'OPEN' STATES REFINE ASPHALT RECYCLING SPECS. ASPHALT RECYCLING AND RECLAIMING SPECIAL REPORT

The results are tabulated of an exclusiive survey by Roads & Bridges. The survey shows that asphalt recycling specifications have remained largely unchanged in the U.S. since last year, and that some states with 'open' specifications are getting more specific. Oklahoma and South Dakota had major revisions to their specifications. Okalhoma amended its open specifications to permit maximum RAP percentages in batch and drum plants to 40% in base, 40% in binder, and 0% in the surface course, and excludes modifying agents in recycling. In South Dakota specs have been amended to allow 50% RAP in base, binder and surface courses produced from drum plants. Blended stock piles are no longer allowed, and modifying agents are permitted. Comments are made on other state specifications. The survey attempts to provide a point of central reference that summarizes the basic specs for hot recycling.
