About this file
This is a technical specification drawing prepared by the Commonwealth of Kentucky Department of Transportation for the design and placement of channelizing devices used in highway work zones. The document provides detailed standards for traffic control equipment including cones, tubular markers, and Type III barricades that contractors must implement during construction and maintenance activities. The drawing specifies precise dimensions, retroreflective sheeting requirements, placement configurations, and positioning guidelines for channelizing devices along roadways. Key specifications include minimum cone heights of 28 inches, tubular marker heights of up to 42 inches or taller with alternating orange and white stripes, and Type III barricades with minimum rail heights of 18 inches. The document identifies two specific bid items: Item #02014 for barricades and Item #03225 for tubular markers, with the understanding that channelizing devices are typically incidental to the "Maintain and Control Traffic" work item.
The drawing establishes mandatory standards for retroreflective sheeting materials, requiring Type IV or higher reflectivity for all channelizing devices used in highway work zones. All devices must comply with the Department of Highways' MASH crash evaluation criteria and feature orange and white retroreflective sheeting with specific stripe widths and configurations. Contractor or supplier identification, including name and phone number in non-reflective letters no more than two inches in height, may be displayed on barricades. The maximum distance between edges of adjacent retroreflective sheeting strips is limited to three inches, and ballast must be kept to a minimum base area necessary to avoid impeding travel lanes. This drawing was submitted on January 17, 2024, and serves as the standard specification document for traffic control device installation on Kentucky Department of Transportation projects.
