A complete rewrite and update of the Basic Asphalt Recycling Manual has been released by the Asphalt Recycling & Reclaiming Association. The first edition of the Basic Asphalt Recycling Manual, pronounced “BARM” as it is better known, was published in 2001 by ARRA. It served the industry well over the last 13 years as the source for information on the asphalt recycling and reclaiming strategies of cold planing/milling/grinding, hot in-place recycling, cold recycling and full-depth reclamation.
The original BARM is recognized around the world as “the book” on in-place recycling, having been translated into Spanish and Chinese. The BARM was the text for the original National Highway Institute course on Asphalt Pavement Recycling Technologies (FHWA-NHI-131050).
Over the last decade there have been numerous improvements and innovations in in-place recycling equipment, materials and methods made by contractors, equipment suppliers and material suppliers, resulting in a need to revise and update the original BARM. As a result of these numerous advances, the new second edition of BARM is more than just minor edits and revisions; it represents a complete rewrite of the original document.
The second edition of the BARM, or BARM II, remained true to the original concept of first edition, serving as a source of general information on the asphalt recycling and reclaiming strategies of cold planing (milling, fine milling and micro milling), hot in-place recycling (surface recycling, remixing and repaving), cold recycling (cold in-place and cold central plant recycling), and full-depth reclamation (pulverization, mechanical, bituminous and chemical stabilization).
