701.03 Construction Requirements.
Hiding the old stripe by covering it with a striping material that is colored to match the appearance of the pavement surface will only be allowed if approved in writing by the Engineer. Covering the old stripe will only be considered for hiding what may remain of the stripe on rough pavement surfaces like Open Graded Friction Course after other methods of removal have failed to adequately remove the old stripe. The Contractor shall propo se the type, color and application rate the striping material for review and approval by the Engineer. There will be no extra compensation given for furnishing and applying striping material to hide an existing stripe.

1.Permanent Striping . A tolerance of 1/2 of an inch {13 mm} over or 1/8 of an inch {3 mm} under the required width will be allowed, provided the variation is gradual and does not detract from the general appearance. Segments of broken line may vary up to 1 foot {0.3 m} from the required length. Segments shall have neat edges without mist or drip. Variations fro m the control guide up to 1 inch {25 mm} will be allowed provided the variation does not increase or decrease at a rate of more than 1/2 of an inch {13 mm} in 20 feet {7.5 m}. Lines that do not meet these tolerances shall be removed and replaced, without additional compensation. Establishment of tolerances does not relieve the Contractor of responsibility to construct as closely as practicable to exact plan dimensions.
2.Temporary Stripe. The width of the temporary stripe shall not exceed 4 inches {100 mm }, but shall have a 1/2 inch {13 mm} under tolerance. Traffic marking tape shall have a nominal 4 inch {100 mm} width. The tolerance for the lengths of the temporary broken stripe sections shall be 1 foot {0.3 m} under and 1 foot {0.3 m} over the length sp ecified in Subitem 701.03(e)5.a. Strict compliance to alignment on underlying surfaces will not be required provided a reasonable straight line of markings is obtained. The tolerances for placement on a wearing surface shall be the same as those for perman ent striping.
3.Failure to Meet Width and Length Placement Tolerances . Permanent or temporary striping placed on a final wearing surface that does not meet the tolerances specified shall be removed and replaced without compensation. This includes areas where the permanent striping does not match the alignment, spacing, etc. of the temporary stripe, leaving the temporary stripe exposed. Portions, or as much as the entire pavement surface, shall be overlaid with a bituminous plant mix layer in extreme cases of disfigurement of the pavement due to stripe removal. The Engineer will make the final determination of the severity of the disfigurement, the requirement for the extent of the overlay, and the material and placement requirements for the plant mix requ ired for the overlay. The Contractor shall place the overlay without compensation.
l.Protection Of Traffic Stripe . Traffic shall be prevented from crossing traffic stripe that is not dried, cured or taken a set to bear the traffic. The Contractor shall use a sufficient number of flagmen or other protection for the stripe to prevent traffic from damaging the newly applied stripe. Sections of traffic stripe that have been marred or picked up by traffic shall be repaired and the pavement shall be cleaned outside the limits of the stripe. Repair and cleaning shall be done by the Contractor without extra compensation.
m.Protection Of Traffic . The Contractor shall furnish and place without extra compensation all warning and directional signs required to direct, control and protect the traveling public while marking and striping operations are in progress. Temporary barricades and signs of the design shown on the plans or directed by the Engineer shall be placed as shown on the plans at the beginning and end of the section that the Contractor proposes to stripe in one operation. As soon as the striping material has dried or cured
701.04 Method of Measure ment.
sufficiently in any one section to permit traffic to cross the traffic line, the temporary barricades and signs shall be moved ahead to the next section. Barricades and signs shall not be left in place overnight. The striping equipment shall be operated in a manner to cause the least disruption to the normal flow of traffic.
