As an alternative to the flat base line , a profiled baseline meeting the following dimensions may be applied. The profiled baseline shall have a minimum height of 0 . 155 inches , when measured above the pavement surface at the edge of the inverted rib profile . The thickness in the bottom of the profile marking shall be 0 . 035 to 0 . 050 inches . The individual profiles shall be located transversely across the full width of the traffic stripe at approximately 1 . 0 inch on center, with a bottom width between 0 . 090 to 0 . 310 inches . Measure, record and certify on a Department approved form and submit to the Engineer, the thickness of white and yellow pavement markings in accordance with FM 5 .541 . 7014 .3 Dimensions of Audible Bumps : Apply the raised bumps with a profile such that the leading and trailing edges are sloped at a sufficient angle to create an audible and vibratory warning . Bumps on shoulder and centerline markings shall have a minimum height of 0 . 45 inches , including the base line . The height shall be measured above the pavement surface at the edge of the marking, after application of drop-on reflective elements . Bumps shall have a minimum dimension of 2 . 5 inches . The bumps may have a drainage channel , the width of each drainage channel will not exceed 1 /4 inch at the bottom of the channel . The longitudinal distance between bumps shall be approximately 30 inches . 7014 .4 Retroreflectivity : Apply white and yellow audible and vibratory markings that will attain an initial retroreflectance of not less than 300 mcd/lx m2 and not less than 250 mcd/lxern respectively. Measure, record and certify on a Department approved form and submit to the Engineer, the retroreflectivity of white and yellow pavement markings in accordance with FM 5 - 541 . jr The Department reserves the right to test the markings within 3 days of receipt of the Contractor' s certification . If the retroreflectivity values measure below values shown above, remove and reapply the striping. 7014 . 5 Color : Use pavement marking materials that meet the requirements of 971 . 1 . 7014 . 6 Reflective Elements : Apply reflective elements to all markings at the rates determined by the manufacturer ' s recommendations as identified for the QPL System . 7014 . 7 Loss : If more than 1 % of the bumps or more than three consecutive bumps are missing or broken (less than half a bump remaining) within the first 45 days under traffic, replace all failed bumps at no expense to the Department. If more than 2 % of the bumps fail within the first 45 days under traffic, the replacement period will extend an additional 45 days from the date all replacement bumps were installed. If, at the end of the additional 45 days , more the 2 % of all bumps (initial and replacement) fail, replace all failed bumps at no expense to the Department . Measure , record and certify on a Department approved form and submit to the Engineer, the loss of bumps . 701 -5 Contractor ' s Responsibility for Notification . Notify the Engineer prior to the placement of audible and vibratory markings . Furnish the Engineer with the manufacturer ' s name and batch numbers of the thermoplastic materials and reflective elements to be used. Ensure that the batch numbers appear on the thermoplastic materials and reflective elements packages . - 192 - FPID (S ) : 423186 - 1 - 58 - 01 , � n r i 'z --;� ..';.. .aa : . ` ;r• a w a' - r s"` - , ;Mx ., ' , i , .r- ks } x .: . . ^r .. - r f " ` ' ?: . s ..
