Article 1 — Description
Construct milled rumble strips. This Item also includes filling rumble strips in asphalt and concrete pavement to provide a smooth, stable surface with the line and grade conforming to the adjacent pavement.
Article 2 — Materials
2.1 Filling Milled Asphalt Rumble Strips . Furnish materials in accordance with the following.
Item 300, “Asphalts, Oils, and Emulsions” Item 330, “Limestone Rock Asphalt Pavement” Item 334, “Hot -Mix Cold -Laid Asphalt Concrete Pavement” Item 34 1, “Dense- Graded Hot -Mix Asphalt” Item 350, “Microsurfacing” DMS -9202 , “Asphaltic Concrete Patching Material (Stockpile Storage or Bagged)”
2.2 Filling Milled Concret e Rumble Strips . Provide polymeric patching material in accordance with DMS -6170 ,
“Polymeric Materials for Patching Spalls in Concrete Pavement,” that is Type II material and matches the color of the pavement. The patching material must also meet the following minimum performance requirements: compressive strength at 24 hr. (ASTM C579, Method B): 4,500 psi; and must be able to carry traffic within 3 hr. of placement .
Article 3 — Equipment
3.1 Milled Rumble Strips . Provide a rotary -type cutting head with a maximum outside diameter of 24 in. and a
minimum length of 16 in. Arrange cutting tips to provide a relatively smooth cut with approximately 1/ 16-in. difference in texture deviation. Provide a cutting head with independent suspension from the power unit that will self -align with the shape of the surface and irregularities in the surface. Provide a cutting tool with guides to assure consistent alignment of each cut relative to the roadway and to provide uniformity throughout the project .
3.2 Filling Milled Asphalt Rumble Strips . Provide required or necessary equipment in accordance with
Item 320, “Equipment for Asphalt Concrete Pavement.” Use of other equipment may be permitted with written approval.
Article 4 — Construction
4.1 Milled Rumble Strips . Construct milled rumble strips in a uniform position according to dimensions and at
locations shown on the plans. The depressions must have well -defined edges, have a smooth interior finish, and not snag or tear the finished pavement. Control dust during grinding operations. Do not place rumble strips across exit or entrance ramps, acceleration and deceleration lanes, crossovers, gore areas, or intersections with other roadways, or at locations not shown on the plans. Correct misplaced rumble strips at the Contractor’s expense. Clean debris from the milled depressions by blowing with compressed air or flushing with water. Remove and dispose of debris by vacuuming or sweeping before opening the adjacent lane to traffic as directed. 814 4.2. Filling Milled Asphalt Rumble Strips . Place material in the milled areas in accordance with one of the following operations: Item 330, Grade FS; Item 334, Type F; Item 34 1, Type F; Item 350, or DMS -9202 .
4.3 Filling Milled Concrete Rumble Strips . Submit product specifications, product data sheet, and i nstallation
instructions from the manufacturer for approval before beginning work. Clean and prepare area to receive fill material in conformance with manufacturer’s specified instructions. Dry and abrasive blast the repair area to ensure it is free of moisture, dirt, grease, oil, or other foreign material that may reduce bond strength. Remove dust from the abrasive blasting operation. Apply duct tape in a symmetrical manner at the perimeter of the rumble strips to obtain a uniform appearance. Apply primer to surface where fill material is to be placed in conformance with manufacturer’s recommendations, and reapply primer if conditions change after initial application but before placing patching material. Mix, place, and cure material in conformance with manufacturer’s recommendations. Begin placement of material at the lower elevation of sloped areas. Screed polymeric patching material to conform to the roadway surface. Provide a non- skid finish using a notched trowel.
Article 5 — Measurement
5.1 Milled rumble strips. Measurement will be longitudinally along the roadway, by the foot. Measurement will
include only the actual work performed. Measurement will not include interruptions across ramps, acceleration or deceleration lanes, crossovers, gore areas, or intersections with other roadways .
5.2 Filling Milled Concrete and Asphalt Rumble Strips . Measurement will be longitudinally along the roadway,
by the foot, regardless of the rumble strip width or depth.
