3 Pavement Markings Removal Methods

Pavement markings are designed to provide crucial information to drivers as well as pedestrians on road usage. This guidance is aimed at improving safety on the roads, walking pavements and even parking spaces. For instance, the markings promote responsible usage of roadways by indicating safe zones for overtaking and setting apart an area for walking. There are different types of pavement marking materials used in commercial properties including paint, epoxy, tape and special thermoplastics.

These markings fade out with time or become unsuitable as the buildings and general surroundings are modified. As the property owner, you should understand different removal techniques. This will help you choose the ideal method for removing obsolete pavement markings in preparation for new ones.

Water Blasting

This technique is also known as hydroblasting or water jetting and as implied, it utilises water. The removal equipment systems are designed to produce water at ultra-high pressure and the stream is directed to the markings. This technique can remove sealers, curing compounds and paint linings. It is fast and highly efficient especially on concrete and asphalt surfaces.

You should consider using this method for your project because chemicals and abrasives are not used. This means that there will be no negative environmental repercussions and the pavement will not sustain significant damage. Furthermore, it is relatively inexpensive since you will only pay for labour and equipment hire.

Compressed Air Thermal Lance

The compressed air lance technique is primarily used on thermoplastic pavement markings. Generally, a mixture of compressed air and propane gas is used to produce a powerful flame at high velocity. The heat will vaporise the layers of the road line markings. The temperature of the flame is extremely high so this method can damage your pavement. Moreover, the method will produce smoke, noise and noxious fumes so it is not appropriate for densely populated areas. You should discuss the suitability of the method for your property with contractors like Pelican Linemarking.

Mechanical Scabbling

Mechanical scabbling is a removal method that cuts and grinds the pavement markings. It is achieved by motorised steel or tungsten cutters rotating at high speeds. The quality of the results achieved through this process will depend on the pressure and depth settings in the equipment. Complete removal of the markings cannot be achieved without cutting deep into the roadway surface. This will damage the property and you will be charged substantial debris removal fees. This technique is suitable for partial removal of the markings in preparation for new ones.
