SOIL COMPACTOR FOR COMPACTING SOIL MATERIAL AND METHOD FOR OPERATING SUCH A SOIL COMPACTOR
A soil compactor for compacting soil material, in particular asphalt, comprises at least one compactor roller (14, 16) which is rotatable on a compactor structure (30) around a roller axis of rotation (W) which is essentially orthogonal to a compactor longitudinal direction (L) and at least one marking unit (26, 26) carried on the compactor structure (30) for applying marking material (M) to soil material (12) driven over by the soil compactor (10).
TAPE MACHINE
An improved automated tape applicator that applies pavement marking tape to a pavement surface. The automated tape applicator may include dual knives for cutting two or more patterns simultaneously, a hinged frame that permits an adhesion roller to be lifted off the ground when not in active use, an electronic clutch for selectively engaging a tape feed mechanism, a swiveling front tire, an automated controller for simultaneous application of multiple markings and accurate dimensioning, and/or replaceable knife inserts.

Groove monitoring system for roadway markings
Systems and method for applying roadway marking materials into a groove(s) in a roadway surface and/or forming a recessed groove(s) in a roadway surface. The systems and methods incorporate a contour sensor that provides real-time information of the marking material and/or groove. Based on the contour information, a marking material applicator can be aligned with a recessed groove in a roadway surface to ensure the marking material is applied within the confines of the groove. Alternatively, such contour information may be acquired during groove formation to ensure depth, tilt and/or bottom surface smoothness of the groove is within predetermined limits.
DEVICE FOR REMOVING ROAD TAPE
A device for removing road tape from a surface comprises a body, and a drive assembly coupled to the body. The drive assembly comprises a motor having a drive wheel, at least one drive belt, a rolling drum drive wheel configured to engage the at least one drive belt, and at least one rolling drum configured to secure an end of the road tape. The rolling drum is configured to rotate in response to rotation of the rolling drum drive wheel and wind the road tape about a circumference. The winding of the road tape drives the body in a forward direction.
ROAD TAPING MACHINE
A road taping machine is configured to unspool road marking tape from a spool and tamp that tape onto pavement via a tamping roller. Tape is cut using a blade assembly, and aligned with several alignment rollers. A pivot arm permits a subset of the alignment rollers to displace, allowing slack in the tape to be taken in during cutting such that taping can occur continuously, despite cuts. The spool is housed on an axle anchored to a support arm that can be actuated between an elevated position for loading, and a depressed position for taping. A taping section of the machine is laterally displaceable relative to a drive section via a displacement plate, to permit taping of laterally remote locations. The machine can support multiple spools, including spools with tape paths that bypass the blade assembly.
Anisotropic retroreflective mesh for longitudinal pavement marking articles and methods
In various embodiments, the present disclosure provides for reflective materials, articles and methods incorporating a mesh arrangement of multiple, discrete retroreflective canted cube corner reflectors each having generally flat incident surfaces and high transparency, with a geometry and a refractive index ratio sufficiently high enough to produce a high degree of total internal reflection (TIR) that results in anisotropic retroreflectivity.
GROOVE MONITORING SYSTEM FOR ROADWAY MARKINGS
Systems and method for applying roadway marking materials into a groove(s) in a roadway surface and/or forming a recessed groove(s) in a roadway surface. The systems and methods incorporate a contour sensor that provides real-time information of the marking material and/or groove. Based on the contour information, a marking material applicator can be aligned with a recessed groove in a roadway surface to ensure the marking material is applied within the confines of the groove. Alternatively, such contour information may be acquired during groove formation to ensure depth, tilt and/or bottom surface smoothness of the groove is within predetermined limits.

Apparatus and method for creating a musical road
An apparatus 10 and method is disclosed for creating one or more notes as a car 14 drives over the apparatus 10 on a road surface 12. The apparatus 10 can include a first strip 16 of durable material having a length 58 and a width 52; and a first plurality of recesses 20 defined in the first strip 16, each of the first plurality of recesses 20 extending across a portion of the width 52 of the first strip 16; wherein the first plurality of recesses 20 are spaced along the length 58 of the first strip 16 a first distance 24 from one another, the first plurality of recesses 20 producing a first note when the first strip 16 is placed on the road surface 12 and the car 14 drives over the length 58 of the first strip 16.
