driving aids. This work shall consist of installing audible roadway delineators where indicated on the contract documents.

649-2 MATERIALS. None specified.

649-3 Construction Details

649-3.01 Milled -In Audible Roadway Delineators (MIARDs).

A.Equipment. The construction equipment shall include a rotary type cutting head capable of cutting the MIARD depressions to the dimensions and at the spacing indicated on the Standard Sheets. The pattern of cutting tips on the head shall be arranged to produce a relatively smooth cut with approximately 1/16 inch between peaks and valleys. Prior to beginning full production work on asphalt shoulders, the Contractor shall demonstrate to the Engineer the ability to achieve the desired surface without tearing or snagging the asphalt to be milled. The cutting head shall be on its own suspension system, independent from that of the power unit, to allow the head to align itself with the slope of the shoulder and/or any irregularities in the shoulder surface. The cutting tool shall be equipped with gui des or a guidance system, clearly visible to the operator, to provide for consistent alignment of each MIARD at the offsets from traveled way indicated on the project plans. Where directed by the Plans or EIC to mill in MIARDs in areas marked with crosshat ching, the spacing of the MIARDs shall be adjusted to minimize damage to the markings. No milling shall be done within 4 inches of transverse joints.
B.Installation and Dimensions. The finished MIARDs shall conform to the dimensions and spacing shown on the Standard Sheets. The milling machine shall be capable of grinding to within 3 feet of an obstruction. The offset from traveled way may be changed at the EIC's discretion. At the end of each working day, the Contractor shall remove all equipment to a location where it does not present a hazard to traffic. The pavement shall be cleaned by sweeping and the work area shall be reopened to traffic. The milled material shall be t horoughly removed from the shoulders. In uncurbed areas, the millings may be swept off the shoulder to serve as shoulder back -up material. In curbed areas, millings shall be removed from the project and disposed of in an acceptable manner.

649-3.02 Centerline Audible Roadway Delineators (CARDs).

A.Scheduling and Coordination. Because of the need to promptly replace pavement markings and reopen the highway to traffic, milling of CARDs shall not be conducted when conditions would not allow pavement markings to be placed soon after. To facilitate prompt placement of pavement

649-3 03

NEW YORK STATE DEPARTMENT OF TRANSPORTATION Section 600 STANDARD SPECIFICATIONS (USC) January 1, 202 4 VOLUME 3 markings by either the Department’s pavement marking crews or the Contractor as indicated in the contract documents, all work shall be done between April 1 and November 30 Downstate (in the counties of Dutchess, Orange, Rockland, Putnam, Westchester, Nassa u, Suffolk, and the City of New York) and between May 1 and October 31 Upstate (all other counties). If the contract documents indicate that pavement markings will be installed by the Department, the Contractor shall inform the Engineer of the planned work schedule and the Engineer will coordinate with the Department’s pavement marking crew chief. If the contract documents indicate that pavement markings will be installed by the Contractor, pavement markings shall be installed within three calendar days, measuring from the date on which the markings at that point were first removed. Gaps: Prior to milling, the Contractor shall obtain EIC approval on where CARDs are to be installed and where gaps are to be included.

B.Timing of CARD Placements. New asphalt pavement should be allowed to harden for at least 24 hours before CARDs are milled in, so that the milling machine does not tear the asphalt and so that asphalt does not build up on the cutters. Temporary Pavement Markings, in conformance with Section

619-3 06, shall be installed during this hardening period. If tape is used, it shall be removed before

milling commences. After the CARDs have been milled and the millings have been removed, the permanent pavement mark ings can be installed.

