| Summary: | addition, the use of smaller particles of rubber was found to agent (AC-5) showed the least improvement to the addition of apparatus where extreme shear rates and temperatures were are curing time, curing temperature, rubber content (weight asphalt-rubber binder more than the Tire-Gator rubber. The attributed to the devulcanization of the rubber in the mixer carbonyl area. Results confirmed that the addition of rubber curing process was also shown to increase the breakdown of decrease the creep stiffness at low temperatures (< - 152C). Exxon AC-5. With respect to rubber type, the Rouse rubber For example, the Murphy asphalt reblended with Sun recycling guidelines. The purpose of this study is to determine However, it did not increase the viscosity at high increased the viscosity of the asphalt binder at high low temperatures, and improved the overall temperature meeting the criteria of an improved asphaltrubber binder. needed experience, design procedures, and construction of asphalt and the type of rubber play important roles of of the asphalt-rubber binder. The selected variables chosen optimal blend parameters that will enable maximum performance percent), rubber particle size, base asphalt type, and rubber compared with the Fina AC- 10, Exxon AC- 10, and susceptibility. Increasing the rubber content in the asphalt temperatures ( >60QC). It was also determined that the type temperatures, lowered the creep stiffness of the binder at the rubber into the asphalt. This phenomenon can be The use of asphalt-rubber has been mandated without the used. was determined to improve Theological properties of the was shown to further improve pavement performance. In |
