| Description | The objective of this study was to characterize several different types of CRM modified binders and to develop trend information relation their properties. Different concentrations, gradations, and asphalt cement sources were evaluated to determine if any of those factors caused changes in the properties of the modified binders. The asphalt and rubber were reacted at 350 F until the stiffness had reached a maximum level. Tests were performed to evaluate both the reaction properties and the final properties of the binders. The concentration was found to have the largest effect on the final properties of the binders. It was not clear that the asphalt cement had any effect on the way the rubber reacted with the asphalt, although there was some difference found in properties of the mature binders. SHRP binder properties indicated that the asphalt rubber performed better than the base AC-10 used to make the binders, and better that an AC-20 used to compare to the asphalt rubber binders. Conventional asphalt tests were also performed on the mature binders. |
