	Where possible, if the prime contractor agrees, 3M should be allowed to place either temporary or permanent pavement marking prior to partial acceptance of a project. This should definitely be pursued if the prime contractor’s pavement marking subcontractor is a 3M subcontractor. If a 3M subcontractor does install either 3M tape or temporary paint in lieu of temporary raised pavement markers, the temporary pavement marking quantities on the prime contract should be underrun, since 3M is responsible for paying the subcontractor to perform this work. When 3M pavement markings are placed on a segment of roadway prior to partial acceptance of that segment of the project, the prime contractor should be held accountable for costs to repair any damaged 3M tape as a result of the contractor’s operations or diligence until acceptance, partial or final, of that segment of roadway. Damage to 3M tape due to normal traffic operations should be handled in accordance with the conditions of the 3M tape warranty.

	Temporary pavement marking paint placed by 3M should have minimum initial retroreflectivity readings of 150 mcd/m<sup>2</sup>/lux. Temporary pavement marking paint, due to weathering and normal deterioration, should be restriped when retroreflectivity readings average below 100 mcd/m<sup>2</sup>/lux or when more than 5 percent of the paint stripe is missing in a section of pavement or when 50 percent or more of a 10 ft. lane line is missing. Retroreflectivity readings should be measured using portable hand-operated retroreflectometers. If the temporary pavement marking paint does not meet the minimum requirement, then a request should be sent to the Construction and Materials Division for restriping using the same [[Media:620.12 ~~3MStripeRequestForm2009~~.xls\|3M Request Form]] as when initially requesting 3M striping for a project. Upon receipt, 3M will complete the restriping within five days of notification, weather permitting.

If for safety reasons it is determined remobilization is necessary, such requests with documentation should be submitted to Construction and Materials for approval prior to requesting remobilization of a 3M subcontractor that will incur costs to MoDOT.

	Final installation of 3M tape should be within the guidelines set forth in the 3M contract (Appendix A). Surface preparation, including grooving, and installation of marking materials outside of the allowed tolerances should be corrected as follows. Surface preparation, including grooving, beyond the allowed tolerances should be sealed. If emulsion asphalt is used, it should be diluted with equal parts of water at a rate in accordance with [http://modot.mo.gov/business/standards_and_specs/Sec0407.pdf ~~Section~~ 407 of the Standard Specifications] to achieve total coverage, and excess emulsion should be blotted with sand prior to opening to traffic. Any 3M tape installations outside the given tolerances should be removed and replaced with new 3M tape material.

	Initial minimum retroreflectivity for 380I-WR (Type 2 tape) or 380I-5WR (contrast tape) series tape should be 500 mcd/m<sup>2</sup>/lux. The initial minimum retroreflectivity for installations of 380I-WR should have an average minimum initial dry reflectivity of 500 mcd/m<sup>2</sup>/lux. Within 30 days after the material is placed, 3M will provide a minimum of 10 regularly spaced initial reflectivity readings per roadway segment in a mutually agreed format. Do not wait for the retroreflectivity value readings to accept 3M tape. If upon receipt, the retroreflectivity values are below the above values, notify the Construction and Materials Division for corrective action.
