ABSTRACT OF THE DISCLOSURE
A metal producing patch material for filling chuck holes in pavements
consists of a mixture comprising between about 10% and 20% pitch, between
about 20% and 25% refractory particles, and exothermic materials which
comprise between about 37% and 60% iron scale and between about 10% and
18% aluminum particles, the iron scale and aluminum particles being
present in amounts sufficient to form an exothermic reaction when ignited
to melt the iron in the scale and form a molten liquid which includes the
refractory particles therein. This invention distinguishes from others by
reason of the inclusion of iron scale in amounts greater than needed for
the exothermic reaction with the aluminum particles, so as to result in
a metal producing material.
