 1601 Interchange Approval Process. This document will be used by CDOT to evaluate the interchange improvements request. Arapahoe Road (SH 88) is located in the southern portion of the Denver Tech Center and serves as a key east-west regional roadway connection. I-25 runs north-south through the study area, extending north through Denver and Fort Collins and south through Colorado Springs. The need for interchange improvements at Arapahoe Road and I-25 has grown substantially since the 1980's., submitted to Colorado Department of Transportation on behalf of Arapahoe County ; in association with City of Centennial [and] Greenwood Village ; submitted by David Evans and Associates, Inc., "June 2008.", Online resource; title from PDF title page (viewed January 2018)

Assessing Gazex avalanche control effectiveness with terrestrial laser scanning
Assessing Gazex avalanche control effectiveness with terrestrial laser scanning
This 2-year project used a ground-based laser scanner to map avalanche path snow depths to support an effectiveness assessment of recently-installed Gazex avalanche control systems in the Loveland Pass (Seven Sisters) and Berthoud Pass (Stanley) highway corridors. Scans were collected during snow-free conditions for a baseline, and then prior to and post-storm event and post control operations, as weather and logistics allowed. Snow depth and snow depth change maps were derived from the laser scans, informing an assessment of specific controlled avalanche events and the general performance of the Gazex exploders in the individual starting zones., Jeffrey S.

Assessment and placement of living snow fences to reduce highway maintenance costs and improve safety (living snow fences) study no: 047-10
Assessment and placement of living snow fences to reduce highway maintenance costs and improve safety (living snow fences) study no: 047-10
Living snow fences (LSF) are designed plantings of trees and/or shrubs and native grasses along highways, roads and ditches that create a vegetative buffer that traps and controls blowing and drifting snow. These strategically placed fences have been shown to be cost effective in reducing highway maintenance associated with blowing and drifting snow conditions., Greg Sundstrom., "May 2015.", Prepared in cooperation with the US Department of Transportation, Federal Highway Administration., Bibliography: pages 19-20., Report No. CDOT-2015-01., Online resource; title from PDF cover (viewed April 2016)
Assessment of CDOT revegetation practices for highway construction sites
Assessment of CDOT revegetation practices for highway construction sites
The revegetation of previously disturbed areas from highway construction activities is a critical component to overall site stormwater management strategy. Poor revegetation actions during and after construction can lead to difficulty in deactivating stormwater construction permits (SCPs). Excessive duration of open permits due to poor revegetation success can result in higher non-project costs for erosion control, revegetation rework and maintenance, and regulatory compliance monitoring higher non-project costs for erosion control, revegetation rework and maintenance, and regulatory compliance monitoring and documentation. Open SCPs can increase the potential for regulatory inspections and fines. Unexpected rework and liability costs can be experienced by CDOT maintenance who is responsible for SCP compliance., Arthur Hirsch, Aaron DeJoia., "February 2015.", Prepared in cooperation with the US Department of Transportation, Federal Highway Administration., Bibliography: page 15., Report No. CDOT-2015-02., Online resource; title from PDF cover (viewed April 2016)
Assessment of Colorado Department of Transportation rest areas for sustainability improvements and highway corridors and facilities for alternative energy source use
Assessment of Colorado Department of Transportation rest areas for sustainability improvements and highway corridors and facilities for alternative energy source use
Cost-effective strategies were developed and identified to CDOT Highway Maintenance Managers to reduce rest area operational costs while conserving finite natural resources. Initial cost analysis indicates that reduced operational costs can be realized by implementing water conservation practices (waterless urinals, water harvesting, irrigation, energy conservation and alternative energy practices, and re-use and recycling of solid waste and landscaping transition toward xeriscape practices)., Title from title page., "March 2011.", "Report No. CDOT-2011-3, Final report."--Cover., "Sponsored by the Colorado Department of Transportation, in cooperation with the US Department of Transportation, Federal Highway Administration.", Includes bibliographical references., Performed by Colorado State University--Pueblo, sponsored by Colorado Department of Transportation--Research, Final report, System requirements: Adobe Acrobat Reader., Mode of access: World Wide Web.
