B.††††† ContractorDetour Signing.When the Contract Documents provide a pay item for Detour Signing and the plans provide a detour-signing plan, provide, maintain, and subsequently remove all required detour signing and supports according to the detour signing plan.

614.07TrafficMaintained.Where the highway under construction is being used by through traffic, including periods of suspension of the work, furnish and maintain pavement markings, lights, construction signs, barricades, guardrail, sign supports, and such other traffic control devices.Maintain pre-existing roadside safety hardware at an equivalent or better level than existed prior to project implementation. Also, provide law enforcement officers, watchmen, and flaggers as necessary to maintain safe traffic conditions within the work limits as directed by the Engineer.

The Department will furnish and erect regulatory signs and guide signs, unless otherwise shown on the plans, within the work limits on all traffic maintained projects.The Contractoris responsible for maintenance of these signs.The Engineerwill approve the erection and removal of any regulatory signs not shown on the plans.

Keep existing signs and traffic control devices in use within the work limits during the construction period unless otherwise indicated on the plans.If existing signs and other traffic control devices must be relocated or modified as a consequence of the work, provide suitable supports and modify the devices with prior approval of the Engineerand the concurrence of the maintaining agency.Keep existing STOP or YIELD signs functioning at all times.The Contractormay adjust the position of these signs with the Engineerís approval.Relocate existing signs that must be adjusted laterally according to the Ohio Manual.Restore relocated or modified signs to the position and condition that existed before construction as directed by the Engineer.When signs are to be covered, provide an opaque covering that covers the entire message, symbol and all of the sign within the border.Do not use fastenings that damage the sign or reflective face; however, the Contractor may use rivets to attach rigid overlay panels.Do not apply adhesive tapes directly to the face of the sign.

When an existing signal operation must be interrupted for a period of time, provide a traffic control method approved by the Engineer.

Whenever it is necessary to divert the flow of traffic from its normal channel into another channel, clearly mark the channel for such diverted traffic with cones, drums, barricades, vertical panels, pavement markings, or flashing arrow panels.Also use this method of marking where working adjacent to the part of the highway in use by the public.

Obtain the approval of the Engineerbefore closing a traffic lane or establishing a one-way traffic operation.

614.08Flaggers.Whenever one-way traffic is established, use at least two flaggers unless the Engineerauthorizes otherwise, and erect signs, cones, barricades, and other traffic control devices according to the Ohio Manual.Reflectorize traffic control devices as previously noted.Maintain positive and quick means of communication between the flaggers at the opposite ends of the restricted area.

Equip flaggers according to the standards for flagging traffic contained in the Ohio Manual.When a flagging operation, other than an intersection or a spot location best controlled by a single flagger, ensure that each flagger uses a STOP/SLOW paddle conforming to the Ohio Manual.Mount the paddle on top of a 6 1/2-foot (2 m) handle.Ensure that each face of the paddle is made of Type G reflective sheeting meeting the requirements of 730.19.While flagging, do not allow flaggers to perform other work activities.The Contractormay, instead of flaggers, or supplementing them, furnish, install, and operate a traffic signal or signals, for the purpose of regulating traffic according to a written agreement approved by the Engineer.

614.09Law Enforcement Officer.When shown on the plans, furnish for the services of a law enforcement officer and patrol car equipped with flashing lights.

614.10Work Zone TrafficSignals.If shown on the plans, furnish, erect, maintain, and subsequently remove signal equipment conforming to Item 632 and 732, and signal controller equipment of a proper type and capacity to provide the required operation.Subject to the Engineerís approval, the Contractormay use new equipment that is to be installed later on the project, or may install used equipment in good condition provided such used equipment meets current Department specifications.The performance test in 632.28 and the working drawing requirements of 632.04 are waived.Recondition used equipment as necessary to ensure proper operation.Operate work zone traffic signals conforming to the requirements of the Ohio Manual and subject to the approval of the Engineer.

