DESIGN AND CONSTRUCTION OF ASPHALT PAVING MATERIALS WITH CRUMB RUBBER MODIFIER

摘要: This document is a concise overview of the terminology, processes, products, and applications crumb rubber modifier (CRM) technology. technology includes any use scrap tire in asphalt paving materials. In general, CRM can be divided into two categories, wet process dry process. When incorporated an material, it will modify properties binder (asphalt rubber) act as aggregate (rubber-modified hot-mix asphalt). The crack joint sealant common across country routinely used by many state maintenance crews. A surface treatment using spray application called stress-absorbing membrane (SAM). materials has broad variability potential. Composite designs with are two-layer system three-layer system. growing nationwide interest alternative uses for tires provided technologists catalyst to develop new concepts applying CRM. major been generic mixes continuous blending There principal unresolved issues related On national level, ability recycle containing not demonstrated. At local these modified must field evaluated establish expected levels performance.
