    Abstract: A snow removal vehicle is provided as a means of collecting, melting, and transporting in order to facilitate snow removal operations during winter months. The snow removal vehicle is able to remove and dispose of snow from a plurality of environments. The snow removal vehicle accomplishes this through the user of a snow collection means mounted to the front section of an existing vehicle. The snow collection means channels removed snow through a snow conveyance means which transports the collected snow to a water tank positioned within an insulated enclosure. A high pressure nozzle sprays the collected snow while in the snow conveyance means to melt it before it reaches the water tank. The water tank contains the collected snow as water, but additional serves as reservoir for the high pressure nozzle.

    Abstract: The invention is a portable ground thawing device using a shallow rectangularly shaped box-like apparatus (or thaw body) that is open-ended on the side that would normally form the floor of the thaw body. This open-ended box is constructed with a high degree of insulating value and is designed to trap heat against the surface of frozen ground while also including a reflective inner surface. The heating requirements are supplied by the use of an externally mounted radiant propane heater that is commonly available in the marketplace today. This attachment is built into one of the short vertical walls on the end of the thaw body by placing the burner element of the radiant heater in the most outward opening of a vented heat transfer tube. The vented heat transfer tube is a cylindrical opening that passes from the outside of the thaw body so as to leave an air gap to allow for the free flow of air from inside the thaw body to the outside by the burner.

    Abstract: A method for laying a snow road or an airplane runway on a snow or ice covered surface includes the removal of a predetermined and relatively small portion of the snow or ice surface, which is melted to water and mixed with the snow or ice remaining on the snow surface. The mixture of water and snow or ice is leveled so as to form a road surface when the mixture freezes. Preferably, the snow remaining on the surface is mechanically worked with a rototiller, while the melted snow is injected into the snow being worked. The method is particularly advantageous in that it can be carried out without requiring melting of all the snow necessary to form the snow road, or requiring the addition of any water from an external source, other than the portion of snow removed from the snow surface.
