Highway Marking Tape

The modern highway is the stretch of pavement that experiences the highest volume of vehicle traffic, with automobiles and trucks careening along at a breakneck pace, heaping relentless abuse on the road markings beneath their wheels. Like any other road, highways also need delineating lines to guide drivers, but most materials used to mark regular streets may not endure the rather heavy traffic volume encountered on a highway. Paint fades, cracks and gets worn away in a matter of weeks. Regular pavement tape is either ripped off or deteriorates quickly. To withstand highway levels of vehicle activity, the marking device must be manufactured to be extremely durable, without compromising other basic attributes like reflectivity and flexibility. Responding to this fundamental requirement, manufacturers of pavement tape now produce and distribute a grade of highway marking tape that is built to last, combining unparalleled polymer strength with excellent functionality.

The top layer of highway marking tape is composed of a highly reflective pigment, normally white and yellow, which yield the best results when subjected to automobile headlights. To enhance reflectivity further, this layer is embedded with glass beads to capture and diffuse reflected light. This is a standard feature even of low-grade tapes, however, so the premium quality of highway tape lies in its central layers, which are responsible for its vaunted durability. The highest classes of highway tape are made from relatively thick polymerized compounds, which may be reinforced with aluminium lining or blended in such a manner that allows them to absorb pressure without breaking or ripping. Adverse weather conditions, particularly those involving moisture accumulation or extreme temperatures, are tolerated well by this formidable grade of tape, as opposed to weaker series, whose lifespan can be significantly shortened by a cold spell. masking tape manufacturer

The last component of a good strip of highway tape is the adhesive portion, which is pre-coated and pressure-sensitive, firmly gripping the concrete or asphalt upon which it is applied. Once it has been tamped down, the tape will permanently adhere to the surface of the highway, and do so without any deterioration in its performance for a period of at least 36 months.

Installing highway tape properly typically involves an overlay method, in which the area is first swept clear of debris and dirt that may interfere with the bonding of the tape to the surface. Liquid waste, such as spilled oil or grease, is also wiped away from the intended taping points. Afterwards, the tape is laid down, and then tamped into place, preferably with a tamping device that supports a load of at least 200 lbs. and is at least 2″ wider than the width of the tape that is selected. One would be wise to use butt splices during the tape laying, and although a primer is not indispensable to the functioning of the tape adhesive, it would not hurt to reinforce the tape further if you have the budget for it. It must be noted that the preferred ambient temperature for installation should be at least 40 degrees F (5 degrees C) or above, or any manufacturer guarantee as to the lifespan of the highway tape may be negated.
