The invention relates to an environment-friendly road surface ice and snow melt coating material, a preparation method thereof and a using method thereof. Serious consequences such as traffic jam and the like can be caused by snow accumulation in winter; and at present, a snow removal method comprises passive snow removal and active snow removal, wherein in the passive snow removal, the operating efficiency of manual snow removal is low, mechanical snow removal is incomplete relatively in clearing, and for the spreading of a snow melt agent, substances with the snow melt effect are mixed simply only, so the spreading is non-uniform, and the snow melt agent dispersed to peripheral air has the major influence on environment; and the active snow removal is high in cost, and has a certain damage to structures of road surfaces, so the service life of roads is shortened. In the environment-friendly road surface ice and snow melt coating material, after being loaded on a carrier material, the snow melt substances are mixed with emulsified asphalt, water-soluble epoxy resin and a curing agent and sprayed on the road surfaces to form an ice and snow melt coating, so that the roads have the function of melting snow actively. By the environment-friendly road surface ice and snow melt coating material, an ice point of water is reduced to between -5 and -20 DEG C so as to clear the ice and snow of the roads, and the coating material has the sustained-release function, is high in coating adhesivity and wear-resisting effect, low in cost and convenient to maintain, and can prolong the life of the road surfaces effectively.

An apparatus for locating, inspecting, or placing marks on a roadway. The apparatus includes a GPS-based machine vision locator for sampling discrete geographical location data of a pre-existing roadway mark evident on the roadway. A computer may determine a continuous smooth geographical location function fitted to the sampled geographical location data. A marker is responsive to the GPS-based locator and geographical location function for replicating automatically the pre-existing roadway mark onto the roadway. The apparatus is typically part of a moving vehicle. A related method is disclosed for locating, inspecting, and placing marks on a resurfaced roadway. A similar apparatus can be used to guide a vehicle having a snow plow along a snow-covered roadway, or a paving machine along an unpaved roadway surface.

A snowplow mount is provided wherein a vehicle mount extending from the plowing vehicle is affixed to a reversing table, which is in turn rotatably connected to a plow moldboard at one or more pivots. One of the moldboard or the reversing table includes a bearing thereon, the bearing having a bearing bore defined therein. The other of the moldboard or the reversing table includes a pin which is elastically journalled within the bearing so that the pin and bearing may both rotate with respect to each other as well as translate with respect to each other in radial directions (i.e., in planes which are generally parallel to the axes of the pin and the bearing bore). Thus, loading of the moldboard allows the moldboard to translate with respect to the reversing table at the pivot as well as rotate. The reversing table is rotatably affixed to the vehicle mount with a linear actuator affixed therebetween so that actuation of the linear actuator will cause the reversing table to rotate with respect to the vehicle mount. The linear actuator is elastically mounted between the reversing table and vehicle mount so that the two may rotate a slight amount with respect to each other, with such rotation being elastically resisted. As a result, shock loading of the moldboard (and thus the reversing table) will not be readily transmitted to the linear actuator.

In a first embodiment, a motor connected to the arm rotates a flap connected thereto to raise the blade above the windshield. In a second embodiment, a cover for a casing attached to the windshield is raised into an idle deployment configuration for engaging the arm and raising the blade above the windshield. In a third embodiment, a body on the arm has a pivoting member to engage an engagement stop on the windshield, with the pivoting member pivoting into a vertical configuration to lift the blade off the windshield.

This method provides various high-power-ratio snow removal devices which clear paths narrower than the motor vehicles. We use small, light, low-priced, yet also safe, durable devices to clear the narrow swaths. High power ratios result from applying motor vehicle horsepower to small snow removal devices similar to those found on lawn tractors. Such devices may comprise moldboard plows (FIGS. 3, 9, 10, 11, 15, 16), snow throwers (FIGS. 7 and 13), or combinations of both types (FIG. 12 and 17). Quick-connect and quick-release fittings (FIGS. 3A, 3B, 6, 8, 9A, 9B, 14) position each device for temporary propulsion by a vehicle. The connectors allow quick conversion of the family car to a plowing machine, and when plowing is done, quick re-conversion. A moldboard plow of about half the car's width (FIG. 3) is our preferred embodiment. The mini-moldboard (FIG. 10) is least expensive. Deepest snow can be handled by our tall, narrow moldboard (FIG. 15). We protect homeowners, their cars and their plows from injury when plows strike hidden objects. Protection devices comprise safety springs (60) and pivots (63, 67 and 69) of FIG. 3B, the tension-release mechanism mentioned but not detailed in FIG. 15, annor shields (396, 398) of FIG. 16 and various others mentioned or provided for in our drawings but not detailed. We prefer cars' chassis tie-down ears (72) in FIG. 3A, as connector points for our plow or thrower arms. For cars lacking such ears, we propose add-on ears. For example, tie-down ear (126) in FIG. 6.
