02577 - 3/3 marking of specified thickness and width and capable of resisting deformation. E. The portion of the pavement surface or thermoplastic marking to which the marker is attached by the adhesive shall be cleaned of dirt, curing compound, grease, oil, moisture, loose or unsound pavement and any other material which would adversely affect the adhesive. Reflective markers shall be installed in such a manner that the reflective face of the marker is perpendicular to a line parallel to the roadway centerline. No markers shall be installed over longitudinal or transverse joints of the pavement surface. The adhesive shall be spread on the bonding surface (not the marker) so that 100 percent of the bonding area of the marker will be covered. The adhesive application shall be sufficient thickness so that when the marker is pressed into the adhesive, excess adhesive shall be forced out around the entire perimeter of the marker. All excessive adhesive shall be removed from in front of the reflective faces, if any adhesive or foreign matter adheres to the reflective face of the marker, the marker shall be replaced. The ENGINEER shall determine the minimum time necessary to cure the adhesive for sufficient set to bear traffic. 3.02 SIGN FABRICATION A. Preparation of sign blanks and fabrication of reflectorized faces shall conform to the applicable requirements of DOT Section 700-4 and 700-5. 3.03 INSTALLATION A. Sign and supports shall be erected in conformance to DOT requirements and as specified herein. B. All damaged signs and reflective pavement markers and traffic stripes and markings shall be replaced in conformance with this Section and DOT requirements. 3.04 WEATHER LIMITATIONS: The CONTRACTOR shall not apply paint when any moisture is present on the surface to be painted or when the air temperature is below 40 degrees F. Painting shall not be done when winds are sufficient to cause spray dust. 3.05 CORRECTED MEASURES: All painted stripes, which fail to meet the specifications including the permissible tolerances and appearance requirements, or are marred or damaged by traffic or from other causes, shall be corrected by the CONTRACTOR at its sole expense. All drips and spattered paint shall be removed to the satisfaction of the ENGINEER. Whenever it is necessary to remove paint, it shall be performed by sand blasting or by any other means, which will not damage the underlying surface of the pavement as approved by the ENGINEER.
