Research and Development of Stabilized Rubber Modified Asphalt (SRMA) for Stress Absorbing Membrane Interlayer (SAMI) Binder of Asphalt Pavement in the Xinjiang Uygur Autonomous Region
To prevent reflective cracking of asphalt pavement in the Xinjiang Uygur Autonomous Region, stabilized rubber modified asphalt (SRMA) was developed with Karamay No. 90 petroleum asphalt and Kuqa No. 60 petroleum asphalt. Lab test results show better storage stability and workable performance than traditional AR, and similar performance with SBS modified asphalt commonly used in Xinjiang. A sand anti-fracture (SAF) mixture was designed with developed SRMA as a stress-absorbing membrane interlayer (SAMI) of asphalt pavement. Engineering properties - including high-temperature performance, low-temperature performance, moisture stability and fatigue performance, and mechanical properties - were laboratory evaluated and analyzed. Results show good performance of SAF mixture with SRMA as SAMI. SAF mixture with SRMA designed in this paper has been applied as SAMI in expressway construction engineering of Xinjiang in 2013, and the long-term performance is still been under observation.
