2. Sampling and/or Inspection Requirements:

Acceptance:

All paints intended for the Project or Purchase Order shall be inspected upon delivery. Containers shall be clearly marked to indicate the number of gallons [liters], specification number, color, batch number, code number, with manufacturer's name and location.

 

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

 

Paint shall be capable of being broken up by mixing to a smooth, uniform consistency and shall not liver, thicken, curdle, gel, or hard settle nor show any other objectionable properties in a mixed, freshly opened container.

 

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.
