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.
