703SHORT TERM AND TEMPORARY PAVEMENT MARKINGS

Art. 703.01 Short Term and Temporary Pavement Markings 624

703.01Description. This work shall consist of furnishing, installing,

maintaining, and removing short term and temporary pavement markings.

703.02Materials. Materials shall be according to the following

Item Article/Section

CONSTRUCTION REQUIREMENTS

703.03General. Short term pavement markings shall consist of abbreviated

patterns for edge, lane, and center line markings. Within a specified time limit, short term pavement markings shall either be resurfaced or removed and replaced with the full pavement marking patterns indicated on the plans with either a temporary material paid for as temporary pavement marking or with permanent material. Within the conditions as specified, the Contractor may be required to place all or a part of the quantities shown on the plans for short term pavement markings and temporary pavement markings.

Before applying the pavement marking material, the pavement shall be cleaned according to the manufacturer. Paint pavement markings shall be installed according to Section 780, except hand-operated stripers may be used for all applications of short term and temporary pavement markings. Epoxy, polyurea, and modified urethane pavement markings shall be installed according to Section 780. Pavement marking tapes shall be applied to the prepared surface according to the manufacturer's recommendations or by a method approved by the Engineer.

703.04Short Term Pavement Markings. Before the lane is opened to traffic,

appropriate short term pavement markings shall be installed between all lanes open to traffic. Center line or lane line markings shall consist of an abbreviated pattern of single stripes 4 ft (1.2 m) in length and a minimum of 4 in. (100 mm) wide at a maximum spacing of 40 ft (12 m) between stripes. Center lines on two-lane highways shall be yellow and lane lines separating two or more lanes of traffic moving in the same direction shall be white. Edge line markings shall be applied on multilane divided highways and other highways with a paved shoulder greater than 4 ft (1.2 m) wide. Edge line markings shall consist of stripes 4 ft (1.2 m) in length and a minimum of 4 in. (100 mm) wide at intervals of 50 ft (15 m) on ramps and 200 ft (60 m) on mainline installed at approximately a 45 degree diagonal pointing in the direction of traffic. Short term pavement markings on the final wearing surface shall be transversely offset from the permanent pavement marking location as directed by the Engineer. Short term pavement markings shall be removed within five calendar days after permanent pavement markings are installed.

Short Term and Temporary Pavement Markings Art. 703.05 625 The short term pavement markings shall be removed and replaced with the required full standard pavement markings consisting of either temporary or permanent pavement marking as soon as possible. Except as indicated below, temporary pavement marking or the permanent pavement markings shall be installed for no passing zones within three calendar days and for all other markings within 14 calendar days, respectively, after the completion of an intermediate or final surface treatment. This time restriction shall begin at the completion of each intermediate or final lift on resurfacing projects.

If the existing markings are obliterated by milling or any other surface treatment, the time restriction shall begin when the entire surface has been treated. These time restrictions may be delayed by the Engineer whenever the Contractor cannot apply pavement markings due to unanticipated inclement weather (other than winter shutdown on the project), strike activities, or other circumstances beyond the Contractor's control as determined by the Engineer. In these cases, the required full standard temporary or permanent markings shall be installed as soon as construction activities are resumed. Prior to winter shutdown, standard edge lines, lane lines, center lines, no passing zones, and any other necessary markings as determined by the Engineer shall be installed on any intermediate or final surface remaining open to traffic during the winter shutdown period.

703.05Temporary Pavement Marking. When an intermediate course

cannot be overlaid or if the final surface cannot be permanently marked within the time restrictions listed above, the full standard markings shall be installed with temporary pavement markings. The temporary markings shall be of the same color and dimensions as shown on the plans for the permanent markings, or as directed by the Engineer.

For late season applications where tape adhesion is a problem, paint, epoxy, polyurea, and modified urethane pavement markings shall not be applied to the final wearing surface unless authorized by the Engineer.

Except during winter shutdown periods, temporary pavement marking showing deterioration for any reason within seven days after placement, shall be replaced by the Contractor. Temporary pavement markings which are in conflict with subsequently established pavement markings, or which interfere with the permanent pavement markings, shall be removed. Temporary pavement markings placed on the final wearing course shall be transversely offset from the permanent pavement markings planned location as directed by the Engineer. Temporary pavement markings shall be removed within five calendar days after permanent pavement markings are installed. When edge lines or channelizing lines are required, they shall be continuous. When continuous sections of tape are used, they shall be cut completely through at intervals of approximately 25 ft (8 m).

