Description
A roll of MagmaLine R105, a thermoplastic road marking used to lay permanent yellow lines onto asphalt surfaces. This preformed sheet material is made from a combination of resin, pigments, additives, fillers and glass beads (for reflectivity). To install, the road surface first needs to be cleaned and then pre-heated using a gas torch to remove any moisture. The line is cut to size and placed in position, the top film removed and the line then heated with the torch in an even sweeping motion. As the heat increases, the line will begin to melt and shrink into the profiles of the road surface and the edges will bevel off until the plastics are fully bonded. Easily laid without the need for specialist boilers or complicated equipment, this road marking is durable (expected lifespan of around 5 years), meets Highway standards, can be trafficked very quickly to minimise road closure times and is an economic way of re-instating short runs. The thickness of the material can also produce vibration and sound when being driven over, providing a warning to road users. Thermoplastic road marking materials were first developed and patented in the UK in the 1930s and are most commonly applied as a thin layer of paint, but this typically wears out quickly, losing contrast and retroreflective properties.
