Study on Storage Stability of SBS Modified Asphalt

The evaluation for the storage stability of SBS modified asphalt was made by adding selected inorganic stabilizers, which was reported in China and overseas. The experimental results showed that stabilizer A can improve the compatibility between base asphalt and SBS, the difference between bottom softening point and up softening point in the Isolate Test was about 0.2, which was much less than that of JTJ036-98 standard. So, the modification effect of stabilizer A on storage stability of SBS modified asphalt was the best. That is, in the period of storage and transportation, SBS and base asphalt did not isolate. Some defects were overcome during construction of an asphalt road surface. The adding stabilizer not only reduced the cost of production but also simply the procedure.
