Performance Study of High-Modulus Resin-Modified Asphalt Mixture
High modulus resin was added to the asphalt mixture to prepare high modulus resin modified asphalt.Through the study of rutting test,small beam bending test,freeze-thaw cracking test,water immersion Marshall and fatigue test on the specimens,the effect of two different doses of high modulus resin on the performance of asphalt mixture was discussed.The test results showed that with the increase of high modulus agent dose,when the dose of high modulus agent was 0.6%,the rutting performance and water damage resistance of the asphalt mixture showed a superior effect.This was because the addition of high modulus resin made the overall structure of asphalt mixture more compact,and the cementation between mineral powder,aggregate and asphalt was tighter,which enhanced the elastic modulus and shear resistance of the pavement and prevented the pavement from cracking,peeling and other damages caused by water erosion.This enhanced the water resistance and rutting resistance of the pavement.
