Testimonials: Traffic Overlay Markers
Kansas DOT: The Kansas DOT specifies temporary pavement marking tape for project temporary striping. This tape is to be removable so that conflicting lines will not result after changing from one phase to another or changing from temporary marking to permanent. The problem with this material is that on tined bridge decks or concrete pavements the striping material does not seem to adhere very well. In fact, when it rains the water gets into the tines and dislodges the tape.
On a recent project, this problem continued to occur. As a last ditch effort, the contractor placed the flexible overlay markers over the bridge without permission. These flexible markers stayed for a long period of time and when they were damaged, they were easy to replace... This office would like to see these flexible overlay markers become a part of the KDOT's traffic control plan.
PENNSYLVANIA DOT
Pennsylvania DOT: The TOMs provided good to excellent reflectivity and delineation, especially during the hours of darkness when the pavement was wet. The required five (5) foot spacing seemed to be the correct spacing to depict a solid lane line. The installation and removal of the TOM was accomplished with no apparent difficulty. The total cost savings of using the TOM in lieu of temporary removable pavement marking tape was approximately $130,000 on this particular project.
California DOT: Field review has led to the determination that the use of approved day/night raised reflectorized pavement markers, spaced at six (6) foot centers, will provide good delineation for left edge lines. Headquarters Office Engineers will develop a Standard Special Provision to allow the marker pattern as an option to standard lines... Early implementation of this new provision could be quite cost beneficial, particularly where temporary "removable" pavement marking tape would normally be required.
Tillamook County: Today I had the privilege of using some of your overlay traffic markers (stick & stomp’s). Our county usually uses pavement tape for temporary pavement marking after overlaying operations. Today we found ourselves not being able to put the last lift of pavement on because of rain. Our engineer did not want to use the marking tape as it presented an adhesion problem for the final overlay and that it was hard to remove. I found a contractor who was working a paving job on the state highway nearby and talked him into trade for some of your markers. They look great, were very easy to put down and do a superior job of delineating the roadway over marking tape.
If you have a catalog and price list of highway safety products I’d like to have a copy. Thank you.
