ABSTRACT:
A paving mixture containing black asphalt which is changed to a color other than black by the addition of a limited amount of a coloring agent to the mixture, such as ferric oxide, to impart a permanent, distinctive color to the pavement without sacrificing any of the wearing qualities thereof. At the same time, the cost of the pavement is maintained within practical economic limits so that it may be used in the production of paved areas of limited extent, such as tennis courts, playgrounds, running tracks, parking lots, airport runways, etc. When the mixture is laid down in depths of one-fourth inch to twelve inches, the increased cost of the pavement is made up in a reasonably short period of time by the elimination of the need for painting the conventional black surface repeatedly, especially when the latter is subjected to extensive use and wear.
