N.J. Stat. Ann. § 27:1B-25.3

2. Counties and municipalities receiving State funds for transportation projects shall permit for public highways under their jurisdiction the use of reclaimed asphalt pavement that constitutes from 25 to 50% by weight of the total pavement mixture for base and intermediate pavement courses, after an evaluation of the material properties of the reclaimed asphalt pavement, in a "closed system" project. A "closed system" project is defined as a project on which the asphalt millings from the project are recycled back into the hot mix asphalt on that same project.
