(Rationale: Sec 620 is being revised to convert to performance related specification. During the performance review process, special provisions for snowplowable raised pavement markers, epoxy pavement marking paint, acrylic copolymer pavement marking paint, and acrylic waterborne pavement marking paint underwent the performance review process and were incorporated into Sec 620.)
3/24/02 - EPC requested that Operations evaluate the minimum initial Retroreflectivity numbers for this next construction season, and make adjustments in the numbers in the future as required.
5/28/03 - Jim Brocksmith has discussed concerns with Don Hillis, no changes were required to answer his questions.
8/27/03 - Revised 620.10 Preformed Marking Tape to include a type 1 and a type 2 tape. Type 2 tape specifications have been included in 1048.
8/29/03 - Minor rewording of 620.90.2 concerning epoxy marking.
10/23/03 - Revisions to 620.2.1.7, 620.2.2.4, 620.3.7, 620.2.3.2and 620 20.3.8 based on comments from the Chief Engineer. Revisions have been discussed with and approved by Don Hillis.
01/21/04 Following revisions made per email request:
Section 620.2.2.2 refers to section 620.2.4 in regards to temporary pavement marking. Section 620.2.5 is the actual section for temporary pavement marking.
Section 620.2.6 refers to section 620.2.4 as pertaining to traffic pattern other conditions. Section 620.2.4 refers to the acceptance of pavement marking materials.
Section 620.10.2 shows the section for preformed pavement marking tape as 1048.2. In the new performance section 1048, there is no section 1048.2. This should be 1048.10.
Section 620.20.2 shows the section for extruded thermoplastic as 1048.3. This should be 1048.20.
Section 620.20.2 shows the section for drop-on glass beads as 1048.6. This should be 1048.50.
Section 620.30.2 shows the section for preformed removable marking tape as 1048.4. This should be 1048.30.
Section 620.40.2 shows the section for preformed short term marking tape as 1048.5. This should be 1048.40.
Section 620.50.2 shows the incorrect sections for all of the items. They should be 1048.50 for the beads, 1048.100 fro the copolymer and 1048.110 for the waterborne.
Is the 15 mil thickness in section 620.50.3.4.3 wet or dry film thickness. The second sentence seems to imply wet.
620.50.3.4.3 Paint shall be applied to a minimum thickness of 15 mils (0.4 mm). The wet film thickness of the applied paint shall be tested with a paint thickness gauge as directed by the engineer.
The intention is wet mil thickness. I've modified the first sentence to read: Paint shall be applied to a minimum wet thickness of 15 mils (0.38 mm).
Section 620.70.2 shows the section for preformed short term marking tape as 1048.7. This should be 1048.60.
Section 620.80.2 shows the wrong sections for drop-on glass beads and hot spray thermoplastic.. These should be 1048.50 for the beads and 1048.70 for the hot spray.
Section 620.80.3.2.4 needs the conversion from English to Metric recalculated. 5 mils = .127mm.
Section 620.80.3.2.5 makes reference to section 620.2.3.2.1. I believe the section referenced should be 620.2.4.1.
Done, thanks. I did however make the reference only to 620.2.4 since this is how the other sections refer to the minimum initial numbers.
Section 620.90.2 shows the wrong sections for epoxy pavement marking material and drop-on glass beads. These should be 1048.90 for the epoxy and 1048.50 for the beads.
Section 620.90.2.1 references section 620.2.1.4. There is no such section as 620.2.1.4.
There is a section 620.2.1.4 and it refers to the contractor protecting the line during its cure, so this is correct.
Section 620.100.2 shows the section for snowplowable raised pavement markers as 1048.9. This should be 1048.80.
Section 620.110.2 shows the section for snowplowable raised pavement markers as 1048.9. This should be 1048.80.

Temporary raised pavement markers shall be in accordance with Sec 620.70. Sign WO8-12, "No Center Stripe", shall be installed throughout the section where the striping has been obliterated at one-half mile (1 km) intervals and 150 feet (45 m) from side roads or as shown on the plans. These signs shall be displayed only where the striping has been obliterated and shall be removed or covered where final striping is complete.
620.2.3.4 On resurfacing projects, when the adjacent layer of resurfacing has not been placed and the existing centerline or lane line marking has been obliterated, the temporary marking shall be placed on the higher layer at the centerline of the roadway or lane. Any temporary pavement marking damaged, displaced or missing before installing the final pavement marking is placed shall be replaced by the contractor at the contractor's expense.
620.2.34 Inspection and Acceptance.
620.2.34.1 Initial Inspection. Permanent pavement marking will be inspected following installation. The engineer will measure the initial retroreflectivity, with a mobile retroreflectometer. , a minimum of Measurements will be taken no sooner thanbetween seven and forty-five days after, and within no later than 4514 days of after application. If traffic control is required as determined by the engineer, the contractor shall provide approved traffic control at the contractor's expense.
620.2.34.1.12 If the initial performance inspection discloses any permanent pavement marking, in whole or in part, which does not meet the acceptance requirements, the contractor shall, at the contractor's expense, repair or replace such work to the satisfaction of the engineer within 30 days of notification. If more than 50 percent of any lane line, centerline or edge line is required to be replaced, all of the pavement marking on that lane line, centerline or edgeline shall be replaced in accordance with this specification at the contractor’s expense. To liquidate the costs and risks for each subsequent replacement of any of that pavement marking, the unit price for the line items of pavement marking replaced will be reduced by 25 percent. In the event of a fifth replacement, the unit price for that type of pavement marking replaced is zero.Only one replacement will be allowed without any deductions in pay being assessed. Each s will constitute an additional 25 percent deduction from the contract unit price for this work.
