A portable speed bump disc which can be easily deployed and removed from the roadway to control the speed of traffic. The disc preferably does not require mechanical and or chemical attachment to the pavement, and a plurality of discs, when placed in a staggered array on the roadway, can improve the safety of crews working in flagging operations, traffic work zones, or other situations where daily installation and removal of roadway warning devices may be required. Each disc is relatively small and light in weight as compared to conventional elongated rumble strips or speed bumps, and can be handled and deployed by a single worker.

A road marking (10) has bristles (11) extending above a road surface level (12). The bristles (11) are attached below the road surface level (12), leaving a recess (13) between the road surface level (12) and the bristles (11). The recess (13) allows the bristles (11) to bend below the road surface level (12) during snowploughing. The forces exerted to the raised road marking (10) do not pull the bristles (11) or the whole road marking (10) assembly off the road surface.

The bristles (11) may be installed into the road surface by cutting a suitable cavity (15) into the road surface. A bottom portion of the cavity (15) is filled with a fluid adhesive, leaving the surface of the adhesive below the road surface. The bristles (11) are inserted in the fluid adhesive. After the adhesive has been cured, the bristles (11) stand proud from the road surface.

A speed bump section (10, 30, 50; 110, 130, 150) is provided for use in a modular speed bump. The speed bump section comprises an end configured to engage with another speed bump section. The end is one of (i) a male end (16, 36; 116, 136) having a first plurality of angled sides, and a male connector (20, 38; 120, 138) having a corresponding first plurality of angled sides; and (ii) a female end (18, 56; 118, 156) having a second plurality of angled sides configured to receive a said male end, and a female connector (22, 58; 122, 158) having a corresponding second plurality of angled sides configured to engage with a said male connector. A modular speed bump comprising a plurality of speed bump sections is also provided.

A preformed thermoplastic roadway line marking includes a preformed thermoplastic substrate layer capable of being attached to a roadway, and a preformed thermoplastic upper layer in contact with the substrate layer. Advantageously, such an upper layer includes a surface area having a plurality of spaced-apart slits. The slits penetrate through an entire cross-sectional thickness of the upper layer and are in fluid communication with the substrate layer. When heated to a liquid state, the substrate layer has a morphed shape and is at least partially displaced upwardly through the slits and disposed on the upper layer such that the upper layer is fixedly locked to the substrate layer and maintained at a substantially stable position relative to the substrate layer. Such a structural configuration provides an unexpected and unpredictable result of insuring the marking is locked into place relative to the roadway, thereby reducing labor costs and improving durability.

A device to slow down and/or stop means of transport on pavement, in particular a road pavement. The device includes a series of lamellar elements substantially parallel to each other, and provided with upper edges protruding from the upper part of the pavement, or substantially flush with the pavement.
