摘要
富油RAP(0 mm~8 mm)中沥青含量高,具有较高的回收利用价值。为探讨提高富油部分RAP的再生利用率,结合襄荆高速公路路面专项养护工程,铺筑了30%富油RAP的AC-13上面层和40%富油RAP的AC-20中面层试验段,并进行了室内留样试验。根据室内留样试验结果和试验段铺筑结果表明富油RAP再生混合料综合路用性能优异,经济效益高,具有良好的推广应用前景。
Oil-rich RAP(0 mm-8 mm)has high asphalt content and high recycling value.In order to improve the recycling rate of oil-rich RAP,a test road of AC-13 top layer with 30%oil-rich RAP and AC-20 middle layer with 40%oil-rich RAP was paved with the Xiangjing Highway pavement special maintenance project,and the indoor sample tests were conducted.According to the indoor sample test results and the paving results of the test section,the oil rich RAP recycled mixture has excellent comprehensive road performance,high economic benefits,and has a good application prospect.
