1. Apparatus for forming a coherent refractory mass on the surface of a road, the apparatus comprising:
- a combustion chamber adapted to be disposed on a surface of a road;
a container for holding metallic combustible powder(s) and non-combustible ceramic powder(s);
a first supply line for transporting one or more metallic combustible powders, one or more non-combustible powders and an oxidizer to the combustion chamber;
a second supply line for supplying air to the combustion chamber to supply additional oxygen, to assist in projecting the refractory mass from the combustion chamber and for cooling the inside of the combustion chamber; and
an igniter associated with the combustion chamber and operative to ignite the mixture of combustible powder, non-combustible material and oxidizer in the combustion chamber to cause the metallic combustible powder to react in an exothermic manner with the oxygen and release sufficient heat to form a refractory mass which is projected against the surface of the road so that the mass adheres durable to the road surface.

Abstract
A process and apparatus for forming a coherent refractory mass on the surface of a road wherein one or more non-combustible materials are mixed with one or more metallic combustible powders and an oxidizer, igniting the mixture so that the combustible metallic particles react in an exothermic manner with the oxidizer and release sufficient heat to form a coherent mass under the action of the heat of combustion and projecting this mass against the surface of the road so that the mass adheres durably to the surface of the road. The combustion chamber can be operative with a reverse vortex to cool the walls of the chamber.

49. Apparatus for forming a coherent refractory mass on a surface of a road, the apparatus comprising:
-
a combustion chamber adapted to be disposed on a surface of a road;
a container for holding metallic combustible powder(s) and non-combustible ceramic powder(s);
a single supply line for transporting one or more metallic combustible powders, one or more non-combustible powders and an oxidizer to the combustion chamber; and
an igniter associated with the combustion chamber and operative to ignite the mixture of combustible powder, non-combustible powder and oxidizer in the combustion chamber to cause the metallic combustible powder to react in an exothermic manner with the oxidizer and release sufficient heat to form a refractory mass which is projected against the surface of the road so that the mass adheres durable to the road surface. - View Dependent Claims (50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82)
