Pavement markings service life in roundabouts

How to increase the service life of pavement markings installed in roundabouts

pavement markings

Pavement markings don’t perform well in these very high tire-shearing roundabout locations. In fact, the rate of pavement marking failures are significantly greater there than in any other pavement location.

To get markings to last longer, SMITH has designed surface-preparation techniques of adding an SP3 – 6 surface profile prior to installing the pavement marking. The profile provides a stronger mechanical bond with the newly applied markings to withstand transitional traffic shearing.

Without a profile, markings applied on smooth surfaces simply break free after a short time. For more information on surface profiling, please check out our article on the subject.
