Long Lasting AASHTO M 249 Hot Melt Reflective Marking Paint for
Roads
Application Description
Hot melt reflective marking paint is mainly used for more than 2
level of the highway and highway, the marking coating thickness of
this paint is (1.0 ~ 2.5) mm, the paint is mixed with reflective
glass beads, and in the marking construction, the surface of the
reflective glass beads. This marking has good night reflective
performance, long service life, according to the traffic flow of
large highway construction of all kinds of road marking paint
demand estimates, small and the quality of the paint itself,
generally up to (2 ~ 3) years. The construction of hot melt coating
requires special heating equipment. For the second recoating of the
old marking line, the thicker old coating should be removed before
coating.
Construction Mode
Hot melt marking paint is solid powder at room temperature. During
construction, the paint is put into the melting kettle, and the
temperature in the kettle is controlled between 180 ° C and 210 °
C. While melting, it is stirred, and after melting, it is put into
the insulation melting hopper of the marking car. Melt coating then
back into the marking bucket, and heat preservation to keep the
material molten state. Before the line is marked by the pre-marking
machine position, according to the design drawing indicated on the
coating position with the lower coating machine primer. The marking
coating can be applied only after the coating agent dries
thoroughly. When the scribing begins, the scribing bucket should be
placed on the road, because there is a certain gap between the
scribing bucket and the ground, when the scribing car ahead, by
automatic flow and scrape out a neat line. The glass bead spreader
can automatically and evenly spread a layer of reflective glass
beads on the marking line.
