- Slurry seal
- A cold-applied mixture of emulsified asphalt, fine aggregate, mineral filler and water that is squeegeed over worn pavement as a thin wearing surface. It seals small cracks and restores texture, but its mix design and ground temperature limits matter, and covers and collars must be protected.
- Fog seal
- A very light spray of diluted asphalt emulsion over an existing surface to renew its look, bind loose fines and slow oxidation. It is also used on freshly ground areas after marking removal, and too heavy a coat leaves a slick surface.
- Alligator cracking
- A network of interconnected cracks shaped like reptile skin, caused by fatigue of the surface under repeated loading, usually from a weak base or poor drainage. Sealing the surface will not cure it; the failed area must be removed and the base repaired.
- Thermoplastic striping
- A marking material supplied as solid resin that is melted and applied hot, either extruded or sprayed, then cools into a durable film. It needs a primer on most surfaces, application temperatures within a defined range, and a minimum film thickness to perform.
- Methyl methacrylate
- A two-component reactive marking material that cures chemically and bonds firmly to asphalt and concrete. It lasts longer than paint, is applied within a wide temperature range, and is chosen where wear from traffic is heavy.
- Waterborne traffic paint
- A water-based striping and marking paint that dries by evaporation and coalescence. It must go on clean, dry pavement and must not be thinned, and rain, fog or a falling temperature before it dries can ruin the line.
- Glass beads
- Tiny glass spheres dropped into wet paint or hot thermoplastic and embedded about halfway so they reflect headlight beams back to the driver. Their application rate per gallon of paint is a standard quantity, and missing or buried beads make a stripe invisible at night.
- Retroreflectivity
- The property of a marking that sends light back toward its source, measured in millicandelas per square meter per lux. Specifications set minimum readings by material and color, so a line can fail acceptance even when it looks fine in daylight.
- Raised pavement marker
- A small reflective or non-reflective button bonded to the road surface to supplement or substitute for painted lines. It is placed on a layout, bedded in adhesive, and removed with the stripe it belonged to when the traffic pattern changes.
- Wheel stop
- A precast or recycled-material block anchored to the pavement at the head of a stall to keep a vehicle from rolling forward into a walkway, wall or accessible route. Placement depends on the stall depth and the clear width needed beyond it.
- Access aisle
- The striped space beside an accessible stall that lets a driver or passenger deploy a ramp or lift and move out of the vehicle. It is outlined and hatched, marked against parking, shares the stall's level surface, and must meet minimum width.
- International Symbol of Accessibility
- The white figure on a blue field that identifies accessible stalls, routes and signs. Its minimum size and position relative to the stall centerline are fixed, and reflectorized signs carrying it must be mounted at a minimum height.
- Fire lane
- A marked access route that must stay clear so fire apparatus can reach a building. It has minimum width and headroom, is identified by curb paint or signs with required wording, and cannot hold calming devices that slow or block fire trucks.
- Taper
- The sloped line of channelizing devices that guides traffic gradually out of a closed lane. Its length depends on lane width and speed, and cutting it short forces abrupt merging that endangers both drivers and workers.
- Channelizing device
- A cone, drum, tubular marker or barricade used to direct traffic around a work area. Choice and spacing vary with speed and duration, and on striping jobs these devices travel with the moving operation.
- Flagger
- A trained worker who controls traffic through a work zone with a paddle or flags, from a position visible to approaching drivers. The station needs advance warning signs, good sight distance and a safe retreat path.
- Underground Service Alert ticket
- The request number issued by the regional one-call center before ground is broken, such as for sign posts or bollards. It starts a waiting period so utility owners can mark their lines, and the markings must be respected and the ticket kept current.
- Touchdown and liftoff area
- The load-bearing surface on a heliport where a helicopter lands or departs. Its markings, such as the outline, the H symbol and perimeter lines, follow aviation standards rather than ordinary parking conventions.
- Acrylic court coating
- A pigmented, sand-filled acrylic system rolled or squeegeed over asphalt or concrete to give game courts a uniform, cushioned playing surface. Layers are applied in sequence, then court lines are taped and painted to exact dimensions.
