740.07 Epoxy Pavement Marking

 

1. Specification:

Item 740.07 C&MS, NTPEP selected materials

For glass beads see 740.09.D

 

2. Sampling and/or Inspection Requirements:

 

Acceptance:

 

Materials intended for the Project or Purchase Order shall be inspected upon delivery. (Field)

 

All epoxy traffic paints must be on the approved list on the OMM web site at http://www.dot.state.oh.us/Divisions/ConstructionMgt/Materials/Approved-List/Pages/default.aspx.

Material not so listed must be rejected and removed from the project site.

 

Container markings shall be clearly legible, marked by stencil or stamp to indicate the volume , specification number, color, batch number, code number, with manufacturer's name and location. Markings missing, altered or placed by hand shall be cause for rejection.

 

Damaged containers shall be rejected.

 

Material is shipped with a TE-24. If the material fulfills the requirements it may be used immediately. If the material does not fulfill the requirements then it shall be rejected.

Materials delivered without a proper TE-24 will mean the materials are unidentifiable and are to be sampled conforming to Supplement 1089 procedures, including number of samples and documentation.  Approval of unidentifiable materials will be based on Laboratory testing of field samples submitted for each batch of traffic marking materials. 

 

Epoxy Pavement Marking Procedure

1. Check the Approved List to see the epoxy paint to be sampled is listed on the Approved List

2. Have the contractor load the application equipment.

3. Put on leather protective gloves and eye protection.

4. Have the contractor shut off all pressure spray system.

5. Using a clean one quart (4.75"x4.25") wide mouth metal can, take a sample for the resin component from the resin component line prior to mixing.

a. Fill the can completely.

6. Remove the can. Tap the lid securely on with a hammer. Seal the lid with duct or packing tape.

7. Repeat items 5 and 6 to obtain an additional sample of the resin component.

8. Using a clean one quart (4.75"x4.25") wide mouth metal can, take a sample for the hardener component from the hardener component line prior to mixing. a. Fill the can completely.

9.  Remove the can. Tap the lid securely on with a hammer. Seal the lid with duct or packing tape.

10.  Repeat items 8 and 9 to obtain an additional sample of the hardener component.

11.  Tape a TE-31 tag on the quart containers with the following information:

          Epoxy Paint producer   

          Epoxy Paint specification

          Epoxy resin batch number or Epoxy hardener batch number [depending on which can you are labeling]

          Epoxy brand name and manufacturer’s ID [from the Approved List]

          Date of manufacture

          Shelf life

          Project number and year

          ODOT Sample number

          Date sampled

12.  Immediately ship one sample of the resin component and one sample of the hardener component to Central Laboratory, Chemical Section.

13.  Give the other samples to the contractor.