C.Equipment. The construction equipment shall include a rotary type cutting head capable of cutting the CARD depressions to the dimensions and at the spacing indicated on the Standard Sheets. The pattern of cutting tips on the head shall be arranged to produce a relatively smooth cut with approximately 1/16 inch between peaks and valleys. Prior t o beginning full production work, the contractor shall demonstrate to the Engineer the ability to achieve the desired surface without tearing or snagging the asphalt. The cutting head shall be on its own suspension system, independent from that of the power unit, to allow the head to align itself with the slope of the pavement and/or any irregularities in the surface. The cutting tool shall be equipped with guides or a guidance system, clearly visible to the operator, to provide for consistent alignment of each CARD relative to the centerline markings.
D.Installation and Dimensions. The Contractor shall provide Work Zone Traffic Control as indicated in the contract documents. CARDs shall be installed within the limits indicated in the contract documents. Unless indicated otherwise in the contract documents, CARDs shall be centered on the middle of the centerline marking pattern. No milling shall be done within 4 inches of sawn and sealed transverse joints. CARDs shall not be carried through any intersection where the CARD’s direction of travel is controlled by a yield sign, stop sign, or traffic light, or would encounter crosswalks. In those instances, the CARD shall stop before any stop line or crosswalk. CARDs shall not be carried through any crosswalks or across any concrete bridge deck or concrete culvert surface. Treatment for left turn lanes shall be as shown on the Standard Sheets. At the end of each working day, the Contractor shall remove all equipment to a location where it does not present a hazard to traffic. The pavement shall be cleaned by sweeping and the work area shall be reopened to traffic. Millings shall be thoroughly re moved from the work area and disposed of in an acceptable manner.

649-3.03 Secondary Highway Audible Roadway Delineators (SHARDs).

A.Equipment. The construction equipment shall include a rotary type cutting head capable of cutting the SHARD depressions to the dimensions and at the spacing indicated on the Standard Sheets. The pattern of cutting tips on the head shall be arranged to produce a relat ively smooth cut with approximately 1/16 inch between peaks and valleys. Prior to beginning full production work

649-3 03

NEW YORK STATE DEPARTMENT OF TRANSPORTATION Section 600 STANDARD SPECIFICATIONS (USC) January 1, 202 4 VOLUME 3 involving asphalt pavement, the Contractor shall demonstrate to the Engineer the ability to achieve the desired surface without tearing or snagging the asphalt. The cutting head shall be on its own suspension system, independent from that of the power unit, to allow the head to align itself with the slope of the pavement and/or any irregularities in the shoulder surface. The cutting tool shall be equipped with gui des or a guidance system, clearly visible to the operator, to provide for consistent alignment of each SHARD.

B.Installation and Dimensions. The Contractor shall provide Work Zone Traffic Control as indicated in the contract documents. SHARDs shall be installed within the limits indicated in the contract documents unless the limits are adjusted by the Engineer to meet existing field conditions. No milling shall be done within 4 inches of sawn and sealed transverse joints or longitudinal joints. SHARDs shall not be installed on bridge decks, concrete culvert surfaces, through crosswalks, through highway intersections, across commercial driveways, or as identified on the Plans or designated by the Engineer. SHARDs shall not be milled in ove r deteriorating pavement. Instead, the SHARDs should be placed 4 inches away from the deterioration, provided the remaining shoulder width is at least 3’ -6” and the length of that reduced width does not exceed 100 feet for any given deteriorated area. Wher e the line of SHARDs must be moved away from traffic, the transition should, to the extent practicable, be gently flared to maintain a smooth line. As the work progresses, any portions of the shoulder or pavement that will accommodate traffic during the construction effort shall be cleaned by sweeping or flushing and the work area shall be reopened to traffic. At the end of each working day, the Contr actor shall remove all equipment to a location where it does not present a hazard to traffic. The milled material shall be thoroughly removed from the shoulders. In areas with curbs or adjacent lawns or businesses, millings shall be removed from the projec t and disposed of in an acceptable manner. In uncurbed areas with no adjacent lawns or businesses, the millings may be swept off the shoulder to serve as shoulder back -up material.

