1. A process for forming a coherent refractory mass on the surface of a road comprising the steps of:
- mixing one or more non-combustible materials with one or more metallic combustible powders and an oxidizer;
igniting the mixture in a combustion chamber so that combustible particles react in an exothermic manner with the oxidizer inside the combustion chamber and release sufficient heat to form a high temperature coherent refractory mass under the action of the heat of combustion; and
projecting said high temperature mass from the combustion chamber onto the surface of the road so that the mass adheres durably to the surface of the road.

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.
