Asphaltic concrete compounds comprised of asphalt cement and aggregate have, as a substantial portion of their respective aggregates, anthracite coal particles and fines, which are added specially as a lossy microwave material. These asphaltic concrete compounds are particularly useful when laid down as a pavement, or a top layer of a pavement, which thereafter can be freed of ice, by using microwave energy to debond the ice. The debonding of the ice occurs without causing any noticeable melting of the ice, and the debonded ice is thereafter easily lifted and removed from the pavement of the way, serving as a roadway, highway, runway, or walkway. Also these asphaltic concrete compounds are particularly useful as patching materials when damaged pavement is being repaired, especially during cold weather. They are used to coat the damaged pavement portions, creating a coating, to thereafter receive microwave energy, which results in the penetration of heat into both the coating and the portions of the damaged pavement. This heat insures their bond, and also the bond of the asphaltic concrete compound, which is filled into the damaged pavement cavities. Also the top layer and/or the entire filled cavities of the originally damaged pavement, include this asphaltic concrete compound, which has the anthracite coal, added as the lossy microwave material, to thereby facilitate the penetration of heat, which in turn insures the creation of strong bonds throughout the repaired pavement.

[I claim:] [1.]aggregate, comprising gravel, rocks, and the added lossy microwave anthracite material; andasphalt 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. [6.]aggregate, comprising gravel, rocks and added lossy microwave anthracite material; andasphalt cement surrounding the aggregate and forming a resulting coating adopted for distribution on irregular remaining surfaces of failed remaining portions of ways having cracks and potholes in these ways, such as vehicle ways, highways, runways, and walkways, whereby the anthracite, as the added lossy microwave anthracite material in this coating compound, in efficiently intercepting microwave energy to generate heat in this asphaltic concrete coating compound, conducts this generated heat to these irregular remaining surfaces to also insure a good bond to an asphaltic concrete compound filled into these potholes and cracks during repairs of these ways.