649-4 METHOD OF MEASUREMENT. Audible Roadway Delineators will be measured as the sum of

the lengths in linear feet of the individual segments where audible roadway delineators have been satisfactorily installed. For milled -in audible roadway delineators, lengths will be measured along the inside edge of the shoulder from the center of the first milled -in audible roadway delineator in a segment to the center of the last milled -in audible roadway delineator in that segment. Where milled -in audible roadway delineators are provided on more than one shoulder, lengths will be measured separately for each segment and added to the sum. Individual gaps and exclusions under 100 feet in length will be included in segments identified for payment. Individual gaps and exclusions 100 feet or more in length will be excluded from segments identified for payment. For centerline audible roadway delineators, lengths will be measured along the centerline of the CARDs from the center of the first centerline audible roadway delineator in a segment to the center of the last centerline audible roadway delineator in that s egment. Individual gaps and exclusions under 100 feet in length will be included in segments identified for payment. Individual gaps and exclusions 100 feet or more in length will be excluded from segments identified for payment. For secondary highway audible roadway delineators, lengths will be measured along the outside edge of the SHARDs from the center of the first SHARD to the center of the last SHARD. Individual gaps and exclusions under 300 feet in length will be included in segments identified for payment. Individual gaps and exclusions 300 feet or more in length will be excluded from segments identified for payment.

649-5 BASIS OF PAYMENT. The unit price bid shall include the cost of all materials, equipment and

labor necessary to satisfactorily complete the work. Payment will be made under:

650-1 DESCRIPTION. Under this work the Contractor shall furnish and install a casing by trenchless

installation methods in accordance with the contract documents and as directed by the Engineer. T he casing length, type, and size shall be as indicated in the contract documents. Acceptable methods of trenchless installation include Auger Boring, Slurry Boring, Pipe Jacking, Microtunneling, or Horizontal Directional Drilling. Pipe Ramming or Soil Compaction methods will not be allowed. For an installation under a railroad, methods which leave an uncased bore hole t hrough the embankment will not be allowed.

650-1.01 Definitions. The following definitions were obtained from the NCHRP Synthesis 242

Trenchless Installation of Conduits Beneath Roadways.

A.Auger Boring (AB). A technique that forms a bore hole from a drive shaft to a reception shaft by means of a rotating cutting head. Spoil is transported back to the drive shaft by helical -wound auger flights rotating inside a steel casing that is being jacked in place simulta neously. AB may provide limited tracking and steering capability. It does not provide continuous support to the excavation face. AB is typically a 2 -stage process (i.e., casing installation and product pipe installation).
B.Slurry Boring (SB). A technique that forms a bore hole from a drive shaft to a reception shaft by means of a drill bit and drill tubing (stem). A drilling fluid (i.e., bentonite slurry, water, or air pressure) is used to facilitate the drilling process by keeping the drill bi t clean and aiding with spoil removal. It is a 2 -stage process. Typically, an unsupported horizontal hole is produced in the first stage. The pipe is installed in the second stage.
C.Pipe Jacking (PJ). A technique for installing a prefabricated pipe through the ground from a drive shaft to a reception shaft. The pipe is propelled by jacks located in the drive shaft. The jacking force is transmitted through the pipe to the face of the PJ excavation. The e xcavation is accomplished, and the spoil is transported out of the jacking pipe and shaft manually or mechanically. Both the excavation and spoil removal processes require workers to be inside the pipe during the jacking operation.
D.Microtunneling (MT). A remotely controlled, guided pipe -jacking process that provides continuous support to the excavation face. The guidance system usually consists of a laser mounted in the drive shaft communicating a reference line to a target mounted inside the MT machine’ s articulated steering head. The MT process provides ability to control excavation face stability by applying mechanical or fluid pressure to counterbalance the earth and hydrostatic pressures.
E.Horizontal Directional Drilling (HDD). A 2-stage process that consists of drilling a small diameter pilot directional hole along a predetermined path and then developing the pilot hole into a suitable bore hole that will accommodate the desired utility and then pulling the utility into place. T he HDD process provides the ability to track the location of the drill bit and steer it during the drilling process. The vertical profile of the bore hole is typically in the shape of an arc entrapping drilling fluid to form a slurry pathway rather than an open hole. This entrapped slurry provides continuous support to the bore hole.
