摘要
通过室内车辙试验、小梁弯曲试验、浸水马歇尔和冻融劈裂试验对DOP,SBS,复合改性生物沥青的高低温性能和水稳性能进行评价。试验结果表明,DOP的掺入提升了SBS改性生物沥青混合料的低温抗裂性、高温抗车辙性能和抗水损害性能。
Through indoor rutting test,beam bending test,water immersion Marshall and freeze-thaw splitting test,the high and low temperature performance and water stability of DOP/SBS composite modified bio-asphalt were evaluated.The test results show that the incorporation of DOP improves the low-temperature crack resistance,high-temperature rutting resistance and water damage resistance of the SBS modified bio-asphalt mixture.
