Lickman Interchange improvements: TrafficPatternsXD roundabout markings

The Lickman Interchange project included significant infrastructure improvements to the north and south portions of the interchange, with a key feature being a new two-lane roundabout at the Yale Road and Luckakuck Way intersection. We were engaged to supply and install the decorative pavement markings, TrafficPatternsXD™, as part of this broader road improvement project.

Roundabouts present a specific challenge for decorative pavement systems: the markings take concentrated turning and braking forces from vehicles working through the circular geometry. Standard thermoplastic or paint wears disproportionately fast in these zones.

TrafficPatternsXD at roundabout entries

We specified TrafficPatternsXD for the roundabout entry and crosswalk markings. The XD material is designed for exactly this use: higher abrasion resistance, a stronger bond to the asphalt substrate, and colour retention under the kind of repetitive stress that roundabout entry points generate.

The interchange also incorporates pedestrian crosswalk elements, where the decorative markings serve a dual purpose: improving visual definition of the crossing and contributing to the overall safety of the redesigned intersection.

The system

Square One installs TrafficPatternsXD beside StreetPrint® as the heavy-duty kind of stamped asphalt. The manufacturer describes it as an aggregate-reinforced preformed thermoplastic that is heated and stamped into the top layer of prepared asphalt, rather than laid on the surface. The sheets are 150 mil thick, against 125 mil for standard TrafficPatterns™, and the manufacturer's published point about wear is the one that matters at a roundabout: as the surface wears, new anti-skid elements are exposed rather than lost. It comes in the same patterns, borders and colours as TrafficPatterns, installs quickly with minimal traffic downtime, and the manufacturer positions it for major intersections, transit hubs and arterial crosswalks. The full specification is on the TrafficPatternsXD product page.

For an interchange or roundabout project

Projects like the Lickman Interchange are representative of a significant portion of our work: large municipal and provincial infrastructure upgrades where decorative pavement systems are specified as part of a broader safety and aesthetics package, rather than as standalone feature installations. A few things are worth settling early:

• Which surfaces carry the treatment. Truck aprons, splitter islands, speed tables and raised crossings all have to survive turning trucks and plow blades while telling drivers to slow down. Stamped asphalt and aggregate-reinforced thermoplastic both do that without the maintenance of pavers, and they read as part of the street rather than hardware bolted onto it. Our roundabouts and traffic calming gallery shows the range.
• The marking standard. TrafficPatterns and TrafficPatternsXD are made to the owner's marking standard, so colour and geometry follow the engineer's drawings, not a catalogue.
• Sequencing. The pattern goes into prepared asphalt, so the marking scope belongs in the paving schedule from the start rather than as an afterthought once the road is open.

We work with municipal engineering departments, general contractors and project managers on traffic improvement projects across the Lower Mainland and Fraser Valley.
