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.
703.04 Method 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.
