## Abstract

A fluid pavement sealer composition includes a liquid phase having a sealant component and a fluid component, and at least about 25% by volume of finely divided metal particles suspended within the liquid phase. An electrically heated element contacts a pavement surface, with the solidified pavement sealer layer covering a selected area of the pavement surface including the electrically heated element. The solidified pavement sealant layer includes at least about 25% by volume of finely divided metal particles. The electrically heated element transfers heat to the pavement sealant layer and metal particles therein to maintain the selected area of pavement surface free of ice and snow.

## Claims

### Claim 1

A heated pavement sealant system comprising:
an electrically heated element positioned upon and contacting a pavement surface;
a pavement sealant layer covering a selected area of the pavement surface including the electrically heated element;
the pavement sealant layer including at least about 25% by volume of finely divided metal particles;
whereby the electrically heated element transfers heat to the pavement sealant layer and metal particles therein to maintain the selected area of pavement surface free of ice and snow.

### Claim 2 (depends on 1)

The fluid pavement sealer composition of claim 1, wherein the fluid component is water.

### Claim 3 (depends on 1)

The fluid pavement sealer composition of claim 1, wherein the fluid component is an organic liquid.

### Claim 4 (depends on 3)

The fluid pavement sealer composition of claim 3, wherein the organic liquid comprises a heavy oil selected from the group consisting of alkyd resin oil, linseed oil, soy bean oil, rape seed oil and mixtures thereof.

### Claim 5 (depends on 1)

The heated pavement sealant system of claim 1, wherein the finely divided metal particles have a size no larger than about 20 standard mesh (0.033 inch diameter).

### Claim 6 (depends on 1)

The heated pavement sealant system of claim 1, wherein the finely divided metal particles are selected from the group consisting of aluminum, iron, steel alloy and mixtures thereof.

### Claim 7 (depends on 1)

The heated pavement sealant system of claim 1, wherein the finely divided metal particles have a size no larger than about 20 standard mesh (0.033 inch diameter).

### Claim 8

A heated pavement sealant system comprising:
an electrically heated element positioned upon and contacting a pavement surface;
a pavement sealant layer covering a selected area of the pavement surface including the electrically heated element;
the pavement sealant layer including at least about 25% by volume of finely divided metal particles, the particles selected from the group consisting of aluminum, iron, steel alloy and mixtures thereof;
whereby the electrically heated element transfers heat to the pavement sealant layer and metal particles therein to maintain the selected area of pavement surface free, of ice and snow.

### Claim 9 (depends on 8)

The fluid pavement sealer composition of claim 8, wherein the fluid component is water.

### Claim 10 (depends on 8)

The fluid pavement sealer composition of claim 8, wherein the fluid component is an organic liquid.