Procure and pay for electric power for work zone traffic signals.Do not alter the operation of an approved work zone traffic signal without the Engineerís approval.Correct any malfunctions or failures without delay.Cover or remove work zone traffic signals not in use.

Ensure that Type I and II preformed material conform to 740.06, except do not place any preformed material containing metal on any surface unless it will be removed later.Remove work zone pavement markings of 740.06 preformed material before placement of 642 or 644 surface course markings at that location.Ensure that preformed material conforms to Item 645, except as modified in this specification.

C.††††† Work Sequence.Ensure that work zone markings are complete and in place on all pavement, including ramps, before exposing the pavement to traffic.When work zone markings conflict with the traffic pattern, remove them according to 641.10.

D.††††† Tolerances.Place lines for final surfaces according to the tolerances of 641.07.On surfaces other than final, the Department will allow tolerances twice that in 641.07.Perform layout and premarking according to 641.06.

E.††††† Marking Dimensions.

1.††††† Class I Markings (Full Pattern).Apply Class I work zone markings to the standard dimensions as defined in Item 641 with the following exceptions:make transverse and crosswalk lines 8 inches (200 mm) wide, and make stop lines 12 inches (300 mm) wide.

2.††††† Class II Markings (Abbreviated).Class II work zone markings are defined as follows:

a.††††† Center Lines.Class II center lines consist of single, yellow 4-inch (100 mm) wide by a minimum of 4 feet (1.2 m) long dashes spaced at a maximum of 40 feet (12.0 m) intervals.

b.††††† Lane Lines.Class II lane lines consist of white 4-inch (100 mm) wide by a minimum of 4 feet (1.2 m) long dashes spaced at a maximum of 40 feet (12.0 m) intervals.

c.††††† Gore Markings.Class II gore markings are continuous, white 4-inch (100 mm) wide lines placed at the theoretical gore of an exit ramp or diverging roadways.

F.††††† Conflicting Markings.Before placing work zone markings, remove or cover all conflicting existing markings visible to the traveling public.

1.††††† Removal and Covering of Markers.

a.††††† Removal Methods.Remove the markings by using small handheld grinders or scarifiers, sandbasting, or other methods approved by the Engineer.Exercise care during marking removal not to scar, discolor or otherwise damage the pavement surface.

b.††††† Covering Conflicting Markings.Do not cover, remove, or obliterate existing markings by overlaying them with black paint or asphalt; however, with the Engineerís approval, use removable, nonreflective, preformed tape that minimizes contrast with the pavement where markings need to be covered temporarily.

2.††††† Raised PavementMarkers.Remove the prismatic retro-reflector within any raised pavement marker that is in conflict with the work zone pavement markings.When the work zone pavement markings are removed and the raised pavement marker is no longer in conflict, thoroughly clean the recessed reflector attachment area of the casting and install a new prismatic retro-reflector of the same kind and color.The cost for this work is incidental to the various pay items.

G.††††† Allowable Duration of Work Zone Markings.

1.††††† No Passing Zones. When existing permanent no-passing-zone markings are removed or obliterated as the result of a construction operation (pavement grinding, asphalt concrete pavement overlays, etc.) and the section of pavement continues to be used by the traveling public, place final center line markings as specified by the plan within 3 Calendar Days.The Contractormay use equivalent 614 Class I center line markings instead of final markings.

a.††††† Subsequent Work in No Passing Zones.If, after the original markings are removed or obliterated, the Contractorreturns to the subject no passing zone and places a plan-specified pavement course within the 3-Calendar Day limit, or performs work in preparation for a subsequent pavement course, the Contractor shall have temporarily satisfied the conditions of the previous paragraph.In this event, the 3-Calendar Day limit will begin again.

b.††††† Liquidated Damages. For each Calendar Day beyond 3 days that this work remains incomplete, the Department will assess liquidated damages in the amount of $1000 per Calendar Day.The Department will treat the time for the completion of no-passing-zone markings as an interim Completion Date.

2.††††† Passing Zones.Conform to the 14-day limit described below for sections of pavement where passing is permitted in both directions.

