| Summary: | additional studies. A1l asphalt-rubber binders in this after the second cure. The settling rates and the asphalt by using a high shear rate quickened the asphalt-rubber binder is desirable for alleviating benefited low temperature properties. Low molecular between asphalt and rubber. Increasing the curing time blends. conducted with an expectation of improving high curing step. Finally, the re-settling step was dissolved into asphalt, due to increased reaction dissolved rubber content is expected to have better effect of different curing conditions. The effect of elucidate the effect of curing conditions on the employed to remove a small part of the remaining grade of the binders seemed to be deteriorated by has been investigated to attain an optimal process, in pavement compaction, due to phase separation or more efficiently solubilities the ground tire rubber. nitrogen versus air blowing as variables to study the noticeably increased the size reduction and the performance grades of the blends were determined to performance properties. A variety of curing processes processes. The first curing was used to produce the providing a superior asphalt-rubber blend. This quality of the binders. The high curing temperature research used temperature, time, shear rate, and research were prepared by a two step curing process. resulted in more rubber being disintegrated and rubber content, asphalt type, and air blowing were sedimentation of undissolved rubber. A homogeneous shortening of rubber chains. However, the performance solubility of the rubber particles. Mixing rubber with temperature properties while the added rubber the first and the second curing, and two settling the undissolved rubber for re-curing in the secondary Then, the settling step was followed to concentrate these severe curing conditions. Air blowing was this problem. In addition, a blend with a high This process consists of two curing processes, called Traditional asphalt-rubber binders have faced problems ics. undissolved rubber and to determine the homogeneity weight asphalt or low viscosity asphalt appeared to |
