Article 1 — Description
Furnish and place retroreflectorized or non-reflectorized (contrast) prefabricated pavement markings and rumble strips .
Article 2 — Materials
Furnish Type B and Type C prefabricated pavement marking materials in accordance with DMS -8240 , “Permanent Prefabricated Pavement Markings.” Type B prefabricated pavement markings have a backside pre- coated with a pressure- sensitive adhesive to affix the marking to the roadway surface. Type C prefabricated pavement markings are heat -applied and may require additional beads applied during application. Furnish prefabricated pavement marking materials used for contrast markings in accordance with DMS -8240 , except that the color requirement for the black contrast portion does not have to meet the color requirements specified for white or yellow markings. Store all materials in a weatherproof enclosure and prevent damage during storage. Provide prefabricated rumble strips from manufacturers listed on the Department ’s MPL.
Article 3 — Construction
3.1 General . Obtain approval for the sequence of work and estimated daily production. Remove all waste
generated from the jobsite before the end of each working day. Establish guides to mark the lateral location of pavement markings as shown on the plans or as directed and have guide locations verified. Use guide material that will not leave a permanent mark on the roadway. Place material in alignment with the guides without deviating from the alignment more than 1 in. per 200 ft. of roadway or more than 2 in. maximum and with no abrupt deviations.
3.2 Placement Limitations.
3.2.1 Moisture . Apply material to pavement that is completely dry. Pavement will be considered dry if, on a sunny
day after 15 min., no condensation occurs on the underside of a 1-sq. ft. piece of clear plastic that has been placed on the pavement and weighted on the edges.
3.2.2 Temperature. Follow pavement and ambient air temperature requirements recommended by the material
manufacturer. Do not place material when the pavement temperature is below 60°F or above 120°F if the material manufacturer does not establish temperature requirements.
3.3 Dimensions . Place material in conformance with the color, length, width, shape, and configuration shown on
the plans. Locate alignment as shown on the plans or as directed.
3.4 Methods . Place all materials in conformance with the material manufacturer’s instructions, as well as the
surface condition, moisture, and temperature requirements in accordance with this Item, unless otherwise directed. 916 3.5. Surface Preparation . Prepare surface using any approved cleaning method that effectively removes contaminants, loose materials, and conditions deleterious to proper adhesion. Abrasive or water -blast cleaning is not required unless otherwise shown on the plans. Blast clean, when required, in accordance with Item 678, “Pavement Surface Preparation for Markings.” Prepare surfaces further after cleaning by sealing or priming as recommended by the pavement marking material manufacturer or as directed. Use adhesive, when required, of the type and quality recommended by the pavement marking material manufacturer. Do not clean concrete pavement surfaces by grinding.
3.6 Performance Requirements.
3.6.1 Dura bility . Provide materials that do not lose more than 5% of the material in any 1- ft. section. Measure the
durability in accordance with ASTM D913.
3.6.2 Adhesion. Ensure the material does not lift, shift, smear, spread, flow, or tear by traffic action.
3.6.3 Appearance. Ensure the material present s a neat, uniform appearance that is free of excessive adhesive,
ragged edges, and irregular lines or contours.
3.6.4 Visibility . Ensure Type B and Type C ma rkings have uniform and distinctive retroreflectance when inspected
in accordance with Tex-828-B .
3.7 Performance Period . All mater ial must meet the requirements of this Item for at least 30 calendar days after
installation. Remove and replace all material that fail s to meet requirements at the Contractor’s expense, unless otherwise directed. Replace failing material within 30 days of notification. All replacement material must also meet all requirements of this Item for at least 30 calendar days after installation.
Article 4 — Measurement
This Item will be measured by the foot, with longitudinal markings measured longitudinally and transverse markings measured transversely, or by each word, shape, or symbol. Rumble strips will be measured transversely across the roadway on which the rumble strip is installed. Measurement will include all strips of material placed across the roadway surface. This is a plans quantity measurement Item. The quantity to be paid is the quantity shown in the proposal , unless modified by Article 9.2., “Plans Quantity Measurement.” Additional measurements or calculations will be made if adjustments of quantities are required.
Article 5 — Payment
The work performed and materials furnished in accordance with this Item and measured as provided under “Measurement” will be paid for at the unit price bid for “Prefabricated Pavement Markings” of the type , color , shape, width, and size specified as applicable, or “Prefabricated Rumble Strips” of the type, color , and width specified as applicable. This price is full compensation for cleaning the pavement by any means other than required abrasive or water- blast cleaning or milling; furnishing and placing materials; and equipment, labor, tools, and incidentals. Abrasive or water -blast cleaning and milling, when shown on the plans, will be paid for under Item 678.
