TTC Devices: added When any provisions of this Specification or the Plans do not meet the minimum requirements of the MUTCD, the MUTCD shall control. The 2009 Edition of the MUTCD shall be in effect for the duration of the project. All traffic control devices used during the construction of the project shall meet the Standards utilized in the MUTCD, and shall comply with the requirements of these specifications, Georgia Construction Standards and Details, Project Plans, Design Manuals, and Special Provisions.

TTC Devices: added

WTCS: Modified WTCS can be a subcontractor (not an employee of the Prime Contractor) WTCS will required active certification from NSC, or ATSSA ( no resume needed) WTCS will preform more inspections (monthly on all roadway/ weekly on interstates) New more detail TC-1

MASH Requirement: added In addition, temporary work zone devices, including portable barriers, manufactured after December 31, 2019, must have been successfully tested under 2016 edition of MASH requirements. Such devices manufactured on or before this date, and successfully tested under either NCHRP Report 350 or the 2009 edition of MASH, may continue to be used throughout their normal service lives.

MASH Requirement: added This is only for TTC devices. Other items have other milestones

TTC Devices – QPL: clarified All traffic control devices with applicable Qualified Products List (QPL) categories shall come from the appropriate approved list. 2. Products not on the QPL may be used with an approval letter from the Georgia Department of Transportation Office of Materials. 3. If there are no applicable QPL, the Contractor shall provide proof of MASH/NCHRP 350 certification. The proof may be a letter or written statement from the manufacturer that the product is MASH/NCHRP 350 approved. Decal certifications are not proof of certification and are not required.

Quality Guideline for all Temporary Traffic Devices: new

Retroreflectivity: new A. Signs 1. For all projects let prior to and including April/May 2018, signs can be: a. All rigid fluorescent orange construction warning signs (black on fluorescent orange) shall meet the minimum retroreflectivity and color requirements of ASTM Type VII, VIII, IX or X regardless of the mounting height. . b. Warning signs (W3-1a) for stop conditions that have rumble strips located in the travel lane shall be reflectorized with ASTM Type IX fluorescent yellow sheeting. c. All other signs shall meet the requirements of ASTM Type III or IV except for “Pass With Care” and “Do Not Pass” signs which may be ASTM Type I unless otherwise specified 2.

All other signs reflectorization shall be in accordance with the plans, contract, and “GDOT Signing and Marking Design Guidelines”. 3. Reflective sheeting should meet the requirements of Section 913 and QPL-29.

Retroreflectivity: new Channelization Devices For all projects let prior to and including April/May 2018, channelization devices shall meet the minimum requirements of ASTM Type III or IV high intensity sheeting. For all projects let May/June 2018 and afterward, all channelization devices (white/ fluorescent orange and white/red) shall meet the minimum retroreflectivity requirements of ASTM D4956 Type VI. 3. Reflective sheeting should meet the requirements of Section 913 and QPL-29.

Retroreflectivity: new

Retroreflectivity: new 2) TTC Devices: ASTM D4956 Type VI

TTC Devices: modified Traffic Drums: Vertical Panels: Type VI/ fluorescent orange/6” stripes/No orange band Vertical Panels: Type VI/ Fluorescent orange/6” stripes Can be used for longitudinal channelization in activity zone. No reduction in lane (<10’) req.

TTC Devices: modified Cones: Posts: Prohibited on Interstates/ Daylight use only/Can be use for flagging taper Posts: Square Tube and/or galvanized U-channel No wood posts

TTC Devices: modified Signs: - Construction Signs Type XI (Construction Signs) Rigid (not roll-up signs) Substantially plumbed and leveled Signs shall be visible and legible

TTC Devices

Pavement Marking: modified All Traffic Striping (≤ 45 days): min 4” wide All Temporary Striping (> 45 days): Intermediate surfaces min 5” wide Final surface overlaid/grinded min 5” wide All Temporary Striping on Final Surface: min 4’ wide

Clear Zone: new Clear Zone: 30 ft. GA 4000W (<=> 30 ft.) 6ft. Urban Area (curb and gutter) Equipment/Material/ TTC devices

Highway Work Zone: modified Req “reduce speed limit sign” Additional speed limit signs R2-1 Variable speed limit: VSL sign control the speed/ no R2-1 signs Request that speed limit be restricted to max 55 mph when working.

Shoulder Closure: new Shoulder Closures = Lane Closure Shoulder Closure require Engineer approval Restricted to two miles Shoulder Closures (MUTCD) Advance signing Tapers

Traffic Pacing: modified Increase time to 20 minutes Deleted static sign. / PCMS is required

Flagging Operations: modified Only two organization for certification: American Traffic Safety Association (ATSSA) National Safety Council (NSC) Flaggers require a min. Performance Class 3
