N.J. Stat. § 27:2-5: Specifications to make fair competition

In selecting alternate pavements for competition with each other the public body in charge of the work shall require the specifications to be so drawn that the competition is in every way fair and reasonable, and, so far as the engineering conditions will permit, the base to be used under the various types of pavement shall be of the same general character, and, so far as the engineering conditions will permit, of the same thickness and width, irrespective of the thickness of the surface pavement. In this particular the judgment of the public body shall be final.
