【摘要】 针对高比例厂拌RAP热再生沥青混合料开展了应用研究,通过小梁弯曲试验对比评价了RAP比例分别为0%、30%、45%的热再生沥青混合料变形性能,并对RAP比例分别为0%、30%、45%的热再生沥青混合料在广惠高速公路开展了试验段研究,检测评价了试验路的抗车辙、弯沉及回弹模量特点,分析了高比例RAP热再生沥青路面性能特点,总结了高比例RAP厂拌热再生沥青路面试验段应用情况。更多还原

【Abstract】 Study on the application of high percentage RAP in hot recycled asphalt pavement is made.The deformation performance characters of hot recycled asphalt mixture with 0%,30%,45% RAP are compared through beam bending test.Test sections of hot recycled asphalt pavement with 0%,30%,45% RAP are made in Guanghui freeway.The characters of rutting,deflection and resilient modulus of test sections are tested and analyzed.The characters of test section of hot recycled asphalt pavement of high percentage RAP in Guanghui freeway are analyzed.更多还原
