Several years before the publication of the 1970 Manual on Uniform Traffic Control Divices (MUTD), the Colorado Division of Highways initiated field tests to investigate the relative brightness and durability of yellow and white paint stripes in the beaded and unbeaded condition and to determine the acceptability of partially-beaded centerlines. After the issuance of the 1970 edition of the Manual, the Division sought and received FHWA approval for continued testing as proposed in MUTCD Request No. M-1-71. Approximately 100 miles of Colorado State Highways in different geographical areas were striped with half-beaded center lines by reflectorizing only the first 7.5 feet of the normal 15-foot painted segments. The principal purpose of the experimentation was to determine if this method of reflectorization would adequately satisfy the requirements for nighttime visibility and would prove otherwise acceptable.
