SCREED GRADE
Consists of a heated hopper mounted on a pram, which feeds hot molten thermoplastic under gravity to a rectangular screed with a gate at the base. The gate opening is set to produce the thickness specified for the hot thermoplastic as it flows onto the pavement. Where immediate reflectivity is required, a manually operated Glass Beads dispenser should be attached to the screed applicator. For letters, numerals and hatched areas, a hand-held mould box is filled manually using a bucket. Glass Beads are then applied by hand. Generally used for Stop Lines, Pedestrian Crossings, Letters, Arrows and Double Yellow Lines.
This process employs a self propelled application pram. The Screed process utilises gravity to screed the hot thermoplastic through a gate opening set to produce a line of pre-selected thickness of material onto the road surface. Glass Beads are gravity applied to the molten line. For more details refer to our Thermoplastic Screed Method Statement.
Recommended Thickness 2 .0 – 4.25 mm.
A low output marking for traffic delineation, advisory markings and mandatory markings in urban areas where space is limited and for small sites where it is impractical to use truck mounted application equipment.
