1. An apparatus adapted to determine at least one macroscopic surface characteristic of a roadway surface material, said apparatus comprising:

  • at least one material-interacting device and computer device configured to;

    (a) interact with the roadway surface material in situ for determining at least one surface dimension measurement thereof; and

    (b) manipulate the at least one surface dimension measurement so as to determine at least one of a macro texture characteristic and a micro texture characteristic of the roadway surface material,wherein the at least one material-interacting device is configured to determine the at least one surface dimension measurement of the roadway material using a light for interacting with the roadway surface material and the computer device is configured to be capable of determining a representative surface dimension from a plurality of the at least one surface dimension measurement;

    wherein the roadway surface material is an exposed surface.
