Appeal No.1997-2277
Application 08/462,814
This is an appeal under 35 U.S.C. § 134 from the final rejection of claims 1 through
8, all the claims pending in the application.
Claim 1 is illustrative of the subject matter on appeal and reads as follows:
1. An asphaltic concrete compound for either as a top layer of paving, or at least
the first bottom layer of a pavement patch and then the top layer of a pavement patch, to
efficiently intercept microwave energy whenever directed downwardly to the top layer of
paving, or to the first bottom layer of a pavement patch and then to the top layer of a
pavement patch, to generate heat in these respective layers, so the generated heat will be
efficiently conducted essentially to the surface of these top layers, to debond ice which had
previously bonded to the surface of these layers, for the purpose of readily removing the
debonded ice from paving, and in respect to pavement patches, when necessary, readily
removing the debonded ice, while also heating the surfaces of the pavement hole to aid in
the bonding of the asphaltic concrete compound used in filling the pavement hole,
comprising:
aggregate, comprising gravel, rocks, and the added lossy microwave anthracite
material; and
asphalt cement surrounding the aggregate;
whereby, the added lossy microwave anthracite material is included in a quantity
large enough to efficiently intercept microwave energy, which is directed downwardly to the
surfaces of this asphaltic concrete compound (emphasis added).
