1. A paver for applying polymer concrete to a surface to be paved, said paver comprising:

  • a mobile chassis adapted to move over said surface to be paved, said chassis comprising;

    a rigid, supporting frame having a pair of sides, said frame establishing a plane;

    a plurality of wheels for supporting said frame; and

    ,active suspension means for coupling said wheels to said frame;

    grade control means for sensing changes in grade as the chassis moves over said surface, said grade control means comprising means for extending or contracting said suspension means to orient said plane generally parallel to said surface to be paved;

    a finishing assembly secured to said chassis for distributing and finishing polymer concrete, said finishing assembly comprising;

    distribution means for spreading concrete over said surface; and

    ,a finishing screed disposed adjacent said distribution means for densifying and finishing said concrete;

    means for receiving raw concrete from an external source and conveying it to said finishing assembly;

    steering sensing means for automatically steering said chassis;

    means for referencing an intended resultant plane that is established by the repaired surface; and

    ,logic means responsive to said means for referencing said intended resultant plane for activating said grade control means for extending or contracting said suspension means thereby variably orienting the plane of said frame with said intended resultant plane.
