Abstract: A multi-sided wheel to replace one of the wheels of an existing cold milling machine. The wheel has a series of flat surfaces in spaced relationship. The flat surfaces allow the machine to drop its cutting drum relative to the surface over which the machine is traveling to cut a rumble strip. As the wheel rotates, it will support the machine on one of the points formed by the confluence of two adjacent flat surfaces, thereby raising the machine and causing it to raise its cutting drum out of the rumble strip that it has just cut. Because the flat surfaces are spaced apart, the cutting drum will be moved forward in a looping fashion as the wheel rotates before the wheel drops onto the next flat surface to lower the cutting drum for cutting the next, spaced rumble strip. Thus, the multi-sided wheel causes the machine to move up and down as it propels along its path of travel. A pentagonal wheel is the optimal design for use in conjunction with a Wirtgen.RTM. W500.TM.

Abstract: In the method for applying horizontal markings to road surfaces, a water-thinnable emulsion paint which is acid-coagulable is used and is brought into contact with an acid. This acid is scattered or sprayed onto or into the sprayed paint, the acid being in the form of an aqueous solution, a powder or particles wetted with acid. The method brings about drying within one or a few minutes. Using road-marking vehicles, horizontal markings can thus be put down with virtually no closing-off of the mobile operations site.

Abstract: A method and apparatus for controlling striping equipment mounted on a vehicle includes a controller. The controller receives signals from a distance measuring device and various sensors. The controller also receives operator input via a console having operator controls. Based on the operator input, the controller determines striping commands which instruct the controller to cause the striping equipment to paint a painting pattern. The controller generates a striping program during a striping operation by saving the striping commands as a function of the measured distance. Using a previously saved striping program, the controller can cause the repainting of a previous striping operation. The controller also monitors striping operational data as a function of the distance travelled, and performs diagnostic functions to determine malfunction of the striping control system and the controller itself.

Abstract: A method and apparatus for marking a surface with a predetermined pattern is described. The apparatus includes a surface marking mechanism that supports a material dispenser. The material dispenser is manipulated along a number of axes including an x-axis, a y-axis, and a z-axis. In addition, the material dispenser is manipulated to rotate around a w-axis and to form a tilt angle with the w-axis. The surface marking mechanism includes movement devices for initial positioning of the mechanism and for re-positioning the mechanism to complete a selected pattern that does not fit within the border of the mechanism. The surface marking mechanism is responsive to control signals from a controller. The control signals are derived from a mathematical model characterizing the spatial relationship between the predetermined pattern, the material dispenser, and the surface to be marked.

Abstract: The use of impact force to cause an impression to be transferred to an asphalt road surface in a repetitive manner to form a series of depressions. The use of hydraulic, pneumatic and gravity drop as power sources are discussed. Imprint plates having single impression or a plurality of impressions are disclosed. Various shapes for the resulting depressions are explained including a shape that matches current milled depressions. Several methods of installing the series are discussed including stationary stamping, where the machine is paused during stamping, continuous stamping and continuous machine movement with imprint plate pause relative to the surface under treatment. The latter discloses a methodology wherein the imprint plate is transferred rearward on the transport vehicle at a pace equal to the advance of the transport vehicle. Various gauging means are explained to ensure that the resulting depressions are within predetermined parameters which prevent overstamping and understamping.

Abstract: The use of a cam member having a plurality of camming groups to cause a raising and lowering motion to be transferred to a cutting head to install a series of SNAP depressions in the surface of an asphalt road. Two cutting methods are disclosed, the first allowing cutting through the cut, the second allowing a near plunge cut to be made. Cutting through the cut permits a smaller diameter cutting drum than would fit the resulting cut while providing for a smooth action to the cutting procedure. A near plunge cut permits adaptation of existing equipment utilizing current use cutting drum which diameter approximate the shape of the resulting cut. Proper spacing is ensured by having the cam member in direct communication with the surface under treatment with movement provided by the installing machine. The optional adaptation of a skip pattern within the series is taught.

Abstract: A machine and method of use to form Sonic Noise Alert Pattern (SNAP) type depressions in the surface of an asphalt road in a series to line the edge or center of a road. The machine installs a plurality of depressions in a group during a single cutting procedure. A repetition of these cutting procedures results in the desired series being formed. The machine has a single rotary type milling head with spaced sets of bits which will engage the surface of the road. Only where the spaced sets contact the surface will the cutting action be performed. From a stationary position an initial plunge cut brings the rotary cutting head in contact with the surface. Then a lateral movement of the rotary cutting head results in elongating and forming the desired sized depressions. Then the rotary cutting head is raised, the machine is advanced and the prior steps are repeated in repetition until the desired number of depressions have been formed.

Abstract: The mechanical device used for carrying out the procedure consists of a reel (B), upon which is wound a conveyor sheet. Before the sheet is wound onto the said reel, the retroreflecting elements (A) are attached to it, maintaining a certain preestablished spacing between the elements.

Abstract: An apparatus and method for cutting grooves on the edges of an already formed road. Each of a plurality of toothed cutting wheels revolves about a substantially vertical driving shaft. Simultaneously, each cutting wheel (attached to a respective rotary shaft) revolves about its own longitudinal and substantially horizontal axis. The apparatus is moved along a road, near an edge thereof, thus giving rise to one linear motion and two rotary motions. Sequentially, each cutting wheel enters an edge of the road from a region beyond the road edge, due to a slight tilt of the plane which contains the cutting wheel rotary shafts. The resultant grooves are deepest at the road edges and then gradually diminish to zero depth, the grooves being arcuate and parallel to each other. With the plane containing the cutting wheel shafts completely horizontal, the apparatus can cut rain drainage grooves in a raised marking strip on the road or can remove bumps from the road.

Abstract: This invention concerns a process for making a roadway marking strip adhere to a roadway surface without the need for any preliminary preparation, using a flame that simultaneously contacts the self-adhesive primer coating of the roadway strip and the roadway surface itself.

Abstract: An apparatus and method for cutting rain drainage grooves in a road surface, such as at the edges of the road to form a road marker system. A cutting cylinder rotates about its longitudinal axis, the latter lying in a substantially horizontal plane and at some angle, generally a right angle, to the road direction. The cutting cylinder is mounted on a frame, the latter attached to and carried by an automotive vehicle such as a truck. As the truck travels along the road, the cutting cylinder is moved alternately up and down, into the road surface, and forms the grooves. The cutting cylinder can be slightly tilted, so as to produce grooves of variable width and depth. The truck moves along the road being grooved at a substantially uniform speed. Preferably, the slopping side walls of the grooves are coated with a retro reflective coating. The grooves continuously drain rain so that the retro reflective coating is visible during hours of darkness and rain, to maintain visibility of the road edge to drivers.