Instead of temporary pavement markings, no passing zones on two-lane and three-lane roads may be identified by either the pennant “NO PASSING ZONE” (W14-3) warning sign or both the “DO NOT PASS” (R4-1) and “PASS WITH CARE” (R4-2) regulatory signs in conjunction with short term markings for periods of time up to three calendar days after an intermediate or final lift is completed on resurfacing projects.

Art. 703.06 Temporary Concrete Barrier 626 These signs may also be used in lieu of temporary pavement markings on low volume roads until it is practical and possible to install the permanent pavement markings.

If the road has an ADT less than 400, it is exempt from the requirements regarding no passing zone pavement markings.

703.06Method of Measurement. Short term pavement markings and

temporary pavement markings of the various line widths will be measured for payment in place in feet (meters). Double yellow lines will be measured as two separate lines.

The replacement of temporary pavement markings of the various line widths during winter shutdown periods will be measured for payment in feet (meters) as specified above, except only those pavement markings directed by the Engineer to be replaced will be measured for payment.

Letters and symbols used in conjunction with temporary pavement markings conforming to the sizes and dimensions specified will be measured for payment in square feet (square meters) according to the areas listed in Table 1, Section 780.

Short term and temporary pavement marking removal will be measured for payment in square feet (square meters).

703.07Basis of Payment. This work will be paid for at the contract unit price

per foot (meter) for SHORT TERM PAVEMENT MARKING or for TEMPORARY PAVEMENT MARKING - LINE of the type and width specified, and at the contract unit price per square foot (square meter) for TEMPORARY PAVEMENT MARKING LETTERS AND SYMBOLS of the type specified.

Removal of short term pavement markings, and pavement marking tapes applied as temporary pavement markings, will be paid for at the contract unit price per square foot (square meter) for SHORT TERM PAVEMENT MARKING REMOVAL. Removal of other materials applied as temporary pavement markings will be paid for according to Article 783.06.

When temporary pavement marking is shown on the Standard, the cost of the temporary pavement marking and its removal will be included in the cost of the Standard.

SECTION 704. TEMPORARY CONCRETE BARRIER

704.01Description. This work shall consist of furnishing, placing,

maintaining, relocating, and removing precast concrete barrier at temporary locations.

704.02Materials. Materials shall be according to the following

Item Article/Section

Temporary Concrete Barrier Art. 704.05 627

Note 1. Connecting pins and anchor pins shall be according to the requirements of ASTM F 1554 Grade 36 (Grade 250).

Note 2. Connecting loop bars shall be smooth bars according to the requirements of ASTM A 36 (A 36M).

CONSTRUCTION REQUIREMENTS

704.03General. Precast concrete barrier shall be the F shape as detailed on

the plans.

704.04Installation. The barriers shall be seated on bare, clean pavement or

paved shoulder and connected together in a smooth, continuous line at the locations provided by the Engineer.

Except on bridge decks, or where alternate anchoring details are shown on the plans, the barrier unit at each end of an installation shall be anchored to the pavement or paved shoulder using six anchor pins and protected with an impact attenuator as shown on the plans. When pinning of additional barrier units within the installation is specified, three anchor pins shall be installed in the traffic side holes of the required barriers.

Where both pinned and unpinned barrier units are used in a continuous installation, a transition shall be provided between them. The transition from pinned to unpinned barrier shall consist of two anchor pins installed in the end holes on the traffic side of the first barrier beyond the pinned section and one anchor pin installed in the middle hole on the traffic side of the second barrier beyond the pinned section. The third barrier beyond the pinned section shall then be unpinned.

Barriers located on bridge decks shall be restrained as shown on the plans. Anchor pins shall not be installed through bridge decks, unless otherwise noted.

Barriers or attachments damaged during transportation or handling, or by traffic during the life of the installation, shall be repaired or replaced. The Engineer will be the sole judge in determining which units or attachments require repair or replacement.

The barriers shall be removed when no longer required by the contract. After removal, all anchor holes in the pavement or paved shoulder shall be filled with a rapid hardening mortar or concrete. Only enough water to permit placement and consolidation by rodding shall be used and the material shall be struck-off flush.

704.05Method of Measurement. This work will be measured for payment in

feet (meters) in place along the centerline of the barrier. When the barrier is relocated within the limits of the jobsite, the relocated barrier will be measured for payment in feet (meters) in place along the centerline of the barrier.

Anchor pins, except for the six anchor pins for the barrier unit at each end of an installation, will be measured for payment as each, per anchor pin installed.
