determined from the measurements. For example, if the average of the measurements is 65 % of the target retro reflectivity, payment for the stripe will be 65 % of the contract unit price. If the average of the 5 retro reflectivity measurements is 50 % of the target retro reflectivity, or less, the stripe shall be removed and replaced without extra compensation. Any portion of the stripe of the stripe that is determined by the Engineer to be noticeably inconsistent with the overall striping and measures less than 50 % of the target retro reflectivity shall be removed and replaced without extra compensation. Retro reflectivity measurements will be made in accordance with the requirements given in ALDOT-422 with the exception of the sampling frequency. Measurements will be made between 7 and 30 calendar days after the completion of the placement of all stripe.

The removal of traffic markings and legends shall be done in accordance with the requirements given in Section 701.

703.04Method of Measurement

The area of Traffic Control Markings or Legends (Items 703-A, 703-B, 703-H, and 703-I) complete in place and accepted will be the sum of the areas shown on the plans for each marking and legend constructed within the required placement tolerance. The Removal of Traffic Control Markings or Legends (Item 703-C) shall be measured in the same manner as prescribed above except that it shall cover only the area from which the markings were actually removed. The area of Temporary Traffic Control Markings or Legends, (Items 703-D and 703-E) complete in place and accepted, will be the sum of the areas shown on the plans for each marking and legend constructed within the required placement tolerance. No measurement for payment will be made for the removal of temporary markings or legends, the removal of such being classified as incidental to the Items of Temporary Traffic Control Markings and Temporary Traffic Control Legends.

705.03Construction Requirements

Equipment shall include an automatic mixing and metering machine capable of preparing a machine type adhesive meeting the requirements of Article 882.04 and metering the amount of adhesive required to affix each marker to the pavement. The procedure for installing the markers shall be that of the Contractor provided such is within the scope of the installation procedure recommended by the manufacturer of the marker and such is demonstrated to be operable and that the markers are firmly affixed to the surface in such a manner that they will not be displaced under traffic; the entire bottom surface shall be coated with adhesive. The installation of the markers shall be such that the color of the marker housing is compatible with the color of the traffic stripes they are to supplement or replace. Reflective pavement markers shall be placed at the designated location in such a way that the color of the reflected light is in accordance with the plan details or as directed by the Engineer. The portions of the highway surface to which the marker is to be attached shall be free of dirt, curing compound, grease, oil, moisture, loose or unsound pavement or any other material which might affect the attachment of the marker to the pavement, with the area to which the marker is to be affixed prepared by sand blasting immediately prior to placement of the marker. The general locations of the pavement markers will be indicated by the plan details or directed by the Engineer. The Contractor shall provide all engineering services necessary to premark and lay out the markers in accordance with the plan details. The Contractor shall submit to the Engineer for approval three copies of a report of survey which clearly indicates the locations for the various types of markers to be used along with spacing, pattern, etc. specified by the plan details. Said report shall be submitted at least two weeks prior to beginning placement operations. Upon acceptance and approval of the report data the Engineer may waive the two week time period noted above. Note is made of the fact that obtaining approval of the above noted report is considered incidental to the work and no time extension or time delay will be considered due to failure to obtain approval of the report. After placement of any temporary markers, the Contractor shall maintain them, at his expense, in such a manner as to provide good, definite delineation during hours of both daylight and darkness until (1) they are overlaid by a subsequent pavement layer, or (2) they are removed as directed by the plans or the Engineer, or (3) in case of a detour road, until traffic is removed from the detour.

The road may be fully open to public travel during the progress of work under this Section. Hence, when work is to be performed under traffic, the Contractor shall operate his equipment and store his materials and supplies in such a manner as to cause a minimum of inconvenience to the traveling public. Upon completion of the work under this Section any damage to the pavement or other facilities caused by the operation or the Contractor's equipment, shall be repaired by the Contractor as directed without additional cost to the State.
