1. A method of milling to form a finished depression into a surface of a road at a select positional placement location using a sequential cooperation between respective milling actions of at least two cutting tools, the method of milling comprising the steps of:

  • a) providing a depression installation machine comprising;

    1) a first cutting tool to provide for a first milling action to mill the surface of the road to remove a first amount of a road material at the select positional placement location;

    2) at least one additional cutting tool, each additional cutting tool to provide for a subsequent milling action to mill the road to remove a subsequent amount of the road material at the select positional placement location;

    b) providing cutting tool elevational height adjustment means to provide for an altering of an elevational height of each respective cutting tool relative to the surface of the road, the respective cutting tools being the first cutting tool and any additional cutting tools, the altering of the elevational height providing for a respective milling action of the respective cutting tools;

    c) providing positional control means to provide for a sequential positioning of the respective cutting tools where the respective milling actions occur at the select positional placement location to provide for the sequential cooperation to form the finished depression at the select positional placement location;

    whereby the depression milling machine forms the finished depression at the select positional placement location utilizing the sequential cooperation between the respective milling actions of the respective cutting tools.
