The guide will provide direction for practitioners that test rubber modified asphalt. The guide will detail changes and modifications to existing methods and standards that are necessary to accommodate the presence of recycled tire rubber, or particulates from dissolved tire rubber in order to produce repeatable results.
KeywordsRecycled Tire Rubber, Performance Grade, Rheology, Viscosity, Multiple Stress Creep and Recovery, Dynamic Shear Rheometer, Rubberized Asphalt, Asphalt-Rubber.
The guide is needed to help new practitioners understand the state of the practice for testing rubber modified asphalt. Some modifications are needed in various methods, this guide will share the experiences of skilled practitioners with the use of tire rubber and help ensure that meaningful and reproducible results can be obtained.