3.††††† Allowable Duration of Class II Lane Lines and Gore Markings and Absence of Edge lines.Any time existing permanent lane lines, gore markings, or edge lines have been removed or obliterated as the result of a construction operation (pavement grinding, asphalt pavement overlays, pavement widening, etc.) and the section of pavement continues to be used by the traveling public, place final pavement markings as specified by the plan within 14 Calendar Days.The Contractormay use equivalent 614 Class I markings instead of final markings.

a.††††† Subsequent Work.If, after the original markings are removed or obliterated, the Contractorreturns to the subject section of pavement and places a plan-specified pavement course within the 14-Calendar Day limit, or performs specified work that requires a lane closure (except routine maintenance required by 614.02), the Contractor shall have temporarily satisfied the conditions of the previous paragraph.In this event, the 14-Calendar Day limit will begin again.

b.††††† Liquidated Damages.For each Calendar Day beyond 14 days that this work remains incomplete, the Department will assess liquidated damages in the amount of $1000 per Calendar Day.The Department will treat time for the completion of these markings as an interim Completion Date.

(1)†††† Continuous Project.If a section of pavement is in a continuous part of the project, then a new 14-day limit for renewed work on a section applies to all sections in that part.

(2)†††† Project in Sections.If the project is in parts and the traveling public could not discern the parts as one continuous project, then a new 14-day limit in one part will not apply to the other parts.

(3)†††† Freeways and Divided Highways.Treat the two directional sides of a freeway as separate parts.Work on one side of a freeway does not create a new 14-day limit for the other side.

614.115†† Work Zone Raised PavementMarkers.††† Furnish, install, maintain and subsequently remove work zone raised pavement markers (WZRPMs). Work zone raised pavement markers may serve as a substitute for, or supplement to, work zone pavement markings. They are provided in both yellow and white versions to match the appropriate pavement marking color.

White units provide reflectorization in one direction while yellow units may provide reflectorization in either one direction or two They are available as units which are readily visible both night and day as a result of retroreflectors and brightly colored (white or yellow) housing (Type A) or visible only at night due to their retroreflectors (Type B).

A.Materials. Prequalify work zone raised pavement markers according to Supplement 1056.

Only use adhesives that are recommended by the reflector manufacturer and are not epoxy.

Provide markers of sufficient strength and properly shaped so as not to be dislodged or broken by impacts from vehicle tires, including those of high pressure truck tires loaded to 4500 pounds (2040 kilograms).

Provide reflectors having an area of 0.35 square inches (225 square millimeters) for Type A or 3.0 square inches (1935 square millimeters) for Type B.The brightness or specific intensity (when tested at 0.2 degree angle of observation and the following angles of incidence) meet or exceed the following:

C.Installation. Attach work zone raised pavement markers to clean dry and sound pavement. Remove all loose gravel, sand and dirt from the area of the line. The minimum pavement temperature for installation is 50 degrees F (10 degrees C). When markers are attached to new concrete pavement with curing compound remaining, remove the curing compound membrane by sandblasting or other mechanical cleaning method. Install markers in accordance with the manufacturer's recommendations.

Work zone raised pavement markers are not suitable for use from October 15 to April 1.If the Contractorelects to start or continue work zone pavement markers during this period, and they fail or are subsequently removed or destroyed by snow and ice control activities, immediately, at his expense, provide a substitute traffic guidance system which is effective during day and night and which is acceptable to the Engineer.Other than for replacement of failed WZRPMs, new installations of WZRPMs are not permitted from October 1 to April 1.

Place markers accurately to depict straight or uniformly curving lines. The longitudinal location of WZRPMs are described in Table I except that the spacing of an individual WZRPM may be varied by as much as 2 feet (0.6 m) or 10 percent of the nominal spacing in order to avoid poor pavement conditions, but the average spacingremains unchanged. Poor pavement conditions include separated joints, cracks, deteriorated pavement, usually uneven pavement or where pavement marking material will interfere with the bond.

