文摘

ECB does not improve rutting performance when directly added to SMA mixture. Rheoflat improves rutting performance when directly added to mixture SMA. Blending Rheofalt with bitumen is more efficient than direct addition to mix. Rheofalt and SBS modified binders have almost the same rutting performance. Rheofalt and SBS have greater rutting performance enhancement than ECB.
