546-1 Description.
Construct rumble strips in accordance with the details shown in the Plans and Standard Plans, Indexes 546-001, 546-010, and 546 -020.
546-2 Materials for Raised Rumble Strips.
546-2.1 Permanent Raised Rumble Strips : Construct permanent raised rumble strips
using one of the following:
546-2.1 1 Preformed Thermoplastic : Use only materials listed on the
Department’s Approved Product List ( APL), meeting the following requirements : Preformed Thermoplastic ....................... 971-1 and 971 -6 Ensure that the material used can be restored to its original dimensions by using a self bonding overlay meeting these requirements. Submit a certified test report to the Engineer indicating that the materials meet all r equirements specified.
546-2.1 2 Asphalt: Any plant -mixed hot bituminous asphalt mixture meeting the
requirements of a job -mix formula issued by the Department, except open -graded friction course.
546-2.2 Short -Term Raised Rumble Strips: Construct short -term raised rumble strips
meeting the requirements of 546 -2.1, or by using removable polymer striping tape meeting the requirements of 990 -9.
546-3 Application.
546-3.1 Permanent Raised Rumble Strips: Notify the Engineer before the placement of
raised rumble strips. Apply raised rumble strips having well defined edges. Remove and replace any raised rumble strips not meeting the requirements of the Contract Documents at no additional cost to the Departm ent. Before applying raised rumble strips, remove any material that would adversely affect the bond of the raised rumble strips by a method approved by the Engineer. Apply raised rumble strips only to dry surfaces, and only when the ambient air and surface temperature is at least 55ºF and rising. Before applying thermoplastic materials on portland cement concrete surfaces, apply a primer sealer recommended by the manufacturer. Prior to the application of any plant -mixed hot bituminous material, appl y a tack coat meeting the requirements of 300 -2.3. The mixture will be accepted on the basis of visual inspection by the Engineer with no further testing required.
546-3.2 Short -Term Raised Rumble Strips: Install short -term raised rumble strips
before opening to traffic, and in accordance with 546 -3.1. Maintain and remove short -term raised rumble strips until permanent raised rumble strips are installed.
546-3.3 Ground-In Rumble Strip :
546-3.3 1 General: Grind rumble strips that have well -defined edg es and smooth
interiors without tearing the finished pavement. On a daily basis, before opening the adjacent lane to traffic, ensure that all debris generated by the grinding process is removed and disposed of by vacuum or a method FY 2023-24 Return to Table of Contents approved by the Engin eer. Do not dispose of the debris within the right of way. Do not use the debris generated by the grinding process in recycled asphalt (RAP). Restore any pavement to the satisfaction of the Engineer, at no additional cost to the Department, when ground -in rumble strips do not meet the requirements of the Contract Documents.
546-3.3 2 Inspection : For limited access roadways, measure depth every one mile
during the grinding operation to monitor tolerances specified in Standard Plans , Index 546-010. For arterial and collector roadways, measure depth every 500 feet during the grinding operation to monitor tolerances specified in Standard Plans Index 546-020. If measurements are outside tolerances, immediately stop grinding operations and adjust grind ing machine to meet tolerances before continuing the grinding . Measure depth along the rumble strip centerline at the high and low point of the grinding pattern. Measure depth from top of pavement grade to top of ground-in surface. Measure, record and cert ify on a Department approved form and submit to the Engineer.
546-4 Method of Measurement.
The quantity of raised rumble strip sets to be paid for under this Section will be the Plan quantity per each, constructed and accepted. The quantity of ground -in rumble strips to be paid for under this Section will be the plan quantity in gross miles, constructed and accepted. No deduction will be made when the skip array is used.
546-5 Basis of Payment .
Price and payment will be full compensation for all work spe cified in this Section, including all surface cleaning and preparation, all debris disposal, furnishing of all materials, application, curing and protection of all items, protection of traffic, furnishing of all tools, machines, labor, and equipment, and all incidentals necessary to complete the work. Final payment will be withheld until all deficiencies are corrected. Payment will be made under: Item No. 546 - 71- Raised Rumble Strip Sets - each. Item No. 546 - 72- Ground-In Rumble Strips - per gross mile. FY 2023-24 Return to Table of Contents SECTION 548 RETAINING WALL SYSTEMS
548-1 Description.
Construct permanent and temporary retaining wall systems in accordance with this Section and in conformance with the lines, grades, design, and dimensions shown in the Contract or established by the Engineer. Sheet pile walls and cast -in-place walls are not included in this Section. Construct all walls of a specific type ( mechanically stabilized earth (MSE), counterfort, etc.), using the same wall system and supplier. If different t ypes of wall systems must be used in such a manner that causes one wall to interact with or influence another wall, coordinate the detailing of these areas of interaction/influence with the assistance of the Contractor’s Engineer of Record. Obtain each reinforced concrete precast concrete retaining wall system from a plant that is currently on the Department’s Production Facility Listing. Producers seeking inclusion on the list shall meet the requirements of Section 105. Ensure that each wall system compo nent is marked in accordance with 548 -5.3. Ensure that each shipment of products to the job site includes a signed or stamped delivery ticket in accordance with the Materials Manual, Section 8.2 Volume II, and the required written certification statement for each product shipped. Submit these tickets and certifications to the Engineer. When shown in the Plans or approved by the Engineer, a segmental block MSE retaining wall (SBW) system may be provided as a substitute for a reinforced concrete panel MSE w all system. All SBW systems must comprise:
1.Unreinforced dry -cast masonry facing blocks in a running bond pattern meeting the requirements of 548 -5.
2.Structural backfill reinforcement:
a.Type R -3 geosynthetic backfill reinforcement placed in sh eets full length without splices normal to the facing blocks and laterally without horizontal gaps, and with a vertical spacing of not more than every other course of blocks or 30 inches, whichever is less.
b.Metallic reinforcement placed full length w ithout splices normal to the facing blocks and spaced laterally and vertically not more than every other block or 30 inches, whichever is less, with a positive mechanical or shear connection to the facing blocks.
3.A mechanical shear connection to lock adjacent blocks together horizontally or vertically.
548-2 Materials.
Provide a wall system listed on the Department’s Approved Product List (APL) based on the wall type shown in the Plans. Purchase components, soil reinforcement, attachment devices, joint filler, filter fabric, and all necessary incidentals for each wall from the same wall supplier.
548-2.1 Concrete: Ensure that concrete utilized for all wall components is consistent
with the concrete class, environmental classification and admixture requirements for durability as stated in the Contract Documents . Produce and supply concrete for all reinforced concrete wall components meeting the requirements of Section 346. Produce and supply concrete for the leveling pad meeting the requirements of Section 347. Use Department approved mix designs. FY 2023-24 Return to Table of Contents
