1. An apparatus for determining a condition of a road traversed by at least one load hauling machine having a plurality of tires in contact with said road, comprising:
- at least one parameter sensor connected to said load hauling machine, said at least one parameter sensor being adapted to sense a parameter of said load hauling machine and responsively deliver a parameter signal; and
a control system connected to said load hauling machine, said control system being adapted to monitor a condition of said tires and responsively generate a calibration signal, and to receive said parameter signal and determine a condition of said road in response to said parameter signal and said calibration signal.

20. A method for determining a condition of a road traversed by at least one load hauling machine having a plurality of tires in contact with said road, including the steps of:
-
traversing a reference section of said road, said reference section being in a known and controlled condition; sensing at least one parameter of said load hauling machine and responsively delivering a parameter signal;
determining a load on said tires;determining a machine motion resistance relative to the load in response to said parameter signal; comparing said machine motion resistance relative to said load to a reference machine motion resistance; and generating a calibration signal in response to a difference between said machine motion resistance relative to said load and said reference machine motion resistance; and
determining a condition of said road in response to said calibration signal.

21. An apparatus for determining a condition of a road traversed by at least one load hauling machine having a plurality of tires in contact with said road, comprising:
-
a slope sensor adapted to sense a slope of the grade of said road and deliver a responsive slope signal; a power sensor adapted to sense a power delivered by said load hauling machine and deliver a responsive power signal; an acceleration sensor adapted to sense an acceleration of said load hauling machine and deliver a responsive acceleration signal; a position sensor adapted to sense a position of said load hauling machine and deliver a responsive position signal; and a control system connected to said load hauling machine, said control system being adapted to monitor a condition of said tires and responsively generate a calibration signal, and to receive said slope signal, said power signal, said acceleration signal, and said position signal and determine a condition of said road in response to said slope signal, said power signal, said acceleration signal, said position signal, and said calibration signal.
