A roadway warning device including a portable rumble strip that includes high-density filler material to achieve a desired overall density and roadway stability of the rumble strip such as for use in high-speed traffic conditions without the use of conventional rigid metal ballast inserts. In some embodiments, the filler is dispersed and embedded within a flexible polymer composite matrix of the rumble strip body. In some embodiments, the filler is in the form of discrete unbound pieces of material disposed within a cavity of the rumble strip body. In some embodiments, the filler is in the form of a frangible article disposed within the rumble strip body.

A portable barricade includes at least three legs that are operably coupled together to permit movement relative to each other between a collapsed state and an expanded state. The barricade is configured such that when in the collapsed state, the at least three legs are arranged with at least one of the legs stacked between at least two other legs to form a compact stack that facilitates portability of the barricade. The at least three legs are operably coupled together for rotation about a common axis. When the barricade is deployed to the expanded state, each leg is rotated about the common axis to spread the legs apart such that each leg is arranged at a different angular position about the axis relative to the other legs, thereby enlarging the footprint and/or enhancing stability of the barricade.

VEHICLE-MOUNTABLE CARGO CARRIER FOR PORTABLE RUMBLE STRIPS
A cargo carrier for portable rumble strips that is mountable to a vehicle has a support surface that is configured to support multiple portable rumble strips. The support surface also is configured to move between a deployment position having a first width and a transit position having a second width that is less than the first width. The cargo carrier includes a frame that defines the support surface. In the illustrated embodiment, the support surface is divided along a major width dimension into at least three planar segments that are movable relative to one another to alter the overall width of the support surface, including a center portion and lateral portions extending from opposing sides of the center portion. The lateral portions are pivotably movable between extended positions aligned with the center portion in a horizontal orientation and retracted positions inclined relative to the center portion.
A portable roadway warning device comprises one or more rumble strips. Each rumble strip comprises at least two modular strip sections, each made of a polymeric material having top and bottom surfaces and end edges and side edges. At least one of the end edges of each of the strip sections has a plurality of aligned alternating notches and tabs, and connecting links hingedly connecting the tabs at one of the end edges of one of the strip sections to respective aligned tabs at one of the end edges of another of the strip sections. Each connecting link includes a Ushape link plate bracket and a pair of frangible rods that are configured to break at less than the tear strength of the polymeric modular strip sections.

A portable roadway warning device comprises one or more rumble strips. Each rumble strip comprises at least two interconnected strip sections, each made of a polymeric material. Opposite end edges of the strip sections have respective alternating notches and tabs sized and spaced for engagement with respective tabs and notches on opposite end edges of other of the strip sections to provide a releasable connected joint therebetween. The undersides of the tabs have transverse slots adjacent axial inner ends of the tabs for seated engagement by lower outer cross members extending transversely of the notches adjacent axial outer ends of the notches. The alternating notches and tabs in the respective opposite end edges of the strip sections are dovetailed for dovetailed engagement with one another.

A portable highway warning device includes any number of elongated rumble strips each fabricated of a suitable flexible polymeric material. Embedded within each rumble strip are a plurality of laterally spaced metal plates or bars to provide ballast to each rumble strip. The metal plates or bars run transversely across the width of each rumble strip with sufficient spacing therebetween to permit each rumble strip to be rolled up lengthwise from end to end when not in use.
