00857.80 879 Section 00857 - Rumble Strips Description
00857.00 Scope - This Work consists of milling rumble strips by constructing indentations in asphalt
concrete surfaces as shown or directed. Equipment
00857.20 Equipment :
a.Longitudinal Rumble Strips - Construc t continuous or gap pattern longitudinal Shoulder , edge line, and centerline rumble strips as shown using a rotary type cutting head with a maximum outside diameter of 24 inches. Provide a cutting head length that matches the rumble strip width as shown. Arrange the cutting head cutting tips in a pattern that provides a relatively smooth cut with approximately 1/16 inch between peaks and valleys. Attach the cutting heads to the power unit in a manner that allows the tool to self -align with the Slopes of the Pavement and Shoulder and any irregularities in the Pavement and Shoulder surfaces. The cutting Equipment shall be capable of cutting rumble strips of the required width in a single Pass while moving in the same direction as the flow of traffic.
b.Transverse Rumble Strips - Form transverse rumble strips using a rotary type cutting head 5 1/2 inches long. Arrange the cutting head cutting tips in a pattern that provides a relatively smooth cut (approximately 1/16 inch between peaks and valleys). At tach the cutting heads to the power unit in a manner that allows the tool to self -align with the Slope of the travel lane and any irregularities in the travel lane surface. The cutting Equipment shall be capable of cutting rumble strips perpendicular to t he travel lane. Construction
00857.40 Construction - Where rumble strips will be constructed at the same locations where
permanent pavement markings will be installed, construct rumble strips within 3 weeks after temporary pavement markings have been placed for the final R oadway configuration, but before installing permanent pavement markings. After constructing the rumble strips, clean the Pavement by sweeping to remove dust and other foreign matter. Dispose of all materials according to 00290.20. Measurement
00857.80 Measurement - The quantities of longitudinal rumble strips will be measured on the length
basis, at least to the nearest 0.01 mile. Measurement will be made along each rumble strip run, regardless of location or width of strip with no deductions made for gaps in gap pattern rumble strips. Breaks in the rumble strips at intersections, interchange ramps, or other locations shown will not be measured for payment. The quantities of transverse rumble strips will be measured on the unit basis, by actual count of rumble strip clusters. 00857.90 880 Payment
00857.90 Payment - The accepted quantities of rumble strips will be paid for at the Contract unit
price, per unit of measurement, for the following items: Pay Item Unit of Measurement
a.Continuous Rumble Strips .....................................................................Mile
b.Gap Pattern Rumble Strips ....................................................................Mile
c.Transverse Rumble Strips ..................................................................... Each
d.Continuous Sinusoidal Rumble Strips ....................................................Mile
e.Gap Pattern Sinusoidal Rumble Strips ...................................................Mile Payment will be payment in full for furnishing all Material s, Equipment , labor, and Incidental s necessary to complete the Work as specified.
