1. A method for filling a pot hole comprising:
- placing an ethylene-unsaturated carboxylic acid copolymer wherein the carboxylic acid is selected from the group consisting of acrylic acid, methacrylic acid, ethacrylic acid, crotonic acid, vinyl acetic acid, maleic acid and fumaric acid and wherein the carboxylic acid comprises 12 to 35 weight percent of the copolymer into the pot hole at ambient temperature;
placing aggregate in the pot hole;
heating the mixture of copolymer and aggregate with an infrared heat source until the copolymer is melted; and
removing the heat source.

Abstract
A pot hole filling formulation comprises a polyolefin preferably ethylene acrylic acid in combination with an aggregate preferably gravel particles of one-quarter inch dimension or larger. The polyolefin, preferably in pellet form is mixed with the aggregate and applied to the pot hole. A heat source melts the polyolefin and causes it to flow within the pot hole to fill up the crevices in the pot hole. A second layer of aggregate is applied to the top surface of the fill before the polyolefin hardens to improve the skid resistant qualities of the fill as well as to minimize any deleterious effects of ultraviolet light from the sun.

10. A method for filling a pot hole extending into the base of a roadway comprising the steps of:
-
patching the base by the steps of; placing an ethylene-unsaturated carboxylic copolymer wherein the carboxylic acid is selected from the group consisting of acrylic acid, methacrylic acid, ethacrylic acid, crotonic acid, vinyl acetic acid, maleic acid and fumaric acid and wherein the carboxylic acid comprises 12 to 35 weight percent of the copolymer into the pot hole at ambient temperature; placing aggregate into the pot hole; heating the mixture of copolymer and aggregate, which forms a base layer, with an infrared heat source until the copolymer is melted, the mixture having a top surface approximately even to slightly higher than, the remainder of said base; removing the heat source; and filling the remainder of the pot hole with a top layer by the steps of; placing copolymer into the pot hole at ambient temperature; placing aggregate in the pot hole; heating the mixture of copolymer and aggregate with an infrared heat source until the copolymer is melted; and removing the heat source. - View Dependent Claims (11, 12, 13)