The lateral location of WZRPMs follows:

††††††††† 1.†††††† Edge Lines:Offset 12 inches (300 mm) outside the work zone pavement marking, if any, or the theoretical edge of the lane, but this offset may vary+6 inches (150 mm) as necessary to avoid poor pavement conditions.

††††††††† 2.†††††† Lane linesand dashed center lines: Locate the WZRPM in the center of the gap between pavement marking dashes, if any. If a pavement joint exists, provide the marker with 2 inches (50 mm) clear distance from it (and to the left of it for lane lines). Otherwise, center the WZRPM on the theoretical edge of lane.

††††††††† 3.†††††† Double center line: Install each WZRPM of the pair in line with the appropriate pavement marking stripe, if any. If the edge of lane is demarcated by a crack or joint, the pair of WZRPMs straddle the joint and each is installed approximately 2 inches (50 mm) clear from the joint. Otherwise center the pair on the theoretical edge of lane.

††††††††† 4.†††††† Channelizing Line: In line with the pavement marking stripe or immediately adjacent to the line, except when used at exit gore outlines where the WZRPM is installed within the painted gore vee and approximately 12 inches (300 mm) from the pavement marking stripe. WZRPMs will not be placed directly on a painted line.

D.†† Replacement.†† Maintain WZRPMs in good condition. Markers have failed when: the marker is broken, the marker is worn to the extent that daytime visibility is significantly diminished or of an unacceptable color (type B only), reflectors are broken or detached, markers are detached from the adhesive, the adhesive is detached from the pavement or if markers or reflectors are covered by tar or paint.

Individual replacement of each failed marker as it occurs is not recommended due to increased exposure of workers to traffic. However, maintain the following minimum levels of marker effectiveness:

††††††††† 1.†††††† For a given line, no more than 20 percent of the WZRPM units failed in any manner;

††††††††† 2.†††††† For a segment of any line, the number of failed units do not exceed the maximums permitted in Table 614.115-2.

Replace all failed units within any line or segment before conditions deteriorate below the minimums established in Table 614.115-2. Replace all failed units within the line or segment within 24 hours after notification by the Engineer.

E.†† Removal. Accomplish removal of work zone raised pavement markers in such a manner that no adhesive remains on the pavement. Permanent pavement surfaces are not to be scarred, broken or significantly roughened.

614.12PavementMarking Operations.Perform moving marking operations with a truck equipped with necessary flashers and signs, and protect the operations with a similarly equipped vehicle or vehicles separated a sufficient distance to provide adequate advance warning.Use the extreme left or right lane for the marking operation when possible.Where three or more lanes exist in one direction, perform the marking operation so that traffic passes on one side only.

Protect stationary marking operations in intersections, school zones, gores and other areas with traffic control devices such as advance warning signs and cones.

For stationary operations such as loading material and cleaning equipment, make every effort to have all equipment completely off the traveled way.When equipment cannot be removed from the traveled way, operate all traffic control devices on the vehicles and station flaggers and vehicles to protect the worksite and the traveling public while maintaining two-way traffic.

614.13AsphaltConcretefor Maintaining Traffic.The Contractormay use either a Type 1 or Type 2 mix of Item 448 asphalt concrete PG 64-22, or an asphalt concrete surface course the Engineerapproves.Place surface course materials as and where the Engineer directs for maintenance of the existing pavement, shoulders, or structures.

Where materials are placed in small quantities or under adverse conditions, the Engineermay waive specification requirements for placing and finishing if, in the judgment of the Engineer, it is determined that the Contractorcan obtain satisfactory results in providing a smooth and durable pavement surface.

614.14Performance.If, in the opinion of the Engineer, the Contractoris not furnishing proper maintenance of traffic facilities and proper provisions for traffic control, the Department may take the necessary steps to place them in proper condition, and the Department will deduct the cost of such services from any money that may be due or become due the Contractor.

614.15Method of Measurement.The Department will measure Work Zone Marking Signs as the number of sign installations, including the sign, necessary supports, and all attachment hardware.The Department will include all other work zone signs under Maintaining Trafficunless separately itemized.
