| Summary: | 10 asphalt. Air blowing also seemed to lead to an addresses the phase separation that is commonly encountered Air-blown asphalt-rubber blends experienced as many as three also improved the low temperature performance grade. Thus, asphalt binder utilized for the blend seemed to have a asphalt binder, which was likely enhanced by the reduction in between production and use. Air blowing, accompanied by high binder. The addition of 10% by weight rubber to the binder chemical tests to elucidate the performance, rubber particle conditions. This investigation revealed that air blowing curing a binder with the addition of air and rubber was found to cause a substantial increase in the performance grade span. In addition, several blends, which were high temperature performance grade increases compared to the high temperature performance grade of the neat, original improved the performance (as determined by the SuperpaveTM improvement in the stability of the rubber particles in the in the construction of flexible pavements. This work many asphalt-rubber blends in an attempt to discover a binder modified binders were subjected to various physical and of time, were found to resist phase separation. The type of particles that occurred. For example, blends with a resin as performance grading procedure) of the asphalt-rubber blends. Recently, crumb rubber modifier or CRM has become prevalent separation) with the rubber modifier than blends with an AC- shear mixing at elevated temperatures, was used to produce significant effect on the extent of settling of the rubber size, and oxidation as a function of curing time and curing subjected to an elevated temperature for a prolonged period the asphalt type exhibited more compatibility (less the rubber particle size due to air blowing. which resists phase separation. These air-blown, rubber- with asphalt-rubber binders subjected to prolonged storage |
