Colourbright is a new
reflective coloured surfacing. White light from
headlights is reflected back as coloured light
to the driver in the dark. This is made possible
through the development of Prismo's Clusterbead
technology.Colourbright is used primarily to give
warning of road hazards day and night, particularly
on unlit roads where standard coloured surfacing
is not easily visible at night. Prismo's Colourbright
has overcome this problem through the development
of Clusterbeads. Clusterbeads are powerful reflectors
embedded into the coloured surfacing.
For the first time, engineers can plan safety
schemes on unlit and poorly lit sites to provide
visual early warning for vehicles approaching
accident black spots, village gateways, cycle
paths and other high risk areas.
The process involves laying a polymer modified
bitumen scratch coat to level the area to be treated.
Pigmented epoxy resin is then applied, followed
by application of the Clusterbeads using a special
bead distributor. The resin is then dressed with
a pigmented resin-coated grit to provide skid
resistance.
At one trial site in England, accidents, including
fatalities and serious injuries, dropped from
ten in the previous two years to none over the
two year period following Colourbright installation.
Colourbright is available in red, yellow, green,
white and 'stealth' grey. |
