The invention herein pertains to pavement marking patterns and the application thereof to roads, streets, walkways and the like. Various pattern designs for the markings are available to replicate layers of bricks, cobblestones, horizontal signage, logos and other components. The marking patterns are composed of two or more independent sections. The first section is a grid representing for example, the mortar joints in a brick wall. The second sections or inserts, for example represent bricks which are contained within the grid. As the first and second sections are generally formed from different colored, preferably thermoplastic materials, a hot melt adhesive spray is utilized on the bottom surface of the marking pattern to bridge the intersections between the first and second sections to maintain the integrity of the marking pattern for convenience during handling and application to a substrate.

A control system for positioning a marker over a pre-existing roadway surface mark. The control system has an electromagnetic radiation source attached to the marker for producing a mark pattern on the roadway surface. An imager permits the control system to image both the pre-existing roadway surface mark and the mark pattern produced by the electromagnetic radiation source. A computer is responsive to the imager for producing an error signal based upon the location difference between (a) the image of the pre-existing roadway surface mark and (b) the image of the mark pattern produced by the electromagnetic radiation source. An actuator is responsive to the error signal for positioning the marker over the pre-existing roadway mark.

A rotary mill for grinding recycled glass materials into particles has a housing defining an impact chamber with a rotor in the chamber at the bottom of an inclined guide wall underneath the feed opening. The rotor has a plurality of axially extending, angularly spaced massive impact hammers so that the impact hammers impact and deflect the solid materials onto a plurality of shatter bars located at the peripheral wall. Each of the impact hammers has a leading blade element of a hardened steel which has a front face inclined relative to a bottom portion of the guide surface so that an outer edge of the front face is angularly advanced relative to an inner edge thereof.

A pavement marker is disclosed that includes a base member, two opposite resilient members and an upright member, wherein the upright member has an ends that extend laterally from a central section and are received into the opposite resilient members and wherein the base member is substantially planar with side rails, extends under the upright member and is adapted to receive and retain the resilient members. The resilient members hold the upright member in an upright position and allow for rotation of said upright member in response to a force applied to the upright member wherein the central section of the upright member includes a reflective surface.

Provided are an installing method for efficiently installing a magnetic marker and a work vehicle. In a magnetic marker installing method for installing a magnetic marker to be laid on a road so as to be detectable by a magnetic sensor attached to a vehicle in order to achieve vehicle-side control to achieve assist in driving operation of the vehicle by a driver or automatic driving not relying on operation of the driver, a placing process P103 of placing the magnetic marker before magnetization on the road and a magnetizing process P106 of magnetizing the magnetic marker placed on the road by acting on the magnetic marker with a magnetic field are performed.
