1. Scope
Scope 1.1The use of high viscosity asphalt binders like Asphalt-Rubber is becoming more common in the United States and worldwide. Specifications such as ASTM 6114 note that the field control of the apparent viscosity and require the use of a field production rotational viscotester. The testing of Asphalt-Rubber Binder for use in Asphalt- Rubber Hot Mix and for Asphalt-Rubber Membrane is necessary to ensure consistent mix properties that will ensure good performance of these materials. Logistics of field applications limits use of conventional laboratory controls and testing equipment. 1.2Asphalt-Rubber Binder consists of a blend of paving grade asphalt cement and crumb rubber as described in ASTM 6114. Other high viscosity asphalt binders may consist of asphalts modified with polymer or fiber or both. Testing is performed following the specified reaction time within the production process. Control of the raw materials is separate from the test. 1.3The values stated in SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; each system shall be used independently of the other. Combining values from the two systems may result in non-compliance with the standard.
